The dual band DMR and analog handheld with 4000 channels, a recorder and built in APRS. Keys, the whole programmable key list, both settings menus in full, and the settings that decide whether it works on a hotspot. Condensed from the operating manual.
Before anything else, two things
The keypad ships locked. AnyTone lock it at the factory to satisfy FCC rules. Press the Menu key and then the star key to unlock it the first time you use the radio. A radio that appears dead to every keypress is almost always this and nothing else.
Read the radio before you write to it. Connect the programming cable, READ the radio with the CPS, and save that file. It is the factory codeplug and it is your only way back. Edit that saved file and send it back; starting from a blank one causes errors.
A dual band DMR and analog handheld, 4000 channels across 250 zones, doing digital and analog on either band with a sub band running alongside the main one. On top of the DMR basics it carries text messaging, a 14 hour voice recorder, digital encryption, emergency and man down alarms, work alone, GPS with APRS position reporting, roaming, vibration, and the analog signaling set of DTMF, 2TONE, 5TONE and CTCSS or DCS.
Almost everything of consequence is set in the CPS programming software rather than on the radio. The radio menu can change most of it after the fact, but scan lists, zones, contacts, hot keys, roaming lists and the APRS setup all have to be built on a computer first.
The EU declaration on this manual covers the AT-D890UV, AT-D890UVII, AT-D890UV PLUS and AT-D890UV PRO, so the family shares this documentation.

On a digital channel the radio answers anything on the same frequency, color code and slot. If the caller's DMR ID is in your contact list the radio rings or vibrates, the LED lights, and the screen shows the ID, name, city, state, country and call type. When it ends the screen says "Call end" and PTT replies to it.
Hold the radio upright, 2.5 to 5 cm from your mouth.
Set per channel in the CPS, and this is what stops PTT working when you think it should.

The cross band repeater has conditions
It has to be UHF to VHF or VHF to UHF. That holds for DMR to DMR, analog to DMR, DMR to analog and analog to analog. Same band will not work.
Turn digital monitor off before using it, and have both the main and the sub channel on. While the radio is acting as a repeater it is locked, and you have to wait for a call to finish before you can switch it off or stop repeater mode.
| Item | Options |
|---|---|
| Repeater | Turns the cross band repeater on. |
| Rep CC Limit | Off passes everything. Otherwise only calls matching channel A's or channel B's color code get repeated. |
| Rep Slot Path A | Off means a call received in one slot goes out in the other. Fixing channel A to slot 1 sends out on channel B slot 2, and the reverse. |
| Rep Slot Path B | The same for channel B. Setting either path makes the DMR mode setting on both channels inactive. |
| SMS Format | M-SMS is Motorola, H-SMS is Hytera, or the ETSI DMR standard. |
| TX Preamble | How long a preamble goes out ahead of data, SMS or a private call, to wake a receiver from power save or pull it out of a scan. |
| Voice Hdr Rpt | How many times the voice header repeats before the audio. More repeats improve the odds the far end syncs up. |
| Item | Options |
|---|---|
| Auto Power Off | Off, or after 10 minutes, 30 minutes, 1 hour or 2 hours idle. |
| TX Timer | Off, or 30 to 240 seconds before transmit cuts. |
| TOT Predict | Beeps five seconds before the timeout timer expires. |
| TXPow ALC | Drops transmit power in proportion to the strength of the received signal. |
| Freq Step | 2.5, 5, 6.25, 10, 12.5, 20, 25, 30, 50 kHz. |
| Ana SQ Level | Five squelch levels. Analog only. |
| Power Save | Save 1 works 30 ms and sleeps 30 ms. Save 2 works 60 ms and sleeps 30 ms. Either can miss the start of a message. |
| TBST Sel | 1000, 1450, 1750 or 2100 Hz. Send it with PTT and PF1 together. |
| VOX | Three levels. |
| VOX Delay | 0.5 to 3 seconds. |
| Scan Mod | SCM TO, SCM CO or SCM SE. See the scan section. |
| DTMF Speed | 50 to 500 ms. |
| AM Air/FM | Off, FM radio, AM air on band A, or AM air on band B. |
| FM Radio Moni | On lets you still work the channel while the FM radio plays. Off blocks transmit and receive. |
| AM Offset | Offset for the AM air channel. |
| AM Sq Level | Squelch for the AM air channel. |
| Man Down Alarm | Alarms if the radio falls. Lifting it stops the alarm. With GPS fixed it sends the position automatically. |
| Start Up Pwd | Password at power on, set in the CPS under Optional Setting, Power on. |
| AuRepeater A and B | Off, Positive or Negative. Applies the CPS offset to the VFO transmit frequency. |
| VFO SC-MinU / MaxU / MinV / MaxV | Start and end frequencies for the UHF and VHF VFO scans. |
| CTC STE | Blanks the noise burst at the end of a CTCSS transmission. |
| DCS STE | The same for DCS. Simplex radio to radio only. |
| No-Signal Ste | Squelch tail eliminate with no signaling at all. |
| Time Zone | Your zone. Set it, or the date and time will be wrong. |
| Time Display | Shows or hides the date and time. |
| Date Time | Set by hand, or GPS Check corrects it from the satellites. |
At Menu → Settings → Chan Set. The menu changes with the channel type, hiding the analog items on a digital channel and the reverse.
| Item | What it sets |
|---|---|
| New Chan | Creates a channel from the current settings. Asks for a number, a name and a zone. |
| Delete Chan | Deletes the current channel and moves to the next. |
| Channel Type | A-Analog, D-Digital, A+D TX A (receives both, transmits analog), D+A TX D (receives both, transmits digital). |
| TX Power | Power for this channel. |
| Offset | Offset frequency. The manual notes this is primarily for use with a hotspot. |
| Band Width | 12.5 kHz narrow only, on digital. |
| RX Freq / TX Freq | Typed on the keypad, Menu saves, P2 goes back. |
| Talk Around | Both ends set this to work direct without the repeater, using the receive frequency for both. |
| Name | Channel name. Channel mode only. |
| TX Allow | Always, Channel Free, Different Color Code, Same Color Code. Normally Channel Free. |
| TX Prohibit | Blocks transmit on this channel entirely. |
| Radio ID | Which of your DMR IDs this channel uses. One per channel, from the CPS DMR ID list. |
| Time Slot | Slot 1 or slot 2. |
| RX CC / TX CC / R&T CC | Color codes. Setting R&T CC overwrites the separate ones. |
| Digi Encrypt | 32 groups available, set in the CPS or on the radio. |
| Encrypt Type | Normal or enhanced. |
| RX Group List | Select, add a talk group, or remove one. |
| Work Alone | Times you and alarms if you do not confirm. Response and warning times come from the CPS. |
| CH Ranging | Automatic ranging on any channel whose contact is a private call. |
| APRS Receive | Shows the other radio's distance and position when receiving, if both have GPS. |
| SMS Forbid | Refuses incoming messages. |
| DataAck Forbid | Ignores repeater data service requests such as call and SMS confirmations. |
| TX interrupt | Lets a supervisor talk over an ongoing transmission. |
| Digi TX Idle | Moves to the other slot when one is busy. Both ends need it on. |
| Slot Suit | Ignores the slot setting when frequency and color code match. |
| CRC Ignore | Lets the vocoder ignore the CRC on the voice header, so the radio hears more signals. |
DMR Mode, the setting that decides whether a hotspot works
The manual recommends Repeater for normal use, and that is the one a hotspot needs.
Repeater: through a repeater or hotspot, same slot for transmit and receive.
DMO / Simplex: radio to radio only, no repeater or hotspot. Transmit and receive frequencies may differ as long as the other radio mirrors them.
DCDM / Double Slot: radio to radio only, same frequency both ways, with the slot used to separate two channels.
DCDM / TS split: through a repeater or hotspot with different slots each way. The slot chosen in the channel is the receive slot, and transmit takes the other one automatically.
Everything not listed here works as it does on a digital channel.
| Item | What it sets |
|---|---|
| TCDT / RCDT / RTCDT | CTCSS or DCS for transmit, receive, or both. 51 CTCSS tones from 62.5 to 254.1 Hz, and 1024 DCS codes from 000N to 7771. |
| Optional Signal | DTMF, 5TONE or 2TONE encode and decode. |
| Squelch mode | SQ opens on carrier. CDT needs matching CTCSS or DCS. TONE needs matching signaling. C&T needs both. C|T accepts either. |
| Band Width | Wide or narrow. |
| Reverse | Swaps the frequencies and the CTCSS or DCS encode and decode. |
| Compander | Cuts background noise and sharpens audio, mostly on long paths. |
| Scrambler | Other radios on the frequency hear only noise. |
| Busy Lock | Always transmits, RL blocks on a matched carrier with unmatched tone, BU blocks on any matched carrier. |
| OWN ID | Shows the 5TONE or DTMF self ID set in the CPS. |
| DTMF Enc | Default DTMF ID sent on PTT. |
| 2Tone Enc / 5Tone Enc | Default 2TONE or 5TONE caller ID sent on PTT. Both must be written in the CPS first. |
| 5Tone BOT / EOT | Sends the 5TONE ID when PTT is pressed, released, or both. |
| QDC Enc | A predefined QDC1200 ID, when the optional signal is QDC1200. |
| PTT ID | Off, Start, End, or Start and End. Needs the optional signal set to DTMF or 5TONE with the BOT and EOT configured. |
| APRS Receive | Receives analog APRS on this channel. Frequency and tone have to match the sending station. |
Each call is saved separately with its DMR ID and time. The radio holds about 14 hours in digital or analog, and the files come off in the CPS under Tool, Radio Recording.
The promiscuous mode. Four settings decide how wide it listens.
| Setting | Options |
|---|---|
| DigiMoni Switch | Off, Single Slot (the current one), or Double Slot (both). |
| DigiMoni Cc | Any color code, or only the matching one. |
| DigiMoni Id | Any talk group, or only the matching one. |
| Slot Hold | Recommended on when monitoring both slots. When the signal drops in one slot the radio waits a few seconds rather than jumping straight to the other. |
While a call with an unmatched ID is coming in, one key sets up a response so PTT answers it, and another offers to save it as a new channel in a zone you pick.
If you are hearing traffic you did not ask for
The manual's own troubleshooting answer: turn digital monitor off, both single and double slot, and the radio goes back to hearing only the programmed talk group or the station in a private call. Digital monitor is also the thing that has to be off before the cross band repeater will work.
Upload Type picks none, analog APRS or DMR APRS.
Intervals Set gives automatic transmission on a timer. Upload Beacon chooses the GPS beacon, which needs GPS on and locked, or a fixed beacon whose position is set in the CPS and which works with GPS off.
Most of the APRS setup is CPS only, and the APRS menu does not even appear in the software until you tick the APRS box under Tools, Options, APRS.
The weather channel always runs on the sub band. With WX alarm on, the speaker stays muted until a 1750 Hz tone arrives, then opens and alarms for three minutes before muting again. WX monitor leaves the speaker open so the broadcast plays continuously.
| Channel | Frequency | Channel | Frequency |
|---|---|---|---|
| WX1 | 162.550 MHz | WX6 | 162.500 MHz |
| WX2 | 162.400 MHz | WX7 | 162.525 MHz |
| WX3 | 162.475 MHz | WX8 | 161.650 MHz |
| WX4 | 162.425 MHz | WX9 | 161.775 MHz |
| WX5 | 162.450 MHz | WX10 | 163.275 MHz |
A reset takes your codeplug with it
Save the codeplug to the computer before any firmware update or reset, because it has to be written back afterwards. Set the time zone during the restart or the date and time will be wrong from then on.
| Symptom | The manual's answer |
|---|---|
| Will not switch on, or no display | Reseat the battery, then charge or replace it. |
| Battery does not last | The pack is worn out. Replace it. |
| Cannot hear or reach your group | Check the frequency and CTCSS match, check you are in range, check the digital mode and frequency are right, and in digital check the color code, encryption group, receive contact and receive group. |
| Hearing people who are not in your group | Analog: change the CTCSS or DCS on every radio in the group. Digital: turn digital monitor off, both single and double slot. |

The radio holds more than one DMR ID, so a single radio can carry a commercial ID and an amateur callsign ID at once. They live in the CPS under Digital, Radio ID List, and each channel picks one.
It also keeps a separate database for the worldwide contact list, imported as comma separated values, which is what puts a callsign, name and location on screen when someone you have never worked calls in.
