▲▲▲▲▲▲Important Notes:

After this update, you must use the new CPS to re-edit the frequency points and write them to the walkie-talkie. Previous archive files cannot be used.

1. Unicode Download

After the firmware update, this tool is required to load Unicode encoding; otherwise, SMS text may be garbled.

2. DMR Upgrade V1.2.0.32 260130

1. Modified the order of setting default channel parameters in commands 82/83.

2. Fixed the error of falsely reporting sleep-on messages under relay channels.

3. Modified the tail tone transmission duration and addressed the issue of incorrect CT tail tone detection.

3. Walkie-talkie Firmware

V3.18 251111

1. Added automatic recovery of abnormal data and adjusted some data storage locations to avoid data loss due to frequent data changes.

2. Expanded the basic contacts to 10,000.

3. Changed the receiving group list to 250 groups, with a maximum of 32 group call contacts per group. 4. The area list has been changed to 250 areas, each with 250 channels. The current channel for channels A and B in different areas can be set individually.

5. The SMS draft box, inbox, and outbox are all locked to 128 SMS messages.

6. The radio now has 80 independent radio channels, no longer divided into areas. The * key can be used to switch radio input items. When the channel name is selected, pressing the Menu key will enter the name editing mode.

7. The spectrum function has been changed. The spectrum step input range is now 0-9.99999MHz, and the number of spectrum scan points has been increased from 81 to 105. The three indicators on the left, from top to bottom, are RSSI, Noise, and Glitch.

8. The APO, FM Stanby, and other menus have been moved to the Basic Set menu. The FM Radio and Time Manage menus have been removed.

9. The DMR Version, Flash IC, and battery voltage display menus have all been moved to the Version menu. Users can use the up and down keys to navigate through the corresponding items in this menu.

10. The step frequency settings have been refined (8.33kHz is now selectable). 11. Adjusted contrast settings to avoid issues with the display being unclear due to excessively high or low contrast.

12. Adjusted dual-frequency standby processing. In dual-frequency standby mode, if a signal is received on the digital channel, the system will wait for 2 seconds on that channel after the signal ends before resuming dual-frequency standby.

13. Reduced scan speed back to an earlier version (excessively fast scan speeds may prevent some users from scanning valid signals). Waiting time after carrier loss (Scan Interval menu) in CO mode adjustment:

14. Optimized communication between DMR baseband and MCU, optimized some communication commands.

15. Removed color code scanning function.

16. Digital and analog channel settings are no longer separate; digital or analog channel parameters can be set under the Channel Set menu, and digital or analog operating modes can be switched.

17. Offset Freq and Offset Dir menus are merged into the Offset Freq menu. The + or - key can be used to switch between them. This menu is linked to the TX Freq menu; changing one will change the other. Only one needs to be used.

18. Added a timer for Single Tone transmission; transmission will stop when the timer expires.

19. Fixed the issue of transmission freezing during reception.

20. Fixed the issue of potential reception failure after prolonged dual-mode (digital and analog) monitoring.

V3.19 251113

1. Fixed the issue of the Receiver Group List (TG List) not working. 2. Fixed the issue where backup debugging was not invoked when debugging data was incorrect.

V3.20 251119

1. Fixed the issue where initialization data failed to be invoked when debugging data was abnormal.

2. Fixed the issue of incorrect draft saving.

3. When the call contact is a group call contact, group call calls from that group can be received by default.

4. Fixed the issue where color codes were not detected in promiscuous mode.

5. Fixed the issue of abnormal initialization of button definitions during initialization.

6. Fixed the issue where analog voice control was not restricted when channel transmission was limited.

7. Removed the operation of turning off audio during 4819 initialization to avoid signal transmission during 4819 initialization.

8. Fixed the CTC/DCS setting issue.

9. Fixed the issue of not being able to change CTC/DCS when using digital channels.

V3.21 251209

1. Fixed the issue where DMR could not be debugged during production debugging.

2. Fixed the issue where frequency measurement decoding could not save non-standard sub-audio.

V3.22 251215

1. Fixed the issue where current area information data was abnormally cleared. 2. Fixed the issue where the small text at the bottom did not change with the call channel when entering the receiving call interface on a digital channel.

3. Fixed the issue where, in area mode, exiting a scan did not return to the initial channel when the initial channel was set after scanning.

4. Fixed the issue where manual channel switching failed in area mode.

5. Fixed the issue where frequency measurement decoding and remote sub-tone decoding functions could not lock sub-tone frequencies.

6. Removed the frequency input restriction for digital channels.

V3.23 260121

Testing the new DMR firmware

V3.24 260203

1. Fixed the issue of invalid scan interval time in digital channels.

2. Disabled the digital call AGC function.

3. Fixed the occasional popping sound from key presses.

4. Addressed the issue of the carrier indicator light not turning off.

5. SMS notification tones are no longer controlled by voice broadcast.

6. Increased call hold time (including individual and group calls) to a maximum of 60,000ms.

7. Fixed the issue of digital channel polite access settings not taking effect.

8. Added a "Jump to Contact" option to key definitions. 9. Added a "Jump to DTMF Code Selection" option to the button definitions.

10. Under the "DTMF Code Selection" menu, pressing the dial key (green key) will transmit the DTMF code currently specified by the cursor once.

V3.25 260205

1. Fixed the issue of no power-on prompt tone in version 3.24.

4. CPS

V2.01 251111 (Incompatible with all previous versions; please re-edit the frequency point for programming)

1. Read/write frequency rate can be selected as 115200 (default) or 256000. If using 256000, the walkie-talkie needs to be powered on by pressing and holding the # key (some customers' programming cables do not support 256000; please downgrade to 115200).

2. Interface layout adjustments.

3. VFO channels moved to the front; digital and analog channels are now processed together. In channel mode, a right-click menu (Copy/Cut/Paste/Insert/Delete) has been added. Channels can now be searched by frequency or name, and channels can be sorted by frequency/mode/name.

4. Working areas have been increased to 250 zones, each with 250 channels. Channels can now be moved up and down and sorted by channel number/name. Each zone now has two current channels, corresponding to the current channels of channel A and channel B respectively.

5. The number of contacts has been increased to 10,000. Sort options by type/ID/name have been added.

7. The receiver group list has been changed to 250 lists, each with 32 group call contacts.

8. The radio is now a separate list with 80 channels, no longer divided into zones.

V2.02 251113

1. Fixed the issue where the ID in the receiver group list (TG List) did not update when the contact ID changed.

V2.03-V2.04 251119

1. Added buttons for searching by name, searching by ID, and appending a CSV file to the contact list.

2. Added a pop-up window asking whether to save data when exiting the window.

3. Fixed the issue of preset SMS writing not working.

V2.05 251215

1. Added a button to the channel list to import channel CSV files from older versions. Channel CSV files from CPS versions prior to V2.01 can be directly imported into the new CPS without needing to be re-edited.

V2.06 260204

1. Added two options to the key definition: jump to call contact and jump to DTMF code selection.

2. Automatically corrected the error of Channel ID being 0 in the CSV file when importing files.
