Menu operation

The menu can be accessed with the M button (short press).

Once in the main menu, the menu items will be displayed on the left-hand side of the screen. The currently selected menu item will be highlighted and current value for that menu item will be shown on the right. Also, at the bottom left side a number of the menu item will be shown, ranging from 01 to the highest number.

To find the menu item to access, the UP/DOWN arrow keys may be used, or the menu item number (see lists below) may be entered on the numeric keypad. For instance, to access the VOX settings a number 48 can be entered on the keypad.

Once the desired menu item is highlighted, pressing the Menu key will enter into that menu item.

Once the menu item is selected, pressing the up and down arrow keys will adjust the setting for that menu item. To confirm the selection, press the Menu key. To cancel the selection, press the EXIT key.

Main menu

The number in front of the menu-item-description is an menu item number that can be used for quick selection.

  1. Step - step of the frequency (in kHz), up/down buttons change frequency by this value, also you can only set a frequency that is multiple of this value. 2.50/5/6.25/10.00/12.50/25.00/8.33 are the steps that can be set by programming software, all other steps are extension from standard software, and can only be selected from this menu entry.
  2. TxPwr - radio output power (LOW/MID/HIGH)
  3. RxDCS - receiver Digital-Coded Squelch, if you enable this, squelch will only unlock if this code is being received. You can start a DCS/CTCSS scan while you are in this menu option by pressing * SCAN button
  4. RxCTCS - receiver Continuous Tone-Coded Squelch System, squelch will only unlock if this code is being received. You can start a DCS/CTCSS scan while you are in this menu option by pressing * SCAN button
  5. TxDCS - transmitter Digital-Coded Squelch, radio will send given code while transmitting
  6. TxCTCS - transmitter Continuous Tone-Coded Squelch System, radio will send given code while transmitting
  7. TxODir - transmitter frequency offset direction
  8. TxOffs - transmitter frequency offset value
  9. RxOffs - offsets the receive frequency by any specified amount for use with upconverters, allows to fine tune the frequency (1kHz resolution) as opposed to other implementations that use hardcoded offsets, this once set will also allow to tune below 18Mhz limit
  10. W/N - bandwidth used by transceiver
    • WIDE - 25kHz
    • NARROW - 12.5kHz
  11. Scramb - scrambler, distorts the audio so it would be harder to understand for other listeners, if two radios use the same setting they can communicate
  12. BusyCL - busy channel lockout, blocks radio from transmitting because signal is being received (with BUSY on screen while PTT is pressed)
  13. Compnd - compander (compressor/expander), allows signals with a large dynamic range to be transmitted over facilities that have a smaller dynamic range capability, improves audio quality, both radios should use this option
  14. Demodu - demodulator mode, default is FM, AM/USB can be used for listening only
  15. ScAdd1 - add channel to scan list 1
  16. ScAdd2 - add channel to scan list 2
  17. ChSave - save current setting to a memory channel
  18. ChDele - delete memory channel
  19. ChName - modify memory channel name
  20. SList - selects which channel is used by memory channel scanner
  21. SList1 - channels assigned to scan list 1
  22. SList2 - channels assigned to scan list 2
  23. ScnRev - scan resume mode
    • CARRIER - resume scan after signal disappears
    • TIMEOUT - resume scan after 5 seconds pause
    • STOP - after receiving a signal, stop the scan
  24. F1Shrt - side button 1 short press function
  25. F1Long - side button 1 long press function
  26. F2Shrt - side button 2 short press function
  27. F2Long - side button 2 long press function
  28. M Long - menu button long press function
  29. KeyLck - auto keypad lock option
  30. TxTOut - max transmission time limit
  31. BatSav - battery save option, the rate between active time and sleep time (OFF/1:1/1:2/1:3/1:4)
  32. Mic - microphone sensitivity (+1.1dB .. +15.1dB)
  33. MicBar - microphone bar that appears while transmitting
  34. ChDisp - channel display style (Name + Freq or Number)
  35. POnMsg - power on message
  36. BatTxt - additional battery value on the status bar in % or V(oltage)
  37. BackLt - backlight duration (OFF/ON/configured Time)
  38. BLMin - minimal backlight brightness, when the screen backlight turns OFF it will go dim to this value
  39. BLMax - maximal backlight brightness, when the screen backlight turns ON it will turn bright to this value
  40. BltTRX - backlight activation on TX or RX
  41. Beep - keypad press beep sound
  42. Roger - roger beep at the end of transmission (OFF/ROGER/MDC1200)
  43. STE - squelch tail eliminator, eliminates noise at the end of a transmission
  44. RP STE - repeater squelch tail eliminator
  45. 1 Call - one key call channel, lets you quickly switch to the channel with 9 Call button
  46. D Live - displays DTMF codes received by radio in the middle of the screen
  47. AM Fix - activates autogain AM fix function
  48. VOXSen - VOX sensitivity - voice TX-activation sensitivity level VOX Setting (OFF/1 .. 10, 1-min sensitivity, 10-max sensitivity)
  49. VOXDel - VOX delay. Use 0 for For Packet Radio, APRS, etc. (range of 0-10, increment of 128ms (4 = default)) ???
  50. BatVol - battery voltage and percentage
  51. RxMode - sets how how the upper and lower frequency is used
    • MAIN ONLY - always transmits and listens on the main frequency (NO extra characters on screen)
    • DUAL RX RESPOND - listens to both frequencies, if signal is received on the secondary frequency it locks to it for a couple of seconds so you can respond to the call (DWR on screen)
    • CROSS BAND - always transmits on the MAIN/primary and listens on the secondary frequency (XB on screen)
    • MAIN TX DUAL RX - always transmits on the primary, listens to both (DW on screen)

Explanation of how these modes function

  • The main channel is marked ► and with PTT active ►TX
  • A receiving channel is marked RX as soon as a signal is received. Other VFO/channel is blocked from RX.
  • With DUAL RX RESPOND, the secondary VFO/channel is marked > as temporarily the main channel when something is received there.
  • If nothing is received after a timer of 4 seconds (>< on screen), that status will expire.
  1. Sql - squelch sensitivity level (0=OFF/1 .. 9)
