32 SOFTLIMIT Sets the use of the softlimiter in the audio circuit.
35 COUNTRY
36 BER
37 OMC
38 ADC
39 DAC
40 INPORT
12
Controls the handsfree attenuation level for RX and TX audio
M+0
selects RX handsfree audio gain settings
and echoes initial gain settings
M+1 selects TX handsfree audio gain settings
and echoes initial gain settings
0-7 sets the gain for the selected path:
0=0dB, 1=-7dB, 2= -14dB, ... 7=-49dB
Changes made are temporary and will not update the EEPROM.
Factory and level 5 repair only

Displays the different hex values from the ADC
M+1 RSSI
M+2 battery voltage
M+3 unused
M+4 temperature sense
M+5
bandgap reference
M+6 current sense
M+7 handsfree level
Changes temporarily the output voltage from the DAC.
M+1
normally controlled by AFC
M+2 normally trimmed using 'MENU 18'
M+3 power level
xxx M+# decimal value followed by 'MENU + #' sent directly
to the active DAC (valid values: 000 - 255)
# / * increases/decreases value by 1; new value is echoed
Shows the status of the different inports (updated every second)
M+1
external audio connection detected
0 = input high
1 = input low
M+2 state of CPU port 2
M+3 flip status
0 = flip closed
1 = flip open
M+4
transmitter status
0 = transmitter off
1 = transmitter on
M+6 external handsfree detected
0 = input low
1 = input high
M+7 receiver carrier detect
0 = RSSI < sensitivity limit
1 = RSSI > sensitivity limit
# immediately reads the selected port
