Test
Description
Audio loopback 
test
Routes audio from the microphone to the radio’s 
internal and external speakers.
Before running this test, turn the volume down to 
limit interference and reduce the impact of audio 
artefacts.
Display freq
Displays the transmit and receive frequencies of the 
current channel. If the radio is scanning this 
information may not be available.
GPS NMEA 
data
Displays the last raw data received from a GPS 
antenna/receiver connected to the radio. The radio 
will display all supported sentence formats received 
(for example $GPRMC and $GPGGA sentences). 
Note that the display will not automatically refresh 
when new data is received.
Keypad test

released on the radio. The radio also displays the 
key name along with “pressed” or “released”.

(received signal strength (RSSI) with an indication of 
digital voice quality).

Displays the received signal strength (RSSI) of the 
current channel.
Rx 1011 or

the received signal strength (RSSI) and the bit error 
rate (BER) of the received signal.
