Test Description
Audio loopback
test
Routes audio from an external accessory
microphone to the radio's internal speaker.
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. Also displays the channel status
(CNV, TCH, CCH
1
) and the mode (ANA, PH1 or
PH2
2
). If the radio is scanning this information may
not be available.
GPS NMEA
data
Displays the last raw data received from the radio’s
internal GPS. 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 Sounds an audible tone when a key is pressed or
released on the radio, or the 16-way and 3-way
selectors are moved. The radio also displays the
key or selector name along with “pressed” or
“released” or the new selector position.
