Settings for
Receive Tests
For receive tests set the switches on the test unit as follows:
■ HOOK switch : “HOOK OFF”
■ MODE switch : “RX”
■ AUDIO IN switch : “OFF”
■ AUDIO OUT switch: “SPEAKER” or “LOAD”
In the last-named case, with the switch in the “S
PEAKER” position, the
received audio is output from the test unit’s speaker. In the “L
OAD”
position a 16 Ω load is switched into the circuit in place of the test unit’s
speaker. Note, however, that the
AUDIO OUT switch has no effect on the
radio’s speaker.
Settings for
Transmit Tests
For transmit tests set the switches on the test unit as follows:
■ HOOK switch : “HOOK OFF”
■ MODE switch : “RX” initially
■ AUDIO IN switch : “MIC AUDIO”
■ AUDIO OUT switch: (immaterial)
When ready to transmit, set the
MODE switch to the “TX/PTT” position.
This switch functions in the same way as the PTT switch on the
microphone.
