Panel Tuning Mode
The transceiver is adjusted in this mode.
■ Preparations for tuning the transceiver
Before attempting to tune the transceiver, connect the
unit to a suitable power supply.
Whenever the transmitter is turned, the unit must be
-
connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with
a 4Ω dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
P25/
times during tuning.
