Frequency and Signaling
The transceiver has been adjusted for the frequencies
shown in the following table. When required, re-adjust them
following the adjustment procedure to obtain the frequen-
cies you want in actual operation.

Preparations for Tuning the Transceiver
Before attempting to tune the transceiver, connect the
unit to a suitable power supply.
Whenever the transmitter is tuned, the unit must be con-
nected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a
8Ω dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.
