4.1.1 Preparations for checking/tuning the transceiver
Before attempting to check/tune the transceiver, connect the unit
to a suitable power supply.
Whenever the transmitter is turned on, the unit must be
connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a 4ohm
dummy load and connected to an AC voltmeter and an audio
distortion meter or a SINAD measurement meter at all times
during checking/tuning.
