■ 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 con-
nected 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
times during tuning.
■ Transceiver tuning
(To place transceiver in tuning mode)
Press [S] key, now in tuning mode. Use [B] key to write
tuning data through tuning modes, and [ ]/[ ] to adjust tun-
ing requirements (1 to 256 appears on LCD).
Use [C] key to select the adjustment item through tuning
modes. Use [A] key to adjust 3 or 5 reference level adjust-
ments, and use [■ ] key to switch between Wide/Narrow.
Channel appears on LCD. Set channel according to tuning
