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 8
Ω
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 enter tuning mode)
To enter tuning mode, press the [ ] key while the trans-
ceiver is in test mode. Use the [ ] key to write tuning data
through tuning modes, and the [
]/[

requirements (1 to 4096 appears on the LCD).
Use the [
] key to select the adjustment item through
tuning modes. Use the [ ] key to adjust 5 reference level
adjustments, and use the [Side2] key to switch between
