Alignment
ALIGNMENT-2
Alignment Preparation & Precautions
A 100-W RF dummy load and in-line wattmeter
must be connected to the main antenna jack in all
procedures that call for transmission; alignment
is not possible with an antenna. After complet
-
ing one step, read the next step to see if the same
test equipment is required. If not, remove the test
equipment (except dummy load and wattmeter,
if connected) before proceeding. Correct align
-
ment requires the transceiver and test equipment
be maintained at a constant ambient temperature
between 68 ~ 86 °F (20 ~ 30 °C). When the trans-
ceiver is brought into the shop from hot or cold air,
it should be allowed some time to come to room
temperature before alignment. Whenever possible,
alignments should be made with oscillator shields
and circuit boards firmly affixed in place. Also, the
test equipment must be thoroughly warmed up be
-
fore beginning.
Note:
Signal levels in dB referred to in the alignment
procedure are based on 0 dBμ=0.5 μV (closed circuit).
Internal System Alignment Routine
This uses a programmed routine in the transceiver
which simplifies many previously complex discrete
component settings and adjustments with digital
-
ly-controlled settings via Microphone buttons.
To enter the Alignment mode:
1.
Connect the PANEL-UNIT to
TX-MAIN-UNIT
and RX-MAIN-UNIT.
2.
Press and hold in the
