ALIGNMENT INSTRUCTIONS
1. ALIGNMENT FOR MW SENSITIVITY
a. Required Instruments:
RF Signal Generator
ACV Meter
Oscilloscope
b. Alignment Procedure
Mode Adjustment Procedure
(1) Press the power button to turn on the radio.
(2) Connect the input terminal of MW ANTENNA to the RF output of RF signal generator.
(3) Connect the Line out terminal of radio to the input of ACV meter and oscilloscope.
T301
(4) Tune the MW frequency to 1710KHz and adjust the TC301 to make the Line out Level
MW
is maximum.
TC301
(5) Tune the MW frequency to 520KHz and adjust the TC301 to make the Line out Level
is maximum.
(6) Repeat the step 4 and 5 to make the MW sensitivity is optimum.
