ELECTRICAL ADJUSTMENTS
Note: As a FM/AM tuner (TU1) is difficult to repair if faulty, replace it
with new one.
¢ FM Signal Level Display Adjustment (GX315, GX415)
Setting:
FM RF signal
generator
Carrier frequency: 98 MHz
Modulation: 1 kHz
75 kHz dev. FM ANTENNA 75Q
(100%) terminal
Procedure:
1. Tune the set to 98 MHz.
2. Apply 80 dBy, 98 MHz signal to the FM antenna terminal.
3. Press the DISPLAY button of the unit to indicate the signal
level.
4. Adjust RV1 so that signal level indication is changed from
[SIG 71 dB ]t0 [SIG 75 «B]
Apply 81 dBu, 98 MHz signal to the FM antenna terminal.
6. Make sure that the signal level indication is | SIG7SadB | If
not, repeat step 2 to 6.
