ADJUSTMENT (MTR)
Antenna adjustment
Use the following adjustment procedure to obtain op-
timum antenna and radio reception sensitivity.
1. Extend the antenna fully.
2. Set the ignition key to ACC.
3. Turn on the radio, and set it to AM reception.
4. Tune in a distant station with a weak signal at
around 1400 kHz. If such a station cannot be
found, use static to make the adjustment.
5. Turn the antenna trimmer adjustment screw to the
left and right to find the maximum sensitivity (of ei-
ther the broadcast or the static).
Note
If there is no change in the sensitivity, either
the tuned signal is too strong, or there is an
antenna malfunction or broken wire.
