The frequency of 98.3MHz is received when the [4] key is

pressed in the TUNER FM mode.

TUNER Setup adjustment mode speciﬁ cation

●

1. Use [FM] / [AM] key to select TUNER band.

2. Press and hold [ ] key for 2 seconds to enter TUNER

adjustment mode. At the same time, set FM receive fre-

quency to 98.3 MHz for K / M / E type and 83.0 MHz for

J type.

3. Use [FM] / [AM] key to change between the adjustment

items.
