● How to enter the test mode
Press and hold the [1] and [3] keys and reset.
(While ”----” is being displayed, power can be ON for 30
minutes.)
●How to clear the test mode
Reset, momentary power down, ACC OFF, Power OFF,
detach the panel.

• SOURCE SELECT shall be “2”.
●Specification of the test mode for tuner source
The frequency of 98.3MHz is received when the [4] key is
pressed in the TUNER FM mode.
●TUNER Setup adjustment mode specification
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.

is no Soft Mute adjustment for AM band.
4. Proceed with the following steps for every adjustment
item:
Soft Mute Adjustment
∗This item exists only in TUNER FM. Make adjustment
under the condition when VOLUME=30 and LOUD is
OFF.

shown in “x”.
a. Use [ ] / [ ] key to set the value between 0 (18dBu)
and F (36dBu).
b. After the completion of the adjustment, press and hold
[] key for 2 seconds to start writing the adjustment
values in E2PROM. At the successful completion of
the writing, “EP_WRITE” is displayed

Press [AUTO] / [TI] key briefly to change between Lo-
cal Seek ON and OFF.
b. Press and hold [ ] key for 2 seconds to make the cur-
rent receive level to be the seek stop level in order to
start writing the adjustment values in E2PROM. At the
successful completion of the writing, “EP_WRITE” is
displayed. (In this step, use Local Seek ON/OFF setup
to change the destination of the writing.)

In K/M/E type, the key keeps functioning downwards
after the level becomes 0.00V but in the meantime
the level will become 0.00V as it is displayed.
c. Press and hold [ ] key for 2 seconds to make the volt-
age that is adjusted in the above step to be the seek

and that the content of the PS is “RDS_TEST”, force to
OFF the P-CON terminal. ( The symbol, “_” indicates the
blank. )
→ Make this as the process dedicated for the test mode.
P-CON is recovered by Power OFF→ON.
●Special display in tuner mode
Error is found in front-end, etc. if indications below are
displayed while in tuner mode.
• “TNE2P_NG”……E2PROM (inside front–end) values are
still default (not determined)
