TEST MODE AND ADJUSTMENT

0TEST MODE AND ADJUSTMENT

1.

To enter test mode

While holding the key and preset IE] key, reset
the unit.

All indication segments are ON at the beginning of
test mode.

To release test mode
Simply reset the unit.
(NOTE):
The test mode is not canceled by ACO OFF,
power OFF, momentary power down or the
panel detaching.

FM signal meter voltage adjustment

1) Enter test mode.

2) Receive 98.1 MHz with the SG and set the ANT
input level to 35dBp. The modulation should be
off during this.

3) While holding preset key, press and hold
preset E! key for a few seconds.

4) ADJ OK" is displayed if the adjustment is OK
and "ADJ NG" is displayed if it is not good.

. AM SD voltage writing

1) Enter test mode.

2) Receive 999kHz or 1000kHz with the SG and
set the ANT input level to 35dBp.
The modulation should be oh during this.

3) While holding preset key, press and hold
preset [El key for a few seconds to write the SD
voltage.

5. CD receiver test mode specification

Pressing the El key jumps between tracks in the
following order.
No.9 -> No.15 -> No.10 -> No.11 -> No.12
-> No.13 -> No.14 -> No.19 (Same as the
biginning)
Pressing the E key jumps to the previous track
to the track being played.

. Audio adjustments

0 The volume is set to -10dB (which is shown as
30).

- The BASS/TREBLE and BALANCE/FADER
controls can be set to the full boost/full cut and full
front/full rear respectivily by pressing the /
keys.

- The high pass filter can be set to 220Hz/through
by pressing the / keys.

0 Note that, however, the non-fader control is varied
in +1dB/ ~1dB steps by pressing the / keys.
