[P.CALL] key, the POWER will turn ON and all function
will be at the initial setting.
ALL LED ON mode
• When the AC power cord is plugged while pressing the
[P.CALL] key, all the LEDs will turn ON. Any key operation on the main unit thereafter will return the LEDs to normal.
Main unit key validity check
• Whether the main unit's keys are operable (valid) can be
checked. Regarding the keys whose display does not
change when they are used, their display will be made to
change.

1-2. Test mode with serial communications
Refer to the test mode serial code table.
a) Setting procedure
• Plug the AC power cord and enter the TEST ON code.
8 bit serial communications: 71H
16 bit serial communications: 0C2FFH
b) Cancellation
• Enter the TEST OFF code (0CFEH) or unplug the AC
power cord.
c) Description
Other operations during the serial test mode
• The main unit's keys will be effective.
• The serial test code can be received even within 1 second
of POWER ON / OFF.
Required operations for the serial test mode
• The serial code for the serial test mode can be used to
check the operation of all circuits.
• The code entered during the serial test mode will become
valid regardless of the display mode.
• The following functions are available in the serial test
mode.

ON/OFF
• The MUTE signal is not output. This is for reducing the
input-output switching time during the measurement.
• When a valid serial code for the test mode is received, the
code identical to the code entered will be output.
• For checking the MUTE operation, MUTE has specific
codes.
MUTE ON/OFF
• To switch cyclically, enter the individual serial code. For
example for AUTO STEREO / MONO, enter the two
