2. Whenever the amplifier may be put into operation, a
heat sink should be mounted. ICs and transistors
may be damaged if the amplifier should be put into
operation without mounting any heat sink.

7. GENERAL INFORMATION
7.1 DIAGNOSIS
7.1.1 SERVICE MODE
1. Entering the mode
Input "H" to the SMODE terminal when the microcomputer resets.
(Set the RESET terminal to "L," while inputting "H" to the SMODE terminal.)
2. Terminating the mode
Set ACC (accessories) to OFF.
3. Valid keys in the mode
Keys valid for always : POWER, MODE (REMOTE CONTROL UNIT)
: EJECT (HEAD UNIT)
Keys valid for POWER ON : MUTE, VOL UP/DOWN (REMOTE CONTROL UNIT)
TAPE : PROG, APS+/-, FF/REW (REMOTE CONTROL UNIT)
: PROG, RPT, SCAN, DOLBY (HEAD UNIT)
TUNER : UP/DOWN (REMOTE CONTROL UNIT)
In Service mode, only the keys listed above are valid. The analog switch is switched to output audio from an
internal source.
Note : If a navigator or display is connected to the system in this state, the connected equipment does not operate
normally, even though it appears as if operating. Be sure to set ACC to OFF to terminate Service mode, then
connect the equipment.
