1. Conditions according to the destination 
TUNER destination table
2. Contents of tuner preset memory
• Sub-clock oscillation diagnosis function The oscillation
diagnosis(existence oscillation and measurement of peri-
od) of a sub-clock is performed before the test mode is
entered. If the diagnosis result is OK, the system is
entered the test mode.
If the diagnosis result is NG, the oscillation of the sub-
clock diagnosed again. If the result is OK, the system
enters the test mode. If the diagnosis result is continuous-
ly NG 5 times, the system stops with ERR1 and ERR2
displayed.3-5 Tuner test mode
(When selector is set to TUNER.)• P.CALL of preset channel.
• S level indication.
Set the TUNER ATT to ON/OFF and display the S level in
hexadecimal when the [PTY] key is pressed.
• Indication of FL for TA NEWS  and TIMER.3-6 AMP test mode
(When the selector is set to positions other then TUNER.)
During the test mode, it can be operated in a special
manner that is different from an ordinary operation by
using the keys on the remote control or the main body,
specifically as shown in the following table.

3. Test mode3-1 Entering the test mode• Turn on the power while pressing the [OPEN/CLOSE] key.
• The test mode gets started while the power is turned on
after that,all the FLs will light up and the panel opens.
• Sub-clock oscillation diagnosis function is entered by
pressing the [DIGITAL REC MODE] key in the all FL light-
ing mode.3-2 Canceling the test mode
The system is initialized and the test mode is canceled
when the AC power is turned off. 
3-3 Initializing
The system is initialized  when the power is turned on
while pressing the [ON STANDBY] key.
3-4 Contents of the test mode• Key operation in all FL lighting mode.
• All FL lighting off mode.
KEYS OPERATION
All FL lighting off.
Normal indication.
KEYS OPERATION
[AUTO] Green LED lights on.
[A.MEMO] Red LED lights on.
