The test mode is cleared in case of any of the following e v ents: resetting, momentary power down, Acc OFF, P o wer OFF and removal of the panel.

●Initial conditions of the test mode

• Source is STANDBY.

• Displays lights are all turned on.

• The volume is at -10dB (The display is 30).

• Loudness (LOUD) is OFF.

• CRSC is OFF, regardless of whether there are switching functions or not.

• SYSTEM Q is NATURAL (=FLAT).

• BEEP will sound anytime with a short push.

•Auxiliary (AUX) is ON.

• SWPRE is SUB WOOFER (2 PREOUT models).

●RDS automatic measurement

Conventionally, the PS display has been visually checked on the production line. This will be replaced by a new processing. The PS data will be received and the PS contents is to be verified as “RDS_TEST” When this is verified, the P-CON terminal is forced to go OFF. ( In this case, “_” means blank. )

→This will be a dedicated test mode processing.

On the P-CON, when power is turned off once and, then, turned on again, (Power OFF → ON ) the unit will be restarted.
