� After that, the all-lighting mode is canceled when any main unit's key is pressed. The normal display obtained when the selector is set to TUNER then appears. (3) Others � The AMP test mode is not terminated even if the selector is set to positions other than TUNER. � In the AMP test mode, the muting during mode selection is not controlled. However, the operation during the power-on sequence is the same as the normal operation. � The SP protection operation is also the same as the normal operation. � In the AMP test mode using main unit's keys, the keys below provide a special operation according to the position where the selector is set. The main unit's keys except described below and the rotary encoder provide the normal operation. (4) When selector is set to TUNER Key EX. BASS key N.B. key ENTER key Operation Increments the P.CALL every time this key is pressed. Decrement the P.CALL every time this key is pressed. Selects the display cyclically in the order below every time this key is pressed.

2. TEST MODE
2-1. Initializing
The system is initialized when the power is turned on while pressing the POWER key. (1) Contents of operation � All the functions are initialized.

2-2. AMP test mode using main unit's keys
2-2-1. Entering the AMP test mode � Turn on the power while pressing the BAND key. 2-2-2. Canceling the AMP test mode � By turning off the power, the system is initialized and the test mode is canceled. 2-2-3. Contents of AMP test mode (1) Automatic POWER ON � The POWER ON state is entered whenever the power is turned on while pressing the BAND key. All functions are then initialized and activated in the all-lighting mode. � Sub-clock oscillation diagnosis function The oscillation diagnosis (existence of oscillation and measurement of period) of a sub-clock is performed before the test mode is entered. If the diagnosis result is OK, the system enters the test mode. If the diagnosis result is NG, the oscillation of the subclock is diagnosed again. If the result is OK, the system enters the test mode. If the diagnosis result is continuously NG five times, the system stops with ERR 1 and ERR 2 displayed. (2) All-lighting mode � All the fluorescent display indicators and LED lamps light when the power is turned on while pressing the BAND key.

1 Write data in the unused area of E2PROM, then read the written data. If the read data is the same as the written data, "RAM OK" is displayed in the fluorescent display indicator. If the former is different from the latter, "RAM NG" is displayed. 2 Set the TUNER ATT to OFF and display the S level in hexadecimal when the ENTER key is pressed. ("ATT OFF **" is displayed in the fluorescent display indicator.) 3 Set the TUNER ATT to ON and display the S level in hexadecimal when the ENTER key is pressed. ("ATT ON **" is displayed in the fluorescent display indicator.) * The special display using the ENTER key is continued until the next operation is carried out. (**: S LEVEL) When keys other than ENTER are pressed in items 1 to 3 above, the TUNER ATT is set to OFF and the normal display appears. The operation corresponding to the key that has been pressed is performed in this case. (5) When selector is set to positions other than TUNER [ENTER key] Every time this key is pressed, master VOLUME level is selected cyclically. INITIALIZE level ìî MAX î MID î MIN ì
Value of Master VOLUME MAX MID MIN INITIALIZE Press the ENTER key. 86 40 1 7
