3-1 Channel Space Selector in Broadcasting setting
1. Push the BAND key for 2 seconds in the standby mode. 2. Display shows "F100/A10kHz" or "F50/A9kHz" blinkingly for 5 seconds. 3. Turn the VOLUME knob (Encoder) to choose your channel space. 4. Push the BAND key to memorize the channel space to E2P ROM. Note : Channel space will be set by the data from E2P ROM if reconnect the power cord.. Channel space will be set by the destination data from E2P ROM if backup data damaged.
3 E2P ROM check (E, T, Q, M, V type) Check the reading data and the writing data of the E2P ROM after setting the test mode. Display shows blank if the reading and writing data is the same. Display shows "&" if the different. Data (FM 50kHz, AM 9kHz, De-emphasis 50us) will be written to E2P ROM if the unit for M and V type.
4-4 ACTIVE CONTENTS
1 The mute control is not activated when the mode is switched. 2 The test mode will be terminated by plugging it off the power source or by initializing it, when all the settings will be initialized. 3 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 (5. contents). 4 Channel space will be no change if set channel space in the reset mode.
4. TEST MODE
4-1 SETTING
Turn the power ON while pressing the [BAND] key.
4-2 CANCEL
Unplug the AC power cord from an AC power wall outlet.
4-3 STARTING ACTIVE CONTENTS
1 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. 3 All lighting mode is canceled when any main unit's keys are pressed. The normal display obtained when the selector is set to TUNER then appears.
