· When entered in the TEST MODE, this set provides the Overall Adjustment mode which allows CD and MO discs to be automatically adjusted. In the Overall Adjustment mode, performs adjustments in sequence automatically, and displays the faulty location if any fault is found. In the Manual mode, selected adjustments can be performed automatically. · Operations in the Overall Adjustment mode can be performed either via the main unit, or the keys of a remote control unit. Note that this device does not include a remote control unit. Therefore, since no connection terminals for a remote control are provided either, a connection device must be used in order to allow a suitable remote control unit to be connected. Connection Following parts are required Remote commander: RM-MZ2N (1-418-493-71) After RM-MZE1 applicable to 2.4V (Not applicable to remote commanders before RM-MZE1). Jack: 7 poles jack for phones/remote commander (1-793-288-61)

The remote control display varies with the type of remote control unit used. (Example shown: RM-MC10L)
The Manual mode is designed to perform adjustments and operational checks on the set's operation according to each individual function. Usually, no adjustments are made in this mode. However, the Manual mode is used to clear the memory before performing automatic adjustments in the Overall Adjustment mode. * Manual mode operation can only be performed via the remote control unit. Use the connection tool to connect the remote control unit. The display of the main unit shows "Adj". 4-4-2. How to set the Manual mode 1. Set the TEST MODE and press + key to set the Manual mode.

· The current display is retained as long as either the PLAY MODE/DISPLAY key on the main unit or the PLAY MODE key on the remote control unit is pressed and held. 4-2-3. How to release the TEST MODE When method 1 was used: Turn off the power and open the solder bridge on BP801 on the main board. Note: The solder should be removed clean. The remaining solder may make a short with the chassis and other part. When method 2 or 3 was used: Turn off the power. Note: If electrical adjustment (see page 8) has not been finished completely, always start in the test mode. (The set cannot start in normal mode)
