4-2. SETTING THE TEST MODE
4-2-1. How to set the TEST MODE
To set the TEST MODE, three methods are available.
1 Solder bridge and short BP801 (TEST) on the main board.
Then turn on the power.
4-1. GENERAL
•
When entered in the TEST MODE, this set provides the Overall
Adjustment mode which allows CD and MO discs to be auto-
matically 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 ad-
justments 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.
