[Setting the unit to Test mode]
You can set the unit to Test mode with the following procedure:
1. Turn off the power.
2. Short-circuit the pattern for Test mode.
3. Turn on the power.
(When the unit enters Test mode, RAM information of the
mechanism control is cleared.)
If Test mode is set correctly, displays different from those in ordinary
power-up state are obtained. (All the FL indicators light, and REC
LED lights in amber. (For PDR-509, REC LED lights in red. ) )
If the displays are the same as those in the normal mode, Test mode
may not have been set correctly. Repeat steps 1 to 3 above.
Caution: Before setting the unit to Test mode, be sure to set the
INPUT selector to ANALOG.
If the selector is not set to ANALOG, malfunctions may
occur in Adjustment mode.
