[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.

[Releasing Test mode]

You can release Test mode with the following procedure:

1. Press the STOP key to stop all operations.

2. Turn off the power.
