SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power
cord is less than 460 kohms, the unit is defective.
LASER RADIATION
Do not stare into beam or view directly with optical instruments, class 3A laser product.
CAUTION Please heed the points listed below during servicing and inspection.
Heed the cautions! Inspect for safety after servicing!

2 CAUTION IN SERVICING
Initializing RCD-M35DAB/M33
RCD-M35DAB/M33 initialization should be performed when the
µcom, and peripheral parts of µcom are replaced.
1. Switch off the unit and remove the AC cord from the wall out-
let.
2. Hold the following button and MENU/SET button,
and plug the AC cord into the outlet.
Note: All user settings will be lost and this factory setting will
be recovered when this initialization mode.
So make sure to memorize your setting for restoring
after the initialization.
