4.  TROUBLESHOOTING

Before starting any repair work, strictly obey the following instructions.

 CAUTION:

• When replacing parts, be sure to turn the main switch OFF and unplug the power-cord plug

from the outlet.

Notes:

• Be sure to output a dial list and a system function list and keep them until the troubleshooting

is completed so that if the user’s set data is lost it can be re-entered.

• Before turning the main switch OFF, be sure to confirm that the residual memory is 100%

and no memory reception documents exist. If there is such a document , it will be lost if the

service activity requires the battery backup to be unplugged.

the photosensitive material from deterioration by exposure to light.
