CJ1W-BAT01
Check whether the battery
has reached its service life.

Service life expectancy
is 5 years at 25°C.
Depending on model
and ambient tempera-
ture.

Replace the battery when its service
life has passed even if a battery
error has not occurred. (Battery life
depends upon the model, and ambi-
ent conditions.) Refer to

tery Replacement

on page 6-6 for

the service life of individual model.

Check whether the
NX-FAN01 Fan Unit has
reached its service life, or
whether it is rotated during
power supply.

Service life expectancy
is 10 years at 55 °C.

Replace the Fan Unit when its ser-
vice life has passed even if the fan
speed has not decreased. Refer to

6-3-3 Fan Unit Used for Replace-
ment

on page 6-11 for the service

life, and

6-3-4 Procedure of Fan Unit

on page 6-12 for how

to replace the Fan Unit.
