Replacing the Ni-Cd Batteries
The service life of Ni-Cd batteries is reduced if they are used repeatedly, even if they
are completely charged. The interval between battery replacement differs depending on
the operating conditions, but you should replace them approximately every two years or
after recharging them 500 times. Battery pack replacement must be done as described
on page 18.
Replacing the Backlighting EL
The EL for backlighting is consumable. The EL can be used continuously for
approximately 5000 hours before its brightness falls by half. It is recommended that the
EL be replaced after approximately 5000 hours of use (i.e., about 6 months at 24-hour
continuous operation). It is not possible for user personnel to replace the EL, so please
contact your nearest representative.
Replacing the Fuse
WARNING
• The fuse used must be of the specified rating in order to
minimize the risk of a fire hazard. Never use a fuse of any other
rating and never short-circuit the fuse holder to bypass the fuse.
• Before replacing the fuse, be sure to turn the power switch off,
remove the connections from each input and output terminal and
remove the power cord from the AC outlet.
Fuse Position and Replacement Method
The current input terminal accommodates a built-in fuse. A fuse is contained in the fuse
holder as shown below. To replace the fuse, turn the fuse holder counterclockwise with
your fingers to remove it, and then replace the fuse with a new one.
