6. MAINTENANCE
The following instructions should be performed by the qualified
personnel only in order to avoid electrical shock. Do not perform any
servicing other than the operating instructions unless you are qualified to
do so.
6-1. Line fuse replacement
If the fuse is blown, the instrument would not work. Try to determine
and correct the cause of the blown fuse. The input power fuse is
located within the instrument in a fuse clip. When replacement is
required, install (T0.3A 100V/120V), (T0.2A, 220V/240V) as
indicated on the rear plate.
WARNING: For continued fire protection. Replace fuse
only with the specified type and rating, and disconnect
the power cord before replacing fuse.
6-2. Cleaning
Clean the front panel and case with denatured alcohol or a mild solution
of detergent and water. Do not use aromatic hydrocarbons or chlorinated
solvents because they will react with the plastic materials of the
instrument.
