This chapter provides information necessary for keeping your unit in good 
working order and remedying simple problems. 

Hazardous voltage which can
cause electrical shock exists
inside the equipment. Only 
qualified personnel should 
work inside the equipment.

Regular maintenance is important for optimum performance. A maintenance 
program should be established and should at least include the items shown in 
the table below. 

Display unit 
connectors 

Check for tight connection. 

Tighten loosened 
connectors. 

LCD 

The LCD will, in time, accumulate 
a coating of dust which tends to 
dim the picture. Wipe LCD lightly 
with soft cloth to remove dust. 

Do not use chemical 
cleaners to clean any part of 
the display unit; they can 
remove paint and markings. 

Ground terminal 

Check for tight connection and 
corrosion. 

Clean or replace ground 
wire as necessary. 

 
 

A lithium battery (Type CR2450-F2 ST2, Code No. 000-133-495) fitted on a 
circuit board inside the display unit preserves data when the equipment is turned 
off, and its life is about three years. When its voltage is low the battery icon ( ) 
appears at the top of the display. When the icon appears, contact your dealer to 
request replacement of the battery.
