6. BATTERY AND FUSE REPLACEMENT

If the sign "BATT" appears on the LCD display, it indicates that the battery should be replaced.
Remove screws on the back cover and open the case. Replace the exhausted battery with a new
battery.
Fuses rarely need replacement and blow usually as a result of incorrect use. Open the case as
mentioned above and take the Printed Circuit Board assembly out of the case. Replace the blown
fuse with a proper rated fuse below.
WARNING
!
Before attempting to open the open case, be sure that it is disconnected to avoid electric shock
hazard.
For protection against fire, replace fuses only with specified ratings:
