6. Battery and fuse replacement

If the sign " " 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 one.
Fuse rarely needs replacement and blows usually as a result of the operator's error. Open the case as mentioned
above and take the PCB assembly out from the case. Replace the blown fuse with ratings specified.
