6.0 HANDSET MAINTENANCE:
The handset is designed to require minimal maintenance from the user. If the handset is dirty,
use a 1” paint brush or similar brush to clean loose dust and debris from your handset before
wiping clean with a damp cloth taking care not to scratch the display. Do not use chemical or
abrasive cleaners as this may result in damage to the chassis.
If using the alkaline battery pack the alkaline batteries may be replaced by the user. To open
the battery pack, depress the orange tab and slide the battery cover off. Remove and replace
the six alkaline cells. Be sure to follow the diagram for the positive and negative terminals. Use
only standard 1.5V AA size alkaline cells. Slide the orange cover back onto the pack until the
catch clicks, locking it into place.
Never disassemble the handset or IS battery pack. Doing so will void your warranty. If your
handset or its battery pack is damaged do not use it.
