2-12 MH120 Wireless Telephone
Mobile Handset 120 and Desktop Charger/Gang Charger User Guide - Revision 1
Working with Battery Packs
The Wireless Telephone’s Battery Pack must be recharged periodically.
The Nickel Metal Hydride (NiMH) rechargeable Wireless Telephone
Battery Pack gives you four hours of talk time or 80 hours of stand-by
time.
Low Battery Indicator
When the Wireless Telephone battery is running out of power a low
battery icon displays. If the Wireless Telephone is in use, a soft beep
sounds through the earpiece every six seconds indicating that the user
has 15-30 minutes of battery life remaining.
If the Wireless Telephone is not in use when the battery begins to run
out of power, the low battery icon displays. If the battery is not
recharged and becomes critically low, a Low Battery message displays
and a loud beep sounds. These occur when the user is not in a call. The
Wireless Telephone will not work until the Battery Pack is recharged.
Removing and Replacing Battery Packs
Use the following steps to remove and replace MH120 Battery Packs.
Step 1 Press both battery release buttons to remove the Battery Pack. The
Battery Pack releases outward.
Step 2 Slide the Battery Pack straight into the cavity to replace the Battery Pack.
You should not have to force it against the Wireless Telephone.
NOTE
Stand-by time is when the phone is turned on, but not in an active call.
CAUTION
Be careful not to short-circuit the battery contacts on the Battery Pack. Batteries can
be short-circuited if metal objects such as coins, keys or paper clips cause a direct
connection of the battery terminals. Shorting the contacts can cause permanent
damage.
