ABOUT BATTERY PACKS AND CHARGERS
The Model 8664, 8665, and 8668 endpoints require a charged battery pack to operate.
The Nickel Metal Hydride (NiMH) rechargeable battery pack will need to be charged
periodically. A charged battery pack provides four hours of talk time or 80 hours of
idle time. To save battery power, it is recommended that you place the endpoint in
idle mode at the end of every call (see page 12).
The battery icon indicates the amount of charge remaining in the battery pack. The
level indications are approximations of the remaining battery pack life. They do not
indicate equal amounts of battery pack Life. When only one level remains, ( )
the battery pack needs to be charged. If you are on a call, you will hear a soft beep
through the earpiece every six seconds. You have 15-30 minutes of battery life left. If
the battery pack is critically low, and you are not on a call, the Low Battery message
is displayed, and a loud beep will sound. When the battery pack is critically low, the
endpoint will not work until the battery pack is charged.
At some point you may need to replace the battery pack for your endpoint.
NOTE: The battery pack can be changed while the call is still in progress. Do not press
End Call. Place call on Hold. Quickly remove the discharged battery and replace with a
charged battery, power on the endpoint, and press Start Call to resume the call in
progress.
To remove and replace the battery pack on the Model 8664 and 8668:
Press down on the latch on the battery pack to release the battery. The battery pack
releases outward and you can remove it from the endpoint. To replace the battery
pack, slide the lip of the battery pack into the bottom of the cavity and push the top of
the battery pack until it snaps into place.
To remove and replace the battery pack on the Model 8665:
Hold the endpoint in one hand with the keypad facing up. Press both battery pack
release buttons (on the left and right sides of the endpoint) at the same time. The bat-
tery pack will release downward. You may catch it with the palm of your other hand.
If the battery pack does not release, gently shake the endpoint while pressing both
release buttons. Do not pry.
NOTE: Improper disposal of battery packs can damage the environment. Contact your
system administrator for instructions on how to recycle or properly dispose of used bat-
tery packs.
