BOUT ATTERY ACKS AND HARGERS
The Model 8664 and 8665 endpoints require a charged battery pack to operate. The
Nickel Metal Hydride (NiMH) rechargeable battery pack will need to be charged peri-
odically. 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 10).
When the charge on the battery pack is low, the battery icon ( ) is displayed. 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:
If you attempt to remove and replace your endpoint's battery pack while on a
call, the call will be dropped.
To remove and replace the battery pack on the Model 8664:
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:
Press both battery release buttons to release the battery. The battery pack releases out-
ward and you can remove it from the endpoint. To replace the battery pack, slide it
straight into the cavity until it snaps into place.
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.
You can charge the endpoint's battery pack using a desktop charger (Models 8664 and
8665) or the gang charger (Model 8665). Both the desktop charger and gang charger
require approximately one and one half to two hours to charge the battery pack com-
pletely.
