Tips on Extending Battery Pack Life
Battery Memory Effect
All rechargeable nickel cadmium batteries can develop a “memory” (reduced charge capacity)
caused by repeated charge and discharge cycles. Batteries that have developed this effect do
not operate to their fullest capacity.
➤ To avoid memory effect
➤ Operate the unit until the battery pack is completely discharged before recharging. For
example, use the handset off the base all day. Only replace the handset on the base at night
after a full day of use. Do not “top off” the charge after using the battery for a short time.
➤ To erase memory effect
➤ Operate the unit until the battery pack is completely discharged, then recharge it fully.
Repeat this process at least three times.
LCD Low Battery Indicator
When the battery pack in the handset is low and needs to be charged
you see this message on the display and the handset beeps.
Low Battery Symptoms
To restore your battery capacity, return the handset to the base unit for charging or replace the
handset battery pack with another charged one.
