The CDM-810 Battery (AX-401)
(Optional Accessory)
NOTE: The following section applies only if a battery is supplied
with your CDM-810; or you purchase a battery in the future.
A NiCd battery pack will provide backup power in the event of an
AC power outage. Under normal usage conditions your battery
can be used for up to four years. The battery allows you to place
or receive a call if AC power is temporarily lost (known as backup
time). The actual backup time will vary with the age of the battery,
how many times it has been charged and discharged, and
distance from the telephone service provider’s RF transmit-
ter/receiver.
When to Replace the Battery
You should consider replacing the battery when any of the follow-
ing occurs:
•
The battery is older than four years.
Testing the Battery Condition
Condition: The CDM-810’s battery can no longer provide 16
hours or more of standby-time following a full charge (a battery
will reach a near-full charge condition after the AC power has
been on for 36 continuous hours).
Battery Replacement
Before installation, make sure that you have purchased a new
battery of the correct model/type. See page 9 for instructions.
