Battery Backup – System Memory
The battery on the CD-CP00-US retains the Clock/Calendar and Last Number Redial
(LNR) buffers for each station when the CD-CP00-US encounters a power loss. With
a fully charged battery, the settings are retained for approximately three years.
The system programmed memory (Customer Database) is stored in Nonvolatile
Memory and can be erased only by performing a First Initialization.

For additional storage time, the database and Caller ID History can be copied to the Compact
Flash card on the CD-CP00-US.
Battery Backup – System Power
A built-in battery provides complete system operating power for approximately 30
minutes during commercial power outages. When optional (locally provided) batteries
are connected and fully charged, full system operation can be maintained for an
extended time. Actual time depends on system configuration, traffic conditions, and
the battery capacity.
Call Appearance (CAP) Keys
This feature automatically places an outside call on a Call Appearance key when the
system is operated as a hybrid (Multifunction) system. These keys can be assigned
on any multiline terminal or the same key can appear on multiple terminals. This
feature allows efficient call handling when numerous CO calls are received and a
limited number of CO line key appearances are available.
The use of monitoring, recording, or listening devices to eavesdrop,
monitor, retrieve, or record telephone conversation or other sound
activities, whether or not contemporaneous with transmission, may
be illegal in certain circumstances under federal or state laws.
Legal advice should be sought prior to implementing any practice
that monitors or records any telephone conversation. Some federal
and state laws require some form of notification to all parties to a
telephone conversation, such as using a beep tone or other
notification methods or requiring the consent of all parties to the
telephone conversation, prior to monitoring or recording the
telephone conversation. Some of these laws incorporate strict
penalties.
