If a Power Cut Occurs
The MultiPASS L90 includes a built-in lithium battery and a backup battery for
use in case power to the unit is cut off.
The lithium battery has a life of about five years and will save the unit's
registered data for one-touch speed dialling, coded speed dialling, group dialling,
etc.
However, the backup battery will only save the documents stored in memory for
approximately one hour. If the power failure lasts longer than an hour, the stored
documents will be lost (in this case, the unit automatically prints a list of the lost
documents when power is restored).
During a Power Failure
While power is off, you can only use the unit to receive telephone calls. You can
not make calls, nor send or receive faxes. With some extension telephones,
however, you may be able to make calls.
Memory Backup Function
To make the best use of the unit's memory backup, avoid disconnecting the
power. The backup battery recharges while the unit is powered on, and takes 15
minutes to recharge fully.
If documents are stored in memory, do not disconnect the power unless
absolutely necessary. If you do disconnect it, try to reconnect it within an hour, or
data may be lost.
