Using the phone during a power failure
During a power failure, you cannot make or receive calls. When power
returns, reset the date and time. Other settings and memory will return as
they were before the power failure.
We recommend that you install the 6F22/6LR61 9V battery (not supplied)
into the phone.
When you install the 6F22/6LR61 9V battery (not supplied) into
the phone
During a power failure, you can make or receive calls. However, the
speakerphone does not function. To make a call, you must press the line
button after picking up the handset, and to receive a call, press the line
button which is flashing after picking up the handset.
The phone can be used for about 30 minutes continuously.
When making a call, you can only use the dialing keys.
During a power failure, “POWER FAILURE” appears on the display.
In the following cases, the battery has been exhausted so it needs to be
replaced.
• When calls cut out during a conversation.
• When the line button does not light up or goes off quickly even if the line
button is pressed after picking up the handset.
• When the display of “POWER FAILURE” becomes weak
• A clicking noise may be heard from the phone
Notes
• You cannot operate the phone other than for making or receiving calls.
• If the AC adaptor is pulled out from the AC outlet when the battery is still inside
the phone, the battery will discharge even if the phone is not being used. Remove
the battery when unplugging the phone for a long time in order to avoid battery
discharge and damage to the phone from battery leakage.
• If there is a power failure during a call with intercom, page, and all page, the call
will be disconnected. When transferring a call, outside call will remain on hold
even in the case of a power failure, so you can return to the outside call.
Tip
If there is a power failure during an outside call, the call may be continued, but the
handset volume and speakerphone volume can not be adjusted.
