About Cordless Terminals
Before you use the Bluetooth
®
handset for the first time or using the handset after it has been
left out of use for a long time, charge it for at least 5 hours. (Full charging takes about 16
hours to complete.) A fully charged handset will allow you to talk for about 8 hours
continuously and stand by for about 30 hours if low-power mode is enabled or for about 15
hours if low-power mode is disabled.
The remaining battery voltage icon appearing in the LCD screen, coupled by the incoming
call/charging lamp and an alarm tone, alerts you to the remaining battery voltage of the
Bluetooth
®
handset. The table below describes how these indications appear depending on
the remaining battery voltage of the handset.
