Battery Life - Uniden BT112 User Manual

•
The headset can be connected only to devices that support the
Bluetooth headset or hands-free profile. This product is not compatible
with standard cordless phones.

Battery life

With average use, the battery should provide about 5 hours of talk time
and 100 hours (4 days) days of standby time. A battery that is new or left
unused for long periods of time can have reduced capacity the first few
times it is used. For maximum battery life, keep your battery charged.
•
When the battery only has enough charge for about 30 minutes of talk
time, the headset triggers a low battery alert: you'll hear a periodic beep.
•
When the battery no longer has enough charge to operate the headset,
the headset will power off; you won't be able to turn it back on until you
connect the charger or charge the battery.
