that support the Bluetooth headset or hands-

standard cordless phones.
Battery life
With average use, the battery should provide
about 9 hours of talk time and 8 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 15 minutes of talk time, the headset
triggers a low battery alert: you’ll hear a
periodic beep, and the LED changed from blue
to red.
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.
