Checking the battery status
When the headset is paired and connected to a phone, press and
hold the Power/Send/End button for about two seconds.
• If the indicator flashes green once, the battery level is over half of
the battery capacity.
• If the indicator flashes orange once, the battery level is less than
half, but has more than one hour of talk time.
• If the indicator flashes red once, the battery level is less than one
hour of talk time.
Resetting the headset (hardware reset)
To reset the headset (hardware reset):
• Press and hold the Power/Send/End button and connect the charger
at the same time. The headset is turned off and reset.
Note: You should only use the reset function when the headset operates unusually.
When you reset the headset, pairing information is not erased.
Maintaining
• Do not store the headset in cold areas. When the headset returns
to normal temperature, moisture can form inside the headset and
damage electronic circuit boards.
• Do not drop, knock, or shake the headset. Rough handling can
break internal circuit boards and fine mechanics.
• Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean the headset.
• Do not paint the headset. Paint can clog the moving parts and
prevent correct operation.
