General Information You can use the travel kit while it is recharging. Bluetooth wireless devices have a maximum range of 30 feet (10 m); the actual range will vary depending on current conditions (obstacles, battery power, interference, etc.). The travel kit can be connected only to devices that support the Bluetooth travel kit or hands-free profile. This product is not compatible with standard cordless phones. Battery life With average use, the battery should provide about 12 hours of talk time and 10 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 travel kit triggers a low battery alert: you'll hear a melody every 20 seconds, and the display shows Low Battery. When the battery no longer has enough charge to operate the travel kit, the travel kit will power off; you won't be able to turn it back on until you connect the charger or charge the battery.
