Uniden BT230 ユーザーズマニュアル

15

The headset can be connected only to devices that support the Bluetooth headset or hands-free profile. It is 

not compatible with standard cordless phones.

With average use, the battery should provide about  hours of talk time and  days of standby time. If a 

battery is new or left unused for a long time, it can have reduced capacity the first few times you use it. For 

maximum battery life, keep the 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 changes 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 charge the battery.

The most common cause of noise or static on any wireless device is interference. Bluetooth devices operate in 

the ISM band (2.02 GHz ~ 2.0 GHz); any equipment operating in this frequency range might interfere with 

the headset. Some common sources of interference in this range are

Equipment that uses microwaves, especially microwave ovens

Wireless LAN equipment or WiFi connections

Other Bluetooth devices or computers

Certain cordless telephones

Certain medical equipment and appliances

If you have problems with static during calls, look for one of these interference sources. Try moving away from 

the suspected source.
