Setting Up Your Headset
Charge the battery
Before using your headset, charge the battery for at least 8 hours.
Charging the battery completely (and keeping it charged) will help you get the longest possible talk and standby time out of the battery.
Use ONLY the power adapter supplied with the headset! Using any other adapter could damage your headset, create a fire hazard, or cause a risk of electric shock!
| Charging the BT108 | Charging the BT109 |
| Connect the adapter to the power connector on the top of the headset, then plug it into a standard 120 volt AC (regular indoor) power outlet. | Connect either adapter to the power connector on the top of the headset. Connect the AC adapter to a standard 120 volt AC (regular indoor) power outlet. Connect the DC adapter to a standard 12 volt DC (regular automobile) power outlet. |
Pair the headset to your Bluetooth phone
Pairing is like "introducing" two Bluetooth devices and giving them permission to connect to each other. If you want to use the headset with more than one phone, you need to pair it with each phone separately. Once a phone and the headset are paired, they can connect automatically whenever they detect each other.
- Make sure the headset is powered off and the power adapter is not connected (you can't use the headset while it's charging).
-
Press and hold Power until the LED flashes alternating red and blue. The headset is in pairing mode and should be visible to other Bluetooth devices.
-
On your phone, start a search for Bluetooth headsets or handsfree devices. (This process may take several seconds, and it will be different for each phone; see your phone's manual for detailed instructions.)
- Your phone should discover a device called a device called a BT108, BT108 headset, BT109, or BT109 headset, When your phone asks if you want to pair with this device, answer yes.
- When your phone prompts you for a PIN code or password to pair with the BT108 or BT109 enter 0000.
- When the headset is paired, the LED turns blue and flashes every 3 seconds. Your phone might display a confirmation message, also.
- Your phone might ask if you want to change the headset's name; generally, you should only change the name if you have more than one BT108 or BT109 headset that you use with this phone.
Connecting to your phone
Most phones connect to the headset as soon as you pair it; if yours won't, turn the headset off and back on. If headset still won't connect, check your phone's owner's manual for additional Bluetooth information.
Once the headset is paired:
Whenever you turn the headset on, it will automatically try to connect to whatever device it was connected to last.
- If the headset loses the connection (e.g., if your phone is out of range), it reconnects automatically. To manually reconnect, press Power.
If the headset goes more than 1 hour with no connection, it automatically turns off.
Using Your Headset
Put your headset on
Insert the ear cushion, then wrap the earhook behind your ear.
Everyone's ear has a sweet spot, a particular angle of the speaker where the audio comes in loud and


clear. Take a few minutes to move the headset around until you find the best angle for the ear cushion.
If you can't find your sweet spot or if the cushion doesn't fit comfortably in your ear, change it to one of the other sizes that came with the headset. Pull the cushion off gently and snap a new one on.
Wearing the headset on your left ear
If you want to wear the headset on your left ear, take the earhook off and turn it over.


Hold the hook at the bottom and gently lift it over the speaker.


Slide it over the speaker and back into place.

Flip the hook over so it faces the other direction.

Available Features
After the headset is connected, you can use the following features:
| Make a call | Just make the call from your mobile phone as usual; your phone should automatically send the call to the headset. If your phone doesn't, press and hold Power for 2 seconds to send the call to the headset manually. |
| Answer a call | While the call is ringing, press Power. |
| Hang up | Press Power. |
| Send a call back to your phone. | During a call, press and hold Power for 2 seconds. The headset sends the call to your phone and disconnects from the phone. |
| Reject an incoming call | Press and hold Power for 2 seconds; when you hear a beep, release the button. |
| Redial the last number | Press and hold Volume Down; when you hear 4 beeps, release the button. |
| Activate voice dialing | With the phone in standby, press Power and release. When you hear a beep, start using your phone's voice commands. (Your phone must support voice dialing, and all commands must be pre-programmed.) |
Muting the microphone
To mute the microphone so the caller can't hear you, press and hold both Volume Up and Volume Down for about one second. The headset beeps periodically to remind you that the microphone is muted. Press and hold the buttons again to turn the microphone back on.
Troubleshooting and Maintenance
If you have problems with the headset, see the suggestions in the table below. If these suggestions don't help, contact customer support (see the cover for contact information).

| I can hear the caller, but the audio is very weak or soft. | - Turning the speaker volume up. - Moving closer to your phone (if you aren’t carrying it). - Adjusting the ear cushion to find your “sweet spot” (see page 6). - Keeping the battery fully charged; As the battery starts to run out, the speaker gets softer. |
General Information
- You cannot use the headset 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 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 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.
Noise or Static on the Headset
The most common cause of noise or static on any wireless device is interference. Bluetooth devices operate in the ISM band (2.402 GHz 2.480 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.
If the noise continues, there may be interference on your phone itself, and any noise in the phone's connection will come through on the
headset, too. Transfer the call to your phone and see if the audio quality improves. If it doesn't, check around for things that might interfere with your phone.
Safety and Handling Information
For maximum product life, do not drop, throw, or crush the headset. Do not expose it to humidity, dust, or temperatures above 125 F.
Cleaning the headset
- If necessary, remove the ear cushion and earhook. Dampen a lint-free cloth with water or a cleaner specially designed for electronics, and gently wipe the headset clean.
- Do not expose this product to liquid (water, alcohol, etc.) or submerse in liquid for any reason.
Avoiding hearing damage
Using any headset or earbud at too high a volume can cause permanent hearing damage. To reduce the risk of hearing damage:
- Set the volume at the minimum level needed to hear in the current environment. If possible, use your headset in quiet surroundings or try to move to an area with less background noise before adjusting the volume.
- Start with the volume at its lowest setting, then gradually increase it until you can hear.
- Turn the volume down before powering off the headset and readjust the volume each time you turn it on.
- If someone next to you can hear the other end of the call through your headset or if your ears hurt or ring when you hang up, the volume is too high.
- The longer your ears are exposed to noise, the greater the risk of damage. Limit calls at higher volumes (or other exposure to loud noise).
- For more information on protecting your hearing, visit the WISE EARS® website (www.nidcd.nih.gov/health/wise/) or consult an audiologist.
