Setting Up Your Headset
Charge the battery
Before using your headset, charge the battery for at least 2 hours.
Charging the battery completely (and keeping it charged) will help
you get the longest possible talk and standby time out of the battery.
5
Use ONLY the power adapter supplied with the headset! Using any other adapter could
damage your headset, create a re hazard, or cause a risk of electric shock.
1. 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.
The blue LED remains on while the headset is charging.
2. Charging is complete when the blue LED turns o.
The headset beeps every 30 seconds when the battery is low. The headset
may power o if it is not charged within 30 minutes.
Pair the headset to your Bluetooth phone
Pairing is like “introducing” two Bluetooth devices and giving them
permission to connect to each other.
NOTE: The headset goes into Pairing mode automatically the rst time you use it.
1. Make sure the headset is powered o and the power adapter is not
connected (you can’t use the headset while it’s charging).
2. Press and hold MFB for 5 seconds until the blue LED is steady on, then
release it. The headset is in pairing mode and should be visible to other
Bluetooth devices.
6
3. On your phone, start a search for Bluetooth headsets or handsfree
devices. (This process may take several seconds, and it will be dierent
for each phone; see your phone’s manual for detailed instructions.)
4. Your phone should discover a device called BT112 or Headset. If your
phone asks if you want to pair with this device, answer yes.
5. When your phone prompts you for a PIN code or password to pair with
the BT112, enter 0000.
6. When the headset is paired, the LED begins ashing once in 6-second
intervals. Your phone might display a conrmation message, also.
7. 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
BT112 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,
then turn the headset o and back on. If the headset still won’t connect,
check your phone’s owner’s manual for additional Bluetooth information.
Once the headset is paired:
7
• 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 if the phone is back in range within 1 minute.
After 1 minute, you must press MFB to manually reconnect to the phone.
• If the headset loses connection to the phone during a call, the call is
automatically forwarded to the phone. However, the phone setting
determines if the phone will keep the forwarded call or drop it.
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 nd the best
angle for the ear cushion.
8
If you can’t nd your sweet spot or if the cushion doesn’t t comfortably
in your ear, change it to one of the other sizes that came with the headset.
Pull the cushion o 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, slide
the earhook o and turn it over.
Flip the hook over so it faces
the other direction.
Slide it back on headset and back into place.

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 prole. This product is not compatible
with standard cordless phones.
Battery life
With average use, the battery should provide about 5 hours of talk time
and 100 hours (4 days) days of standby time. A battery that is new or left
unused for long periods of time can have reduced capacity the rst few
times it is used. For maximum battery life, keep your battery charged.
13
• When the battery only has enough charge for about 30 minutes of talk
time, the headset triggers a low battery alert: you’ll hear a periodic beep.
• When the battery no longer has enough charge to operate the headset,
the headset will power o; you won’t be able to turn it back on until you
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.
14
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 specically 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:
15
• 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. When the headset has reached its maximum level,
you will hear a beep. Press VOL again and the headset will take the lowest
volume level.
• When you turn the headset o, it keeps the volume level at the last used
level.
• 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.
