Bluetooth Information

Bluetooth is a short-distance
two-way wireless communication technology
capable of transmitting data, commands, and audio
between devices. The Metro can connect with many devices such
as mobile phones, tablets, PDAs, computers, media players, and
more. Before you can use your Metro with your device they will
need to be paired.

02

Turn down the volume prior to using the headphones; adjust the
volume to the desired level once they are connected. Do not use
headphones at high volumes for extended periods of time as doing so
will result in permanent hearing damage. It is advised you keep
volume levels moderate to low at all times for your safety, even when
loud background noise is present.

Please visit www.osha.gov for more info.

Follow all laws governing use of headsets while driving, cycling,
walking, and/or running. Do not insert both earphones while driving a
car, cycling, operating machinery, or performing other activities that
require hearing surrounding sounds.

Care and Safety

Do not use your wireless headset around flammable gases

•

as fire or explosion may occur.

Keep the device and packaging out of the reach of children.

•

There are no user replaceable/reparable parts in the

•

headset. Disassembling it will void your warranty.

Do not expose the headset to moisture, sweat, water, or

•

other liquids, or excessive heat such as fire.

Do not drop as the internal circuit could be damaged.

•

Cleaning the Metro

Over time, the Metro may need to be cleaned. Most debris
can be cleaned off the Metro with a soft, dry cloth. For stuck
on debris, wipe with a cloth dampened with soapy water and
then again with a cloth dampened with water. Using chemical
cleaners on the Metro may cause discoloration and hardening
of the cable.

Storage

When not in use or charging, please store the Metro in the
included carrying case. Storing the Metro in a pocket or bag
without using the case may decrease the lifespan of the
Metro.

Changing and Cleaning Ear Tips

The Metro is an in-ear headphone that requires the ear tips to
seal with your ear canal. Three sizes of specially-made ear tips
are included to help you achieve the best fit and comfort. A
proper seal between the ear tip and ear canal is important for
getting the best sound.

Please try the ear tips you think will fit best to make sure you are
getting the best seal and comfort.

Removing Ear Tips

a)

Hold the ear tip firmly in one hand and the earpiece in the
other

With a firm grip on the ear tip, pull away from the earpiece at

b)

a 45 degree angle until you see the large part of the nozzle

Pull straight off the ear tip

Cleaning Ear Tips (Cont.)

Cleaning Ear Tips

a)

Remove the ear tips from your earphone as instructed
on page 9

b)

Take a cotton swab that is either dry or has been dampened
by a small amount of rubbing alcohol or hydrogen peroxide
on it (soapy water is OK)

c)

Swab around the nozzle of the earphone

d)

Swab the ear tip including the inside of the stalk
Note: Ear tips can also be submerged fully in rubbing alcohol or
hydrogen peroxide

e)

Wait for the earphones and ear tips to dry completely

f)

Put the tips back on the earphone, making sure they are fitted
securely

Caution:

Always make sure ear tips are installed properly on the earphone
nozzle to avoid an ear tip coming off in your ear. Frequent
cleaning of the outer portion of the nozzle and inside the stalk of
the ear tips will help keep them in place.

Using the Ear Fins

The Metro comes with two sets of ear fins
to help keep the Metro in place.

Installing the Ear Fins on the Metro

Choose the size that will best fit your ears

b)

The ear fin rings are tapered; side with the
larger opening should be oriented toward
the earphone housing

c)

Slide the ear fin on the earphone housing
and position it 3-4 mm (about 1/8”) from
the end of the earphone housing; it will be
necessary to stretch the ear fin a bit

d)

Adjust the fin positioning to lock the
Metro in place

Connecting to Paired Devices

Connecting:

When the Metro is turned on and not in pairing mode, it will
connect to last connected device automatically. If the last connected
device is not within range or does not have Bluetooth on, the Metro
will connect to other paired devices in the order of last connection.

If the Metro does not connect and remains in standby mode, a short
press of the Multifunction button will connect to the last connected
device with Bluetooth on and within range.

Notes

On some Bluetooth devices, such as some Nokia and Blackberry

•

cell phones, the settings must allow for automatic connection.
Please refer to your devices manual for further information.

On some Mac

•

enable Bluetooth audio every time you connect.

** The Metro is equipped with Multipoint, which allows
simultaneous connection to two devices. Multipoint is turned
off by default and will need to be turned on prior to use. **

Multipoint Use

Multipoint allows users to connect two devices simultaneously.
For example, it is possible to listen to streaming audio from one
device such as a computer, tablet, or dedicated media player while
still being connected to your phone with the ability to take incoming
calls without having to remove your Metro. During an incoming call,
the Metro will pause the audio stream and resume it after the phone
call is over.

Bluetooth devices are subject to interference
from other Bluetooth devices, microwave ovens,
power stations and transmission lines, Direct

operating on the 2.4 band. Eliminate as many
potential sources of interference as possible
while using your Bluetooth headphones.

Adjust the volume on your headset and device
as both control the sound

The Metro is at the maximum volume; try
increasing the volume on your connected device.

If using a wall charger, make sure it is plugged
in to a powered outlet. If using a computer,
make sure the computer is on and the USB port
has powered. If you are using a car USB port,
make sure the car is on.

Make sure that the pins of the charger are
engaged with the contact pads on the Metro.

Resolution

Make sure your Metro is powered on, Bluetooth is
enabled on your device, and it is within range.
Make sure your device is not connected to any
other Bluetooth headset. Make sure the Metro is
not connected to another device (two devices with
Multipoint enabled). If connecting still fails, power
off your Metro and turn it back on. If problems
persist, delete the device “AF71” from your list of
paired devices and pair the Metro again.

The Metro headset is compatible with many
Bluetooth versions, however not all versions of
Bluetooth support these functions and
functionality is dependent upon the operating
system of the device. Some functions, such as
“Rejecting a call,” “Redialing,” or “Voice dialing”
are only available if supported by your mobile
phone. Please check the device manual for
further information.
