PROPER WEAR AND FIT

1. INSTALLING FINS, EAR TIPS AND CABLE CLIPS

a) Install stabilizer fins on the headset and rotate to find a suitable position

as shown:

b) Choose the eartips best suited for your ear size. Wear as follows:

c) Configure the cable management clips to reduce cable slack for a more

secure and comfortable fit.

PROPER WEAR AND FIT (Continued)

2. CHANGING EAR TIPS

The Metro2 is an in-ear headphone and requires the ear tips to seal
with your ear canal. An airtight seal between the ear tip and ear canal is
important for getting the best sound. Three sizes of ear tips are included to
help you achieve the best fit and comfort.

3. REMOVING EAR TIPS

Hold the ear tip firmly in one hand and the earpiece in the other and pull the
ear tip straight off the earphone nozzle.

4. INSTALLING EAR TIPS

a) Hold the earpiece in one hand and the ear tip in the other with its open

end facing the earpiece

b) Push the ear tip tube against the nozzle at a 45 degree angle

c) Push the ear tip completely onto the nozzle and wiggle the ear tip

until the bottom of the ear tip is flush against the base of the earphone
nozzle.

d) Gently pull on the ear tip to make sure it is installed securely. If it isn’t

installed securely, either push it onto the nozzle until it is or remove and
repeat steps a) through c)

PAIRING WITH BLUETOOTH DEVICES

Prior to using the headset for the first time, you have to pair it with a
Bluetooth-enabled audio device.

*** It is only necessary to pair your Metro2 once with each device ***

1. PAIRING

a) Open the Bluetooth menu (see sections 2 through 4 below) on the

device you wish to pair. Some devices require you to select “search for
devices” or “add new devices” in order to create a Bluetooth pairing.

b) Make sure the Metro2 is off and within 1 meter of your device.

c) Initiate pairing mode by pressing the multifunction button for 8

seconds until the red & blue indicator lights flash in an alternating
manner. (Note: The Metro2 will enter standby mode if not paired within
2 minutes.)

d) Select “Air-Fi Metro 2” when it appears on your device. If “Air-Fi Metro

2” doesn’t appear in the Bluetooth menu of your device, ensure the red
and blue indicator lights on the headset are flashing alternatively and
Bluetooth is enabled on your device.

If your device asks for a pin, enter “0000”.

e) The device will pair and then connect. After successful connection, the

blue indicator light on the Metro2 will flash twice every 4 seconds.

2. LOCATING THE BLUETOOTH MENU ON AN IPHONE, IPAD, OR IPOD
TOUCH

a) On your device, go to Settings

b) Select Bluetooth (Bluetooth is under the General menu in iOS 5.1.1

and older); if Bluetooth is not on, turn it on. The iPhone/iPad/iPod will
automatically search for new devices

7

PAIRING WITH BLUETOOTH DEVICES (Continued)

3. LOCATING THE BLUETOOTH MENU ON ANDROID ™ PHONES AND
TABLETS

a) On your device, go to Settings menu

b) Select Bluetooth (Bluetooth is under the Wireless & Networks menu in

older Android devices); if Bluetooth is not on, turn it on.

c) Select “Search for Devices” if your phone or tablet does not

automatically search for new devices

4. LOCATING THE BLUETOOTH MENU ON WINDOWS® PHONE 8 DEVICES

a) On your device, go to Settings

d) Select Bluetooth. If Bluetooth is not on, turn it on. The Windows Phone

will automatically search for new devices

If pairing fails after several tries, please refer to your device’s user manual
for further information.

For instructions on pairing other devices, please refer to your device’s user
manual.

CONNECTING WITH PAIRED DEVICES

When the Metro2 is turned on, it will automatically connect to previously
paired devices that have Bluetooth turned on and are within range, with
priority given to the most recently connected device.

The headset can remember 8 paired devices; when the number of paired
devices exceeds 8, the first paired device will be replaced.

If the Metro2 is in standby mode (turned on but no device connected), a
short press of the multifunction button will connect to the most recently
connected device that has Bluetooth turned on and is within range.

Notes:

• On some Bluetooth devices, such certain Nokia and Blackberry phones,
the settings must allow for automatic connection. Please refer to your
device’s manual for further information.

• On some Mac and PC computers you will need to manually enable Blue­tooth audio every time you connect

8

MULTIPOINT

Multipoint allows two Bluetooth devices to be connected to the Metro2
simultaneously.

1. TURNING ON MULTIPOINT: MULTIPOINT IS OFF BY DEFAULT. ENABLE
MULTIPOINT AS FOLLOWS:

a) Put the Metro2 in standby mode (turned on but with no devices

connected to it). Bluetooth may need to be turned off temporarily on
nearby devices so that they do not connect to the Metro2

b) Long press and + buttons in standby mode, and release them when

you hear four beeps of increasing tone.

2. SIMULTANEOUS CONNECTION OF TWO DEVICES

a) Pair two devices by following the pairing procedure for each device.

Both devices will need to be paired before multipoint can be used.

b) With multipoint enabled, when turned on the Metro2 will automatically

connect to the last 2 devices that have Bluetooth enabled and are
within range.

c) If a device that has already been paired does not connect automatically,

select “Air-Fi Metro 2” from the Bluetooth menu of the device.

d) To avoid connecting to multiple devices, disable Bluetooth on the

devices you do not want connected to the Metro2 or disable multipoint
(see page 10).

e) If you no longer want the Metro2 to connect to a device, remove the

“Air-Fi Metro 2” pairing from the Bluetooth menu of that device.

3. MULTIPOINT FUNCTIONALITY

Switching audio between two devices during media playback

a) Pause audio playback on the active device

b) Start audio playbck on the other connected device; it may take up to 10

seconds for the audio to switch.

Incoming calls will always take precedence over media. If media is playing
on one device and an incoming call is received on the other device, the
Metro2 will pause the media on the active device and activate the device
with the incoming call. Once the call is ended, the Metro2 will reactivate the
original device and resume playback (with most media applications).

4. TURNING MULTIPOINT OFF

We recommend keeping multipoint off if you don’t use this feature, which will
result in the best connectivity and battery life. Disable multipoint as follows:

Long press and — buttons in standby mode (see Section 1a on Page 9 for
standby mode instructions) and release them when you hear four beeps of
decreasing tone.

FACTORY RESET

Performing a factory reset will clear all of your paired devices and can be used
as a troubleshooting method. Use the following steps to perform a factory reset:

a)

Plug a charging cable into the Metro2

b)

Press and hold the Volume Up “+” button until you see both the blue
and red LEDs turn on. There will be four long tones. The red LED will
remain on until the Metro is disconnected from the charger.

Note: The first time the Metro2 is turned on after the factory reset, it will enter
pairing mode automatically. If the Metro2 was previously paired with a device,
the pairing must be deleted from the device and the pairing process will need
to be repeated.

WARNING

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.
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.

CLEANING INSTRUCTIONS

a) Remove the ear tips and the stabilizer fins from the earphones
b) Take a cotton swab that is either dry or has been dampened by a small

amount of rubbing alcohol or soapy water
c) Swab around the nozzle of the earphone
d) Swab the ear tip including the inside of the eartip
e) Swab the inside of the stabilizer fin ring

Note: Ear tips and stabilizer fins can also be submerged fully in rubbing

alcohol or hydrogen peroxide
f) Wait for the earphones and ear tips to dry completely
g) Put the ear tips and fins back on the earphone, making sure they are

fitted securely. Always make sure ear tips are installed properly on the

earphone nozzle to avoid an ear tip coming off in your ear.

Clean the cable and earphone housing as necessary using a cloth dampened
with soapy water, and then again with a damp cloth. Using chemical cleaners
on the Metro2 may cause discoloration and hardening of the cable and is not
recommended.
