01

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

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.

Do not use while driving a car, cycling, operating machinery, or
performing other activities that require hearing surrounding sounds or
are against local laws.

FCC Warning

Changes or modifications to this unit not expressly approved by
the party responsible for compliance could void the user’s authority
to operate the equipment.

NOTE: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

•

Increase the separation between the equipment and receiver.

•

Connect the equipment into an outlet on a circuit different

•

from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

•

This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:

(1)

this device may not cause harmful interference, and

(2)

this device must accept any interference received, including
interference that may cause undesired operation.

Safety and Care

When not in use, power the device off and store it in the

a)

included protective bag.

Clean with a soft, debris-free cloth. If necessary dampen the

b)

cloth with a diluted soap water solution. Never use chemical
cleaners on the headphone. Leather conditioner and cleaner
can be used on the ear pads.

This headphone was not designed for use while driving.

c)

Do not use your wireless headset around flammable gases

d)

as fire or explosion may occur.

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

e)

There are no user replaceable/reparable parts in the

f)

headset. Disassembling it will void your warranty.

If the device comes in contact with liquids, quickly wipe away.

g)

Using as Wired Headphone

The Venture comes with a 3.5mm audio jack on the back of the
left ear cup and an audio cable for wired use. This is convenient
for use where Bluetooth isn’t allowed such as on an airplane,
when the battery is depleted, if you want to listen to media from a
different device that isn’t paired, or just to save battery power.

Connect one side of the audio cable to the Venture and the other
side to the audio device.

Using wired audio and Bluetooth simultaneously: The Venture can
be used to listen to wired audio while still connected to another
device such as a phone.

When listening to wired audio and a phone call, media, or other
audio transmits from the connected Bluetooth device, the wired
audio will partially mute. Approximately 20 seconds after the
Bluetooth transmission ends, the wired audio will resume.

Resolution

Make sure you are within range of your Bluetooth-enabled
device

Bluetooth devices are susceptible to interference from other
Bluetooth devices, microwave ovens, power stations and
transmission lines, Direct Satellite Service (DSS), and wireless
devices operating on the 2.4 GHz 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

If using a wall charger, make sure it is plugged in to a powered
outlet. When charging from a computer, make sure the
computer is on and the USB port is powered. If you are using a
car USB port, make sure the car is on. The charging LED is not
visible from all angles; make sure you look at the LED area
from different angles.

Make sure the Venture is in pairing mode as indicated by red
and blue LEDs flashing in an alternating manner. Make sure
Bluetooth on your device is turned on and your device is within
range.

Make sure your Venture 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 headsets. Make sure
the Venture is not connected to another device. If connecting
still fails, power off your Venture and turn it back on.
If problems persist, delete the device “AF52” and pair the
Venture again.

The Venture 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 device. Please check the device
manual for further information.
