solely upon any electronic device for essential communications (e.g.
medical emergencies). Remember, in order to make or receive calls,
the headset and the electronic device connected to the headset must
be switched on and in a service area with adequate mobile signal
strength. Emergency calls may not be possible on all mobile phone

+60

。C(+140。F) or under -20。C(-4。F). For maximum battery capacity,

use the battery at room temperature. If the battery is used in low
temperatures, the battery capacity will be reduced. The battery can
only be charged in temperatures between +10

。C(+50。F) and +45。C

(+113

。F). For your safety, do not remove the battery incorperated in

warrants this product to be free from defects in design, material and
workmanship at the time of its original purchase by a consumer, and

Limited warranty

Avoiding hearing damage Permanent hearing loss may occur if you

use your headset at a high volume. Set the volume to a safe level.
Over time you can become accustomed to a higher volume that may
sound normal but can be damaging to your hearing. If you experience
ringing in your ears or muffled speech, stop listening and have your
hearing checked. The louder the volume, the less time is required
before your hearing could be affected.
Hearing experts suggest that to protect your hearing:

•Limit the amount of time you use the headset at high volume.

•Avoid turning up the volume to block out noisy surroundings.

•Turn the volume down if you can't hear people speaking near you.

Using headsets safely Use of headsets to listen to music while
operating a vehicle is not recommended and is illegal in some areas.
Be careful and attentive whilst driving. Stop using this device if you
find it disruptive or distracting whilst operating any type of vehicle or
performing any other activity that requires your full attention.
