Avoiding Hearing Damage
Permanent hearing loss may occur if the receiver,
earbuds, headphones, speakerphone, or earpieces are used at high volume.
Set the volume to a safe level. You can adapt over time to a higher volume of
sound 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 receiver, earbuds, headphones,
speakerphone, or earpieces 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.

You should not rely on wireless devices for essential
communications, such as medical emergencies. Use of JCB Toughphone to
call emergency services may not work in all locations or all operating
conditions. Emergency numbers and services vary by region, and sometimes
an emergency call cannot be placed due to network availability or
environmental interference. Some cellular networks may not accept an
emergency call from JCB Toughphone if it does not have a SIM, if the SIM is
PIN-locked, or if you have not activated your JCB Toughphone.
Driving and Riding Safely
Use of JCB Toughphone alone or with
headphones (even if used only in one ear) while driving a vehicle or riding a
bicycle is not recommended and is illegal in some areas. Check and obey the
laws and regulations on the use of mobile devices like JCB Toughphone in the
areas where you drive or ride. Be careful and attentive while driving or riding a
bicycle. If you decide to use JCB Toughphone while driving, keep in mind the
following guidelines:
Give full attention to driving or riding and to the road.
Using a
mobile device while driving or riding may be distracting. If you find it
disruptive or distracting while operating any type of vehicle, riding a

off the road and park before making or answering a call.
