YOUR NEW DEX™ REMOTE
CONTROL
We hope you will be pleased with your Widex hear-
ing aid remote control. These user instructions ex-
plain how your remote control should be operated.
WARNING
This booklet contains important information and instructions.
Read this booklet carefully before you start using your re-
mote control.
INTENDED USE
This remote control is intended to operate the
CLEAR series hearing aids.
5
DESCRIPTION OF DEVICE
Your CLEAR hearing aid uses a proprietary wireless
technology, the WidexLink, to enable communica-
tion between the left and the right hearing aids, as
well as between the hearing aids and the RC-DEX
accessories.
The RC-DEX remote control gives simple access to
hearing aid functions such as volume adjustment
and program change. It is also provided with a light-
emitting diode (LED) for visual indication.

CARING FOR YOUR REMOTE
CONTROL
The remote control is a valuable object and should
be treated with care. Here are some things you can
do to prolong the life of your remote control:
WARNING
• Do not expose the remote control to extreme temperatures
or high humidity.
• Do not immerse it in water
CAUTION
• Clean the remote control with a soft cloth. Never wash your
remote control with water, cleaning solutions or other liq-
uids.
• Avoid dropping the remote control
14
CAUTION
• It is not recommended to keep your cell phone/PDA within
close proximity of the remote control e.g. same pocket.
• Never try to open or repair the remote control yourself. (To
be performed by authorized personnel only).
WARNING
Do not carry your remote control with you during X-rays,
MRIs and other scans or radiation treatments and never
place your remote control in a microwave oven. These are
some of the types of radiation that can damage your remote
control. Radiation from room surveillance equipment, burglar
alarms, mobile phones and similar sources is weaker and will
not damage your remote control. However, on occasion ra-
diation from devices such as certain burglar alarms, automat-
ic motion detectors and other electronics may cause notice-
able audible interference during remote control and hearing
aid use.
15
WARNINGS
WARNING
Batteries can be dangerous if swallowed or used improper-
ly. Never put a battery or hearing aid in your mouth for any
reason as you may risk swallowing it. Swallowing or improp-
er use can result in severe injury, or even fatalities. In case of
ingestion, contact your physician immediately and the 24
Hour National Button Battery Ingestion Hotline at at (202)
625-3333.
• Keep your remote control and its parts, accessories and
batteries out of reach of children and anyone else who
might swallow such items or otherwise cause injury to
themselves. Do not change batteries in front of them and
do not let them see where you keep your battery supply.
Discard used batteries carefully.
• Do not use your remote control on aircraft or in hospitals
without permission.
• Do not use your remote control in mines or other areas with
explosive gases.
16
WARNING
Risk of explosion if battery is replaced by an incorrect type or
recharged.
CAUTION
• Although your remote control has been designed to comply
with the most stringent international electromagnetic com-
patibility standards, the possibility cannot be excluded that
it may cause interference with other equipment, such as
medical devices.
