INTRODUCTION IMPORTANT SAFETY INSTRUCTIONS
Dear mobile phone users,
Congratulations on having purchased your ClarityLife mobile
phone! This booklet will provide you with the most essential
information needed for quick familiarization with your new
mobile phone. You can use the following pages of this user guide
to decide on just how much time you want to invest in getting to
know the most important functions of your mobile phone.
We hope you will enjoy using your ClarityLife phone.
Please read the following safety instructions before using your ClarityLife C900 Dual Band
Mobile Phone and accessories. Please keep these instructions for your reference. When
using this product, these safety precautions and warnings should be followed to reduce the
risk of fire, electric shock, injury to persons and damage to property. Additional warnings
may be present on the product, packaging, or in the user instructions.
WARNINGS
Emergency Call Feature
When the emergency button is pressed the emergency numbers saved in the phone’s
address book will be called in the order you have selected until a party is reached. Up
to five emergency numbers may be saved in the address book. The numbers and the
order they will be called must be entered into the phone in order to ensure the desired
numbers are dialed when the emergency button is pressed. After you have entered
your five emergency numbers, you should test the phone’s emergency call feature by
pressing the emergency button to ensure that you have correctly entered the numbers
into the phone.
Since the phone service must be purchased in advance through monthly pre-paid
credits, you must ensure that you have made your pre-payment in order for the phone
service to remain activated. If you do not make your monthly pre-payment or if you do
not make a full monthly payment, you will lose your phone service, and the phone and
the emergency call feature will not be available.
You must also ensure that the phone’s battery is fully-charged at all times and that the
phone is in good working condition in order for the emergency call feature to work.
If the phone is outside of a coverage area, if network service is temporarily suspended
by the network carrier, or if there is network or phone interference, the emergency call
feature may not be available during those times.
This phone is not equipped with a global positioning service or other means to locate
the physical location of the phone. Consequently, if an emergency situation arises but
you are unable to provide your location to an emergency contact person in your ad-
dress book, neither they nor an emergency response service may be able to locate you.
The SIM card must be installed and activated before you will receive any phone service.
If the SIM card is damaged or replaced, the emergency contact numbers you entered
into the phone will be lost. In that case you must re-enter your five emergency contact
numbers into the phone’s address book in order to restore the emergency call feature.

6 7
After you have re-entered your five emergency numbers, you should test the
phone’s emergency call feature by pressing the emergency button to ensure that you
have correctly entered the numbers into the phone.
RADIO FREQUENCY INTERFERENCE
Pacemakers
The Health Industry Manufacturers Association recommends that a minimum sepa-
ration of 6 inches be maintained between a handheld wireless phone and a pace-

MAINTENANCE AND CARE
Handling the Phone
Do not drop, disassemble, open, crush, bend, deform, puncture, shred, microwave,
incinerate, paint, or insert foreign objects into the phone.
If the phone has been submerged in water, punctured, or subjected to a severe fall,
do not use it until you take it to an authorized service provider. For service informa-
tion, contact Clarity at 1-800-426-3738.
Discontinue use of your phone and contact Clarity at 1-800-426-3738 if
the product overheats, has a damaged cord or plug or if the product has
been damaged.
Removable Battery
This phone contains removable battery cells. Change the battery cells only as
directed in the user manual.
Connecting Accessories
Do not force connectors into ports. In case of experiencing unreasonable resistance
when attempting to insert a connector in a port, check for compatibility, obstruc-
tion in the port, or a disfigured connector.
Do not insert anything into the phone other than as directed in the user manual
because this may cause damage to the internal components or cause injury to you.
Not Customer Serviceable
This phone is not customer serviceable. Do not attempt to repair or modify the
phone. Doing so may result in injury or void your warranty.
Product Cleaning
Use only a slightly damp lint-free cloth to clean the phone. Use of household clean-
ers, alcohol, or other chemicals may damage your mobile phone.
USE ENVIRONMENT
Avoiding Water and Wet Locations
Do not use the phone in rain, or near washbasins or other wet locations. Take care
not to spill any food or liquid on the phone. In case the phone gets wet, unplug all
cables, turn off the phone before cleaning, and allow it to dry thoroughly before
turning it on again. Do not attempt to dry the phone with an external heat source,
such as a microwave oven or hair dryer.
Choking Hazard
Never allow children to play with the phone or accessories—small parts may be a
choking hazard.
Explosive Atmosphere Warning
Do not use or charge the phone in areas with potentially explosive atmospheres
such as (but not limited to): fueling areas, blasting areas, in vehicles transporting
flammable fluids, etc. Obey all posted signs.
LISTENING LEVEL WARNING
Exposure to high volume sound levels may damage your hearing. Although there
is no single volume setting that is appropriate for everyone, you should always use
your headset or headphones with the volume set at moderate levels and avoid
prolonged exposure to high volume sound levels. The louder the volume, the less
time is required before your hearing could be affected. You may experience different
sound levels when using your headset or headphones with different devices. The
device you use and its settings affect the level of sound you hear. If you experience
hearing discomfort, you should stop listening to the device through your headset or
headphones. To protect your hearing, some hearing experts suggest that you:
1. Set the volume control in a low position before putting the headset or head
phones on your ears.
2. Limit the amount of time you use headsets or headphones at high volume.

C900 Parts Checklist
3. Avoid turning up the volume to block out noisy surroundings.
4. Turn the volume down if the sound from the headset or headphones prevents
you from hearing people speaking near you. See www.plantronics.com/
healthandsafety for more information on headsets and hearing.
Exposure to Electromagnetic Energy in the Radio Frequency Band
When turned on, this device transmits and receives electromagnetic radiation in
the radio frequency (RF) bandwidth through its antenna. By international scientific
agreement, the unit of measurement of RF energy is the “specific absorption rate”,
or SAR. In the United States, the applicable SAR limit for the C900, set by the FCC
is 1.60 mW/g (millionths of watts per gram of mass), or 1.60 W/Kg (watts per
kilogram of mass). The maximum SAR exposure measured for the C900 was 0.738
W/Kg when the phone was turned on but not in use (body position), and 0.264 W/
Kg when the phone was in use (cheek position). In all cases, the phone was passed
by an independent testing facility.
Disposal and Recycling
Check and follow local laws regarding disposal and recycling of your phone.
