The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue.
Device types U7 Plus (FCC ID: 2ANMU-U7PLUS) has also been tested against
this SAR limit. The highest reported SAR values for head, body-worn accessory
are 0.75 W/kg, 0.79 W/kg respectively. The Max simultaneous SAR is 1.01 W/
kg. This device was tested for typical body-worn operations with the back of
the handset kept 10mm from the body. To maintain compliance with FCC RF
exposure requirements, use accessories that maintain a 10mm separation
distance between the user's body and the back of the handset. The use of belt

Rechargeable Battery Pack Safety
With very little care, you can optimize the battery life and maximize the lifespan
of the battery. Most importantly, use only the equipment in its ideal operating
temperature (as described in 1.5 Specifications on page 8) – do not leave it
in a hot trunk during the summer.
•Important Terms toUnderstand
“Battery life” means the time the equipment will run before it must be recharged
(sometimes this is also called “playtime” or “runtime”).
“Battery lifespan” means the total amount of time your battery will last before it
must be replaced.

- xi -
Preface
•Using the Equipment for the FirstTime
Be sure to fully charge (approx. 4 hours) the equipment when charging the
equipment for the rst time.
•Long-Term Storage & Maintenance
If you are putting away the battery for more than three months, it is recommended
that the battery should be stored separately and fully charged, and get recharged
every three months. If you store an uncharged battery, it could fall into a deep
worn-out state which would render it incapable of holding any charge. Be sure to
store the equipment and battery at the proper temperature (as described in 1.5
Specications).
•BatteryLifespan
The removable batteries for the equipment are designed to retain up to 80% of
their original capacity after 300 charging and recharging cycles when properly
maintained. You may choose to purchase new battery when it no longer holds
the su󰀩cient charge that meets your needs.
•The lithium-ion battery is currently one of the most popular battery packs.
The best advantage is that it has no memory e󰀨ect, so users needn’t worry
about that issue. Users can charge the battery anytime whether it is fully
drained or not. However, it’s recommended that users drain the batteryuntil
the system shows power shortage warning and then recharge the battery.

•Don’t expose the battery to elevated heat situations such as underdirect
sunlight in a car or nearre.
•Don’t disassemble the battery, or the battery leakage might cause skin
or eye injury. If electrolyte leaking from the battery contacts your skin or
clothing, immediately ush it with running water. If it splashes into eye,

charge. Be sure to store yourthe equipment and batteryatthepropertempera
ture(as described in 1.5 Specifications on page 8).
•Use the appropriate container to store the battery such as a paper box. Do
not allow a metal object to touch the terminal of the battery.
•The battery consists of precise electrical components and cells. Do not drop
or hit the battery.
General Cleaning Tips
You may need the following precautions before you begin to clean the device.
When you clean any single part or component for the device, please thoroughly
read and understand the details below.
1. We strongly recommended that you should shut down the system before
you start to clean any single components.
2. When you need to clean the device, please rub it with a piece of dry cloth.
3. Be cautious of the tiny removable components when you use a vacuum
cleaner to absorb the dirt on the oor.
4. Never drop the components inside the device or get circuit board damp or
wet.
5. Be cautious of all kinds of cleaning solvents or chemicals when you use it
for the sake of cleaning. Some individuals may be allergic to the ingredients.
6. Try not to put any food, drink or cigarette around the device.
Cleaning Tools
Although many companies have created products to help improve the process
of cleaning your devices and peripherals, users can also use household items to
clean their devices and peripherals. Below is a listing of items you may need or
want to use while cleaning your devices or peripherals. Keep in mind that some
components in your device may only be able to be cleaned using a product
designed for cleaning that component, if this is the case it will be mentioned in
the cleaning.
• Cloth: A piece of cloth is the best tool to use when rubbing up a component.
Although paper towels or tissues can be used on most hardware as well,
we still recommend you to rub it with a piece of cloth.

- 1 -
• Water or rubbing alcohol: You may moisten a piece of cloth a bit with
some water or rubbing alcohol and rub it on the device. Unknown solvents
may be harmful to the plastics parts.
• Vacuum cleaner: Absorb the dust, dirt, hair, cigarette particles, and other
particles out of the device can be one of the best cleaning methods. Over
time, these items can restrict the airow in a device and cause circuitry
to corrode.
• Cotton swabs: Cotton swaps moistened with rubbing alcohol or water are
excellent tools for wiping hard to reach areas in your keyboard, mouse,
and other locations.
• Foam swabs: Whenever possible, it is better to use lint-free swabs such
as foam swabs.
Recommended Cleaning Procedures
1. Close all application programs
2. Close operating software
3. Turn o󰀨 the equipment
4. Remove all peripherals
5. Disconnect the power cable
6. Proceed to clean.
Disposing of the Equipment
•Within the European Union
EU-wide legislation, as implemented in each Member State,
requires that waste electrical and electronic products carrying
the mark (left) must be disposed of separately from normal
household waste.
This includes monitors and electrical accessories, such as signal cables or
power cords. When you need to dispose of your display products, please
follow the guidance of your local authority, or ask the shop where you
purchased the product, or if applicable, follow any agreements made between
yourself. The mark on electrical and electronic products only applies to the
current European Union Member States.
