Radiation Exposure Statement

RF exposure warning :The equipment complies with FCC RF exposure limits set forth for a

uncontrolled environment. The equipment must not be co-located or operating in conjunction
with any other antenna or transmitter.

Regulatory Information/ Disclaimers

Installation and use of this computer must be in strict accordance with the instructions
included in the user documentation provided with the product. Any changes or
modifications (including the antennas) made to this device that are not expressly approved
by the manufacturer may void the user’s authority to operate the equipment.

The manufacturer is not responsible for any radio or television interference caused by
unauthorized modification of this device, or the substitution of the connecting cables and
equipment other than manufacturer specified. It is the responsibility of the user to correct
any interference caused by such unauthorized modification, substitution or attachment.
Manufacturer and its authorized resellers or distributors will assume no liability for any
damage or violation of government regulations arising from failing to comply with these
guidelines.

FCC RF Exposure Statement --

Your device contains a radio transmitter and receiver. The radiated output power is far below the

international radio frequency exposure limits. These limits are part of comprehensive guidelines and

establish permitted levels of RF energy for the general population. The guidelines are based on the

safety standards previously set by international standards bodies: l American National Standards

Institute (ANSI) IEEE. C95.1-1992. l National Council on Radiation Protection and Measurement

(NCRP). Report 86. 1986. l Int’l Commission on Non-Ionizing Radiation Protection (ICNIRP) 1996.

l Ministry of Health (Canada), Safety Code 6. The standards include a substantial safety margin

designed to assure the safety of all persons, regardless of age and health.

SAR: 1.38w/kg Use of unauthorized or modified antennas may impair call quality and damage the

phone, causing loss of performance. To assure optimal phone performance and ensure human

exposure to RF energy is within the guidelines set forth in the relevant standards; always use your

device only in its normal-use position. Avoiding contact with the antenna area when the device is

IN USE optimizes the antenna performance.

FCC (Federal Communications Commission) Statement

This equipment has been tested and found to comply with the limits for a Class-B digital
device pursuant part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation.

This equipment generates, uses, and radiates radio frequency energy. If not being installed
and used in accordance with the instructions, it may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:

 Re-orient or relocate the receiving antenna.
 Increase the separation between the equipment and receiv

er.

 Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

 Consult the dealer or an experienced radio/TV technician for help.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:

 This device may not cause harmful interference.
 This device must accept any interference received, inclu

ding interference that may

cause undesired operation.

FCC Caution

To assure continued compliance, any changes or modifications not expressly approved by

the party responsible for compliance could void the user's authority to operate this

equipment. (Example: use only shielded interface cables when connecting to computer or

peripheral devices).

Power Conservation

This handheld computer consumes less power compared to conventional consumer
computers. The power consumption may be further reduced by properly configuring the
Power Management Setup.

It is recommended that the power saving features be enabled even when not running on
battery power. Power Management features can conserve power without degrading system
performance.

Power Safety

There are specific power requirements for your handheld computer:

 Only use an approved AC adapter designed for this handheld computer.
 There is a 3-prong grounded plug for the AC adapter. The 3rd prong is an important

mechanism for ensuring product safety. Please do not neglect the importance of this
mechanism. If you are unable to access a compatible outlet, please hire a qualified
electrician to install a compatible outlet for you.

 When unplugging the AC power cord, please make sure to

disconnect the cord by

pulling from the plug head instead of pulling from the wire to prevent wire damage.

 Make sure the power outlet and any other extension cord(s) you use can support the

total current load of all the connected devices.

 Before cleaning the handheld computer, please make sure it is disconnected from any

external power source.

Warning

Before any upgrade procedures, make sure the power is turned off, and all the cables

are disconnected. Also, it is advisable to remove your battery to prevent your handheld

computer from accidentally turning on.

Battery Precautions

 Only use batteries designed for this handheld computer. Using incompatible battery

types may cause explosion, leakage or damage to the computer.

 Do not remove the battery from the computer while the computer is powered on.
 Do not continuously use a battery that has been dropped, or that appears damaged

(e.g. bent or twisted) in any way. Even if the computer is able to continuously work with
a damaged battery, the circuit damage may occur and possibly cause fire.

 Always use the charger designed for this computer to r

echarge the battery. Incorrect

recharging may cause the battery to explode.

 Do not try to repair a battery by yourself. For battery service or replacement, please

contact with your service representatives.

 Please dispose damaged battery promptly and carefully. Explosion or leakage may

occur, if the battery is improperly handled or discarded.
