FCC RF EXPOSURE COMPLIANCE

In August 1996 the Federal Communications Commission (FCC) of the United States with its action
in Report and Order FCC 96-326 adopted an updated safety standard for human exposure to radio
frequency (RF) electromagnetic energy emitted by FCC regulated transmitters. Those guidelines
are consistent with the safety standard previously set by both U.S. and international standards
bodies. The design of this phone complies with the FCC guidelines and these international
standards.

Use only the supplied or an approved antenna. Unauthorized antennas, modifications, o

r

attachments could impair call quality, damage the phone, or result in violation of FCC regulations.

This MM-5100U CDMA card has been tested for FCC RF exposure hand and body SAR
compliance. In order to comply with FCC RF exposure requirements, this product must be
operated with the MM-5100U CDMA card. The use of this card in any other type of host
configuration may not comply with FCC RF exposure requirements and should be avoided.
During operation, a 1.5cm separation distance should be maintained between the antenna,
whether extended or retracted, and the user’s/bystander’s body (excluding hands, wrists,
feet, and ankles) to ensure FCC RF exposure compliance.

CAUTION

Change or modification without the express consent of CMOTech Co., Ltd. voids the user’s
authority to use the equipment. This equipment has been tested and found to comply with the
limits pursuant to Part 22 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in an appropriate installation. This equipment generates,
uses, and can radiate radio frequency energy and, if not used in accordance with instructions, can
cause harmful radiation to radio communication. However, there is no guarantee that interference
will not occur in a particular installation. If the equipment does cause harmful interference in radio
and television reception, which can be determined by turning the equipment on and off, the user is
encouraged to try to correct the interference by one or more of the following measures:

 Reorient or relocate the receiving antenna
 Increase the separation distance between the equip ment and the receiver
 Contact CMOTech Co., Ltd. Technical Support for assistance.
