Motorola nextel ic402 用户手册

If your mobile device has an external antenna, use only a 
Motorola-supplied or approved replacement antenna. Use of 
unauthorized antennas, modifications, or attachments could 
damage the mobile device and/or may result in your device not 
complying with local regulatory requirements in your country.
DO NOT hold the external antenna when the mobile device is IN 
USE. Holding the external antenna affects call quality and may 
cause the mobile device to operate at a higher power level than 
needed.

When placing or receiving a phone call, hold your mobile device 
just like you would a landline phone.
If you wear the mobile device on your body, always place the 
mobile device in a Motorola-supplied or approved clip, holder, 
holster, case, or body harness. If you do not use a body-worn 
accessory supplied or approved by Motorola, keep the mobile 
device and its antenna at least 2.5 centimeters (1 inch) from your 
body when transmitting.
When using any data feature of the mobile device, with or 
without an accessory cable, position the mobile device and its 
antenna at least 2.5 centimeters (1 inch) from your body.
Using accessories not supplied or approved by Motorola may 
cause your mobile device to exceed RF energy exposure 
guidelines. For a list of Motorola-supplied or approved 
accessories, visit our Web site at www.motorola.com.

Nearly every electronic device is subject to RF energy interference 
from external sources if inadequately shielded, designed, or 
otherwise configured for RF energy compatibility. In some 
circumstances your mobile device may cause interference with 
other devices.
This device complies with Part 15 of the FCC Rules. Operation is 
subject to the following two conditions: (1) this device may not 
cause harmful interference, and (2) this device must accept any 
interference received, including interference that may cause 
undesired operation.
