12 Additional information
Variations in SAR below the radio frequency exposure guidelines do not mean that there are variations
in safety. While there may be differences in SAR levels among mobile phones, all Sony Ericsson
Mobile Broadband Modems are designed to meet radio frequency exposure guidelines.
More information on radio frequency exposure and SAR can be found on:

Personal medical devices
Mobile Broadband Modems may affect the operation of cardiac pacemakers and other implanted
equipment. If a minimum distance of 15 cm (6 inches) is kept between the MD300 and the
pacemaker, the risk of interference is limited. If you have any reason to suspect that interference is
taking place, immediately turn off your MD300. Contact your cardiologist for more information.
For other medical devices, please consult your physician and the manufacturer of the device.
Children
DO NOT ALLOW CHILDREN TO PLAY WITH YOUR MD300. THEY COULD HURT
THEMSELVES OR OTHERS, OR COULD ACCIDENTALLY DAMAGE THE MOBILE
BROADBAND MODEM. YOUR MOBILE BROADBAND MODEM MAY CONTAIN SMALL
PARTS THAT COULD BE DETACHED AND CREATE A CHOKING HAZARD.
