CMU-300 User Manual SPECIFIC ABSORPTION RATES (SAR) Maximum: SAR 1.030 W/kg CDMA835 Body SAR 1.160 W/kg PCS1900 Body, SAR 0.424 W/kg Wimax Body THIS MODEL MEETS THE GOVERNMANETS REQUIREMENTS FOR EXPOSURE TO RADIO WAVES. Your wireless usb modem is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radiofrequency (RF) energy set by the Federal Communications Commission of the U.S. Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. The exposure standard for wireless modem employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. *
Tests for SAR are conducted with the modem transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the modem while operating can be well below the maximum value. This is because the modem is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. Before a modem model is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the limit established by the government adopted requirement for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) as required by the FCC for each model. The highest SAR value for this model modem when tested for use at the when worn on the body, as described in this user guide, is 1.160 W/Kg. (Body-worn measurements differ among modem models, depending upon available accessories and FCC requirements). While there may be differences between the SAR levels of various modems and at various positions, they all meet the government requirement for safe exposure. The FCC has granted an Equipment Authorization for this model modem with all reported SAR levels evaluated as in compliance Confidential 14/15 This document is the sole and exclusive property of C-motech. Not to be distributed or divulged without prior written agreement. CMU-300 User Manual with the FCC RF exposure guidelines. SAR information on this model modem is on file with the FCC and can be found under the Display Grant section of http://www.fcc.gov/oet/fccid after searching on FCC ID: TARCMU-300. SAFETY INFORMATION FOR RF EXPOSURE Body worn operation SAR compliance has been established in the laptop computer(s) with Horizontal slot configurations, and can be used in laptop computers with substantially similar physical dimensions, construction, and electrical and RF characteristics. Safety Information SAFETY INFORMATION FOR FIXED WIRELESS TERMINALS POTENTIALLY EXPLOSIVE ATMOSPHERES Turn your wireless modem OFF when in any area with a potentially explosive atmosphere and obey all signs and instructions. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. INTERFERENCE TO MEDICAL DIVICES Certain electronic equipment may be shielded against RF signal from you wireless modem. Turn your wireless modem OFF in health c are facilities when any regulations posted in these areas instruct you to do so. RF signals may affect improperly installed or inadequately shielded electronic system in motor vehicles. EXPOSURE TO RF ENERGY Use only the supplied or an approved replacement antenna. Do not touch the antenna unnecessarily when the wireless modem is in use. Do not move the antenna close to, or couching any exposed part of the body when making a conect. FCC Compliance Information This device complies with Part 15 of 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. Confidential 15/15 This document is the sole and exclusive property of C-motech. Not to be distributed or divulged without prior written agreement.
