Electronic Life Supporting Devices and Medical Devices DANGER: The operation of any radio transmitting equipment, such as the CDM-820, may cause interference with medical devices. The signal you transmit can interfere with the operation of medical equipment used for treatment, communication, monitoring or analysis. Before using the CDM-820 in conjunction with life supporting devices such as cardiac pacemakers, defibrillators, insulin diffu-
sion pumps and related instruments, contact your physician. DO NOT use the CDM-820 in locations bearing warning signs that caution against radio transmission, and always request permis-
sion before using the unit near medical equipment. Electronic Devices Most modern electronic equipment is shielded from RF signals. However, certain electronic equipment may not be shielded against RF signals from your CDM-820. Some digital wireless phones may interfere with some types of hearing aids. In the event such interference occurs, you should consult your service provider. Emergency Calls The operation of your CDM-820 is dependent on radio signals, cellular and landline telecommunication networks. Therefore, the CDM-820 cannot guarantee a connection under all conditions - it is important that you never rely exclusively on any cellular product for emergency communications. S a f e t y Electrical Shock The CDM-820 uses internal voltages/currents that could pose possible electric shock hazards, which could result in bodily injury. For your safety, DO NOT attempt to open the CDM-820 for any purpose. Precautions Unplug the CDM-820 from the electrical outlet should one or more of the following occur:
If the AC power supply, its cord or plug is damaged or frayed.
If liquid has been spilled into the CDM-820, or it has been exposed to water or rain.
If the CDM-820 has been subject to an extreme physical blow.
If the CDM-820 does not operate normally according to these instructions, and the Troubleshooting Guide within this User Guide has not solved the problem. CDM-820 User Guide 1 y t e f a S
If the unit exhibits a distinct change in performance that is not documented in these instructions. Under any of these conditions, DO NOT attempt to service the CDM-820 yourself, as this could result in risk of fire or personal injury. FCC RF Exposure Information WARNING! Read this information before using this device. Your CDM-820 is a low power radio transmitter and receiver. When it is ON, it receives and also sends out Radio Frequency (RF) signals. In August 1996 the Federal Communica-
tions 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 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. Your CDM-820 meets and/or exceeds the governments standard for maximum permissible exposure to RF exposure of less than 1mw / cm2. CDM-820 User Guide 2 This device was tested with the significant source of emissions (antenna) kept 1.8 cm. from the body. Please maintain this distance to comply with FCC RF exposure requirements. Always install the unit in a place that will ensure that no part of the body will be within 20 cm of the unit. Use an extension phone located in another room, or remotely install the unit in a closet or on the wall high enough to maintain 20 cm distance while the unit is in operation. The CDM-820 was tested and found to be in compliance with the MPE levels required by the FCC and Industry Canada. The MPE value for this model is .65 mW / cm2. This test was done with the transmitter operating at its maximum power output. In normal operations the RF output is lower due to the control signal sent from the base station site. Further information related to exposure to RF energy can be obtained at the FCCs website:www.fcc.gov/oet/rfsafety. The long term characteristics or the possible physiological effects of radio frequency electromagnetic fields have NOT been investigated by U.L. Radio Frequency Energy and Explosives DO NOT store or operate the CDM-820 in the same area where flammable liquids, gases, or explosive materials are stored. Frequencies from the CDM-820 can interfere with blasting opera-
tions. DO NOT operate the CDM-820 near areas where blasting operations are in progress or in areas posted Turn off two-way radio. Ventilation Requirement DO NOT place the unit on surfaces such as a bed, sofa, rug, or other similar surface, or place anything on the unit. DO NOT push any object through the slots and openings in the cabinet. The object may touch dangerous voltage points or cause damage to the CDM-820 which could result in risk of fire or electrical shock. Antenna Safety Use only the supplied or an approved replacement antenna
(AX-702). Unauthorized antennas, modifications or attachments could damage the unit and may violate FCC Regulations and/or IC Standards. DO NOT touch the antenna unnecessarily when the CDM-820 is in use. Contact with the antenna affects the call quality and may cause the unit to operate at a higher power level than otherwise needed.
