Ref: BBOPR950DXD; EA278847 Cobra Electronics Corporation OPERATIONAL DESCRIPTION: The PR950DXD transceiver operates on both the General Mobile Service (GMRS) and Family Radio Service (FRS) frequencies. The radio will provide 0.831 watt ERP(d) when transmitting on GMRS frequencies (462.5500- 462.7250 MHz) and 0.478 watt ERP(d) on FRS specific frequencies (467.5625-467.7125 MHz). The RF power output of the PR950DXD is controlled by the internal microprocessor. When operating on a GMRS channel, the RF PA operating conditions are set by the microprocessor to provide 0.831 watt ERP(d). To extend battery life, a user power output control option is available to reduce the output power to 0.478W ERP. This option is only available when operating on a GMRS channel. When operating on an FRS channel, the microprocessor sets the RF PA operating conditions to those necessary to produce 0.478W ERP. There is no user power output control option w hen operating on an FRS channel. The power output is fixed at 0.478W ERP whenever an FRS channel is selected. It is required that the user obtain an FCC license to operate on the GMRS frequencies. This is specified in the users manual along with information on where to obtain the necessary application forms.

Safety Information For FRS/GMRS UNIT Your wireless handheld portable transceiver contains a low power transmitter. When the PTT button is pushed it sends out radio frequency (RF) signals. The device is authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless devices. Important: To maintain compliance with the FCC s RF exposure guidelines hold the transmitter at least 2 inches (5 centimeters) from your face and speak in a normal voice, with the antenna pointed up and away. If you wear the handset on your body while using the headset accessory, use only the Cobra supplied belt clip for this product and ensure that the antenna is at least 1 inch (2.5 centimeters) from your body when transmitting. If the distance between the antenna and the body is LESS THAN 1.0”(2.5cm) DO NOT USE THIS DEVICE IN THE BODY WORN CONFIGURATION. Use only the supplied antenna. Unauthorized antennas, modifications, or attachments could damage the transmitter and may violate FCC regulations. Normal Position: Hold the transmitter approximately 2” from your face and speak in a normal voice, with the antenna pointed up and away.
