NOTICES TO THE USER Government law prohibits the operation of unlicensed radio transmitters within the territories under government control. Illegal operation is punishable by fine and/or imprisonment. Refer service to qualified technicians only. FCC WARNING This equipment generates or uses radio frequency energy. Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly approved in the instruction manual. The user could lose the authority to operate this equipment if an unauthorized change or modification is made. INFORMATION TO THE DIGITAL DEVICE USER REQUIRED BY THE FCC This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can generate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that the interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. Consult the dealer for technical assistance.

REPEATER OPERATION Note: Please consult your dealer for programming the repeater. Due to the frequency stability on the 6.25 kHz bandwidth channel, when operating the repeater using an optional OCXO unit, allow the unit to warm up for 24 hours after turning the power on. After turning on the power, wait for approximately 10 seconds for the VCXO or 5 minutes for the OCXO (when mounting) to warm up. During this time, the CH/STATUS Display will blink. The keys will function when they are pressed. When power is applied to the unit, the POWER indicator lights green. Turn the VOLUME control clockwise until a click sounds, to unmute the audio. Rotate to adjust the audio. Turn the VOLUME control counterclockwise fully to mute the audio. The BUSY indicator lights green while receiving a signal and the TX indicator lights red while transmitting. u REF IN jack Connect from another repeater within the site to receive a reference signal. i FUSE Insert 7.5 A blade fuse into this fuse holder. o DC 13.8V jack Connect a 13.8 V DC power supply to this jack.
!0 TX OUT jack Connect a TX antenna or a duplexer to this BNC receptacle. TRANSCEIVER OPERATION Receive Adjust the volume to your desired level. You may need to readjust the volume if you are having interference while receiving a message from your dispatcher or another member in your fleet. The BUSY indicator lights green while a signal is being received. Transmit 1 Listen to the channel before transmitting, to make sure it is not being used. 2 Press the microphone PTT switch, then speak in your normal speaking voice. The TX indicator lights red while transmitting. 3 When you finish speaking, release the PTT switch. C Terminal Description MIC (Modular Jack) Pin NO.

Antenna Gain: 0 dBd referenced to a dipole. The Federal Communications Commission has adopted a safety standard for human exposure to RF (Radio Frequency) energy which is below the OSHA
(Occupational Safety and Health Act) limits. Antenna Mounting: The antenna supplied by the manufacturer or radio dealer must not be mounted at a location such that during radio transmission, any person or persons can come closer than the above indicated minimum safe distance to the antenna, i.e. 30 cm (1 foot). To comply with current FCC RF Exposure limits, the antenna must be installed at or exceeding the minimum safe distance shown above, and in accordance with the requirements of the antenna manufacturer or supplier. Vehicle installation: The antenna can be mounted at the center of a vehicle metal roof or trunk lid, if the minimum safe distance is observed. Base Station Installation: The antenna should be fixed-mounted on an outdoor permanent structure. RF Exposure compliance must be addressed at the time of installation. Antenna substitution: Do not substitute any antenna for the one supplied or recommended by the manufacturer or radio dealer. You may be exposing person or persons to excess radio frequency radiation. You may contact your radio dealer or the manufacturer for further instructions. Maintain a separation distance from the antenna to person(s) of at least 30 cm (1 foot). You, as the qualified end-user of this radio device must control the exposure conditions of bystanders to ensure the minimum separation distance (above) is maintained between the antenna and nearby persons for satisfying RF Exposure compliance. The operation of this transmitter must satisfy the requirements of Occupational/Controlled Exposure Environment, for work-related use, transmit only when person(s) are at least the minimum distance from the properly installed, externally mounted antenna. Transmit only when people outside the vehicle are at least the recommended minimum lateral distance away from the antenna/
vehicle. B59-xxxx-00
