This product must be installed in accordance with national and local radio communications authorities and/or Health and Safety regulations.
DMR Mobile disconnect the vehicle battery without effecting devices, such as central locking mechanisms, engine management computers, security-coded in-car entertainment units and so on. Prolonged operation of the product when the vehicle engine is switched off could drain the vehicle battery. Avoid damage to fuel lines, hydraulic lines and existing cables. This product is suitable for 12V negative earth vehicles only. Do not use other supply systems, this may damage the product.
Vehicle Installation Guide Gas powered vehicles Check the vehicle to ensure that there are no gas leaks before starting an installation involving the use of electric tools that may ignite the fuel. DO NOT USE A NAKED FLAME. Butane and propane gases are heavier than air, and may be present in some lower parts of the vehicle and undetectable by smell. STOP if you notice any sign of a gas leak and inform the vehicle owner immediately.
DMR Mobile The transceiver must be installed away from cables carrying very high currents such as the starter motor cable or the electric traction motor and its cables on electric vehicles. Ensure that the cables are routed so that they are kept well clear of any existing vehicle system cabling. Secure all cabling to eliminate the possibility of damage by sharp edges or moving parts.
Vehicle Installation Guide Installing using the mounting bracket The mounting bracket must be screwed to an appropriate flat surface within the vehicle Use the bracket as the as a template to correctly position the holes before drilling a pilot hole. Secure the bracket into position using the six ST4.8x20 self-tapping screw. Place the transceiver into the middle of the mounting bracket. Adjust the transceiver position to a horizontal angle or 20 degrees angle (or angle of depression).
DMR Mobile DC supply connection With the transceiver end of the power connector resting in its intended final position, route the wires to the vehicle battery. If the power cable needs to be shortened, it must be shortened from the battery connection end. A fuse must be fitted to the positive line (red wire) when the cable has been shortened. A new fuse holder must be fitted (not supplied) because the existing fuse holder cannot be reused. The fuse must be positioned close to the battery terminal.
Vehicle Installation Guide Fist microphone The fist microphone should be located centrally for the operator(s) to access, using the hanger provided. The fist microphone connector has a direction indicator. With the direction indicator facing upwards, rotate the outer self-lock cover in a clockwise direction. Fit the connector to the transceiver ensuring that the self-lock cover fits over the corresponding connector on the transceiver.
DMR Mobile RF Compatibility Checks The following checks must always be carried out if the vehicle is equipped with electronic anti-skid, electronic ignition or engine management systems. The transceiver should be operated only for the time required to make an observation. An assistant will be required for the following checks. With the vehicle stationary and the engine running at fast idle, operate the transmitter.
