MAIN DATA
Power Supply for RF-transmitting Equipment
[General]
1. A dedicated supply cable should be used for the RF-transmitting equipment
installation which should be as short as possible to the battery positive and
negative connections. Do not connect directly to the battery pillars, but use the
battery terminals provided.
NOTE
• Connections shall not be made to any electronic control unit feeds under any
circumstances. For example, avoid using cigar lighter as power sources for a
RF-transmitting equipment.
2. It is also recommended that, unless a molded twin supply cable is used, the two
supply lines be twisted together along their length in order to reduce radiated
noise or induce noise.
NOTE
• The supply cable from the RF-transmitting equipment should approach
the battery in such a way that, when terminated, the two wires can not be
inadvertently reversed, e.g. one wire is shorter than the other.
3. If ignition switch control is desired, the handset or control unit positive lead may
be connected through an appropriate in-line fuse to an available accessory circuit
or ignition circuit not powered during cranking.
