INSTALLATION OF MOBILE TWO-WAY RADIO SYSTEM
If a rkobile two-way radio system is installed improperly or if a high-powered type is used, the EGI system
and other systems may be affected.
When the vehicle is to be equipped with a mobile two-way radio, observe the following precautions:
1. Install the antenna at the farthest point from control units.
2. lnstatt the antenna feeder as far as possible from the control unit harnesses (at least 30 cm [ If .8 in 1).
3. Ensure that the antenna and feeder are properly adjusted.
4. Do not instali a high-powered mobile two-way radio svstem.
