+When installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on installation location.
1)Keep the antenna as far as possible from the electronic
control units.
2)Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
3)Adjust the antenna and feeder line so that the standing-
wave ratio can be kept smaller.
4)Be sure to ground the radio to vehicle body.
