RD68 VHF
42
E03912 Issue 2.0
The quality of any connections and integrity of the cable (with-
out breaks in the sheathing) will directly affect the performance
of the radio. Poor soldering or corrosion of the terminals can im-
pair performance. We recommend that screw or crimp terminal-
type connectors are not used for any through-deck fittings – a
good quality waterproof solder terminal connector will be less
susceptible to poor connection due to corrosion of the contacts.
Note If the RD68 detects a problem with the antenna or antenna con-
nections, the display will show ANT when the PTT key is press-
ed. To avoid possible damage to the radio the antenna should
be checked immediately for any damage or poor connection.
4.3 Electrical interference suppression
Interference generated by the alternator of the engine may occa-
sionally cause problems. The RD68 has been designed to mini-
mize the effects of outside interference. However, precautions
should still be taken – route the power supply and antenna
cables away from the engine compartment. The cable run should
not be down the same trunking as other cables carrying high
current. The antenna cable should also be kept separate from the
radio’s power cable.
Engines with spark ignition—and also some refrigerators—
should be fitted with suppressors. Your local agent should be
able to give advice on this, and also supply suppression kits
where necessary.
