External speakers are optional if a graphical control head with a speaker
is used. External speakers with some spatial seperation are useful in a
dual-radio configuration to help confirm which torso is receiving.
An ignition sense cable is optional.
Warning

on the correct fuses on both the negative and positive power supply
leads being present. Failure to fit the correct fuses may result in fire
or damage to the radio.
The correct fuse types are:
■
>25 W radios: 20 A fuses (Tait IPN 265-00010-81)
■
25 W radios: 10 A fuses (Tait IPN 265-00010-80).

Installation Considerations
Inspect the vehicle and determine the safest and most convenient position
for mounting the radio bodies and control head, and routing the various
cables.
Notice
The radio bodies must be less than 0.5 m (1.6 ft.) apart.
Caution
If using accessories that do not provide IP54 protection (for
example, control-head interface box, or hand-held control head remote
interface box), a mounting position away from water, dust, and other
environmental hazards should be selected.
