Warning
Danger of fire! The radio’s protection mechanisms
rely 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:
■
>25W radios: 20A fuses (Tait IPN 265-00010-81)
■
25W radios: 10A fuses (Tait IPN 265-00010-80)
4.
Cut the negative (black) and the positive (red) wires where the in-line
fuse holders will be placed (as close to the power source as possible).
Notice
Do not install the fuses until the installation is ready to be
checked. For more information, refer to
“Checking the Installation” on
.
5.
Insert each end of the negative wire into each of the fuse crimp-
terminals and crimp them to force the metal contacts onto the wires.
6.
Push the two crimp-terminals into the clear plastic fuse cover. Close
the cover while the next steps are completed.
7.
Repeat steps 5 and 6 for the positive wire.
8.
Connect the negative wire to the battery ground terminal.
9.
Connect the positive wire to the battery positive terminal.
10.
Repeat steps 2 to 9 for the other radio body.
Notice
Do not install the fuses until the installation is ready to be
checked. For more information, refer to
“Checking the Installation” on
.
Power During Radio
Operation
It is important that both radio bodies power on at the same time. If that does
not happen (for example, the Power On Mode is set to Power On in the
programming application and power is applied to each body in sequence)
you must turn the system off then on again via the on/off key. It is not
recommended that you remove or apply power to a single radio body while
operating the radio system.
If power to one radio body is disrupted, you must turn the system off then
on again via the on/off key. If there is no power supply to one radio body
after the radio system is switched on, the other body and control head will
continue to operate as a single radio unit.
Notice
The ignition signal may fail to turn the remaining radio body
on and off if there is no power to one radio body. In this situation, the
on/off key must be used to continue operating the radio.
