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:
■ 40W/50W radios: 20A fuses (Tait IPN 365-00010-81)
■ 25W radios: 10A fuses (Tait IPN 365-00010-80).

Organization for more information.
1.4 Choosing an Installation Configuration
The radio allows for different installation configurations for vehicles with
respect to ignition signal and standby current. For special configurations for
desktop and remote site installations, refer to the service manual.
The installation configurations described below are based on the following
hardware link configuration:
■ hardware link 1 (+13.8V battery power sense): fitted
■ hardware link 2 (ignition sense): fitted
For more information on the hardware links, refer to the service manual.
Direct Connection to
the Power Source
The radio’s power cable must always be connected directly to the power
source (battery).
Important Although it is possible to connect the radio in line with the
vehicle ignition, this is not recommended, as it may draw
too much current and damage the vehicle wiring and
steering column or ignition switch. This may also cause the
supply voltage of the radio to drop below the specified level.
The radio can always be turned on and off using the on/off button,
independent of the ignition signal.
Installation without
Ignition Signal
Connect the power cable directly to the power source as described in
“Connecting the Power Cable to the Power Source” on page 19.
