Note
If hardware link 1 is fitted (factory default) and the ignition signal
is not used, the standby current is approximately 50 mA. To reduce
the standby current to <3mA either:
■
remove hardware link 1, or
■
connect pin 4 (AUX GPI3) to pin 15 (AGND) of the
auxiliary con0nector.
Note
With the above two options, the radio always stays off when power is
first applied. The radio can only be turned on with the on/off button.
Installation with
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
.
Connect pin 4 (AUX GPI3) of the auxiliary connector to the ignition signal
as described in
“Connecting to the Auxiliary Connector (Ignition Signal,
Emergency Switch, External Alert Devices)” on page 21
.
The AUX GPI3 line must be programmed to ‘Power Sense (Ignition)’ and
active to ‘High’. For more information, refer to the online help of the
programming application.
Note
The TMAA04-05 ignition sense kit provides a suitable mating plug
for the radio’s auxiliary connector. The plug includes wiring for the
the ignition signal and analog ground.
