DC POWER CONNECTION
The TX3100 is designed for 13.8 volts DC, negative earth
installations only (i.e. where the negative terminal of the battery
is connected to the chassis or frame of the vehicle).
There are two recommended methods of installation.
Radio remains ON when the ignition switch is OFF
Connect the radio's negative (black) lead to the vehicle's chassis,
or if preferred, directly to the battery's negative terminal.
The radio's positive (red) lead should be connected via the 2
amp fuse to the battery's positive terminal. Alternatively, the
positive lead could be connected into the fuse box at a point that
has +13.8 volts continuously available (the battery side of the
ignition switch) via the 2 amp fuse.
Radio turns OFF with the ignition switch:
Connect the radio's negative (black) lead to the vehicle's chassis,
or if preferred, directly to the battery's negative terminal.
The radio's positive (red) lead should connect to an accessory
point in the vehicle's fuse box via the 2 amp fuse. This point
should supply +13.8 volts only when the ignition switch is turned
ON or in the ACCESSORY position.
