Dc Power Connection; High Voltage Warning - GME TX3350 Instruction Manual

Removing the microphone
1. Slide the rubber boot back along the microphone cord.
2. Squeeze the plastic tab on the microphone plug towards
the plug to unlock it while gently pulling the plug
outwards. If the plug does not come out easily, the tab
has not released correctly and should be squeezed again.

DC POWER CONNECTION

The TX3350 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.

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.

HIGH VOLTAGE WARNING

The TX3350 has a built-in, high voltage detection system to
warn you if an overvoltage situation occurs.
If the power supply voltage exceeds 18 volts DC, the channel
display will flash 'hi dc' for 5 seconds when the unit is first
turned ON, or at the time the voltage exceeds 18 volts. In
addition, when transmitting, the TX indicator will flash and
the transmitter will select low output power.
