Power Source Connec�on
Connect your power supply or ba�ery to the DC-IN connector. Current
capability of the DC power supply should be at least 8 amps. Ba�eries should
supply 10.5-16.5VDC and have capacity to supply up to 10 amps. Typical
current requirements on transmit are generally less than 8A. Use the provided
cable to connect the G90/S to your DC supply. The G90/S transmi�er is
designed in such a way that dropping supply voltage from a weak ba�ery has
li�le effect on the transmi�er output power.
The DC power supply must be connected in strict accordance with the
following figure to avoid a reverse polarity connec�on.
The red wire must be connected with the posi�ve pole of power supply and
black wire to the nega�ve pole of the power supply.
A Ferrite Choke may be a�ached to the power wires to prevent external RF
from entering the radio via its power lines and RF interference from inside
the radio from radia�ng externally via the power cable. When installing a
ferrite choke place it closest to the radio end of the DC cable.

Polarity of power cables should be checked carefully to avoid reverse
polarity when connec�ng your power supply or ba�ery.
Although the G90/S has reverse polarity protec�on reverse connec�on of
power should be avoided.
