Previous view 2 INSTALLATION AND CONNECTIONS Power Supply Connections Make sure the [POWER] switch is OFF before connecting the DC power cable. • W e recommend using Icom's optional power supply (PS-126: DC13.8 V/25 A). DDConnecting the PS-126 power supply Use the attached AC cable to connect to AC outlet. Rear panel PS-126 GND To [DC 13.8V] DDBattery connections RWARNING! • NEVER connect to a battery without supplying a DC fuse, otherwise a fire hazard occurs. • NEVER connect the transceiver directly to a 24 V battery. The transceiver may not receive well on some frequencies when installed in a hybrid vehicle, or any type of electric vehicle (fuel cell vehicle). This is because vehicle's electric components such as the inverter system generate a lot of electric noise. • DO NOT use a cigarette lighter socket as a power source when operating in a vehicle. The plug may cause voltage drops and ignition noise may be superimposed onto transmit or receive audio. • Use a rubber grommet when passing the DC power cable through a metal plate to prevent a short circuit. The transceiver needs followings: • DC 13.8 V (Capacity: 22 A and over) • A power supply with an over current protective line and with a less voltage fluctuation or ripple DDConnecting a non-Icom DC power supply Connect the black DC power cable to the (-) Negative terminal, and the red DC power cable to the (+) Positive terminal.

A power supply with an over current protective line
and with a less voltage fluctuation or ripple

WARNING!
(About DC power supply)
Make sure DC power cable polarity is correct.
Red: Positive + terminal
Black: Negative – terminal
NEVER
cut the DC power cable between the DC
plug and fuse holder.
DO NOT
use unattached or undesignated DC pow-
er cable.
DO NOT
forcibly pull or bend the DC power cable.
Install the devices far enough from the place where
people might put things or step on the DC power
cable.

WARNING!
NEVER

otherwise a fire hazard occurs.
NEVER

The transceiver may not receive well on some frequencies
when installed in a hybrid vehicle, or any type of electric
vehicle (fuel cell vehicle). This is because vehicle’s electric
components such as the inverter system generate a lot of
electric noise.
DO NOT
use a cigarette lighter socket as a power source
when operating in a vehicle. The plug may cause voltage
drops and ignition noise may be superimposed onto trans-
mit or receive audio.

through a metal plate to prevent a short circuit.
