The
FT-818
may be connected to an external 13.8 Volt DC power source providing at
least 3 Amps of continuous-duty current.. The supplied
E-DC-6
DC cable may be used
for DC connections.
While connected to an external DC source, if you have installed the supplied
SBR-32MH
Ni-MH Battery Pack, the
E-DC-6
connection to the external DC power source will allow
operation of the
FT-818
while charging of the
SBR-32MH
is in progress.
When making DC power connections, be absolutely certain to follow the markings on the
E-DC-6
so as to ensure proper polarity of the connection to the power supply. Connect

Notice
Be extremely careful when making power supply connections. Use only a 13.8
Volt DC Supply, and carefully observe the proper electrical polarity. Serious dam-
age may result if these precautions are not observed.
The Limited Warranty on this product does not cover damage caused by improper
power supply connections, or improper power supply voltage.
Important Note
Occasionally, the 430 MHz transmit signal may behave abnormally when the FT-
818 is operated using an External Power Supply and the whip antenna, especially
with the antenna in close proximity to surrounding metal objects.
If abnormal transmitter operation is ex-
perienced, wind one turn of the E-DC-
6 DC cable around the supplied ferrite
core, and snap its two halves together,
per the illustration below. Install the
core as close as possible to the DC
plug, as shown.
