External DC Power Supply Connection
You may insert the cable plug of the optional SDD-
11/SDD-12 Cigarette Lighter DC/DC Converter into
the EXT DC jack located on the right side of the
transceiver. When making DC connections via the
SDD-11/SDD-12, be absolutely certain to observe
the proper voltage level and polarity guidelines.
The SDD-11/SDD-12 can be connected to 12
to 24 Volt DC power sources.
Do not connect any accessory unapproved
by YAESU to supply DC power; otherwise
the FTA-750/FTA-550 may be damaged.

exert a moderate "pinching" pressure on the base
as you press the antenna onto the radio's antenna
