FT-847 OPERATING MANUAL
(1) POWER Switch
This latching-type switch turns the transceiver on and
off. Push the switch in to turn the transceiver on, and
push it again to turn the power off.
(2) MOX Switch
This latching-type switch is used to switch the trans-
ceiver manually into the transmit mode (it thereby
duplicates the action of the microphone Push-To-Talk
[PTT] switch). Press it in to activate the transmit mode,
and press it again to release the transceiver back into
the receive mode.
CAUTION: Be sure to have an antenna or dummy load
connected to the appropriate antenna jack
when this switch is pushed. Failure to do so
may cause damage to the transceiver’s final
amplifier stage.

(3) TUNER Switch
This switch activates the optional (external) FC-20
Automatic Antenna Tuner of the optional ATAS-100
Active-Tuning Antenna System. A momentary touch
of this switch places the Antenna Tuner in line (recep-
tion is not affected). Pressing and holding this switch
in for ½ second activates the Automatic Matching
Mode, in which a carrier is generated and the tuner or
antenna’s microprocessor makes adjustments so as to
present a 50Ω impedance to the transmitter’s antenna
port.
CAUTION: Be certain to have an antenna or dummy load
connected to the appropriate antenna jack
before initiating Automatic Antenna Tuner
matching procedures.
(4) PHONE Jack
This ¼” 3-pin (“stereo”) jack is used for connection
to your headphones. When a plug is inserted into this
jack, the internal (or external) speaker will be cut off.
This jack’s impedance is optimized for use with 16Ω
to 32Ω headphone types.
