Front Panel Controls & Switches 
1. [POWER] Switch 
Press and hold in this switch for two seconds to turn the transceiver on. Press and hold 
in this switch for two seconds, similarly, to turn the transceiver off. 
 
2. [ANT 1-2] Switch 
Pressing this selects either the ANT 1 or 2 jack on the rear panel, and allows 
convenient antenna switching at the press of button. The selected antenna jack is 
indicated at the Block Diagram Display in the display. 
 
3. [TUNE] Switch 
This is the on/off switch for the FT-950’s Automatic Antenna Tuner. 
Pressing this button momentarily places the antenna tuner in line between the 
transmitter final amplifier and the antenna jack (“TUNER” icon will appear in the 
display). Reception is not affected. 
Pressing and holding in this button for two seconds, while receiving in an amateur 
band, activates the transmitter for a few seconds while the automatic antenna tuner 
rematches the antenna system impedance for minimum SWR. The resulting setting is 
automatically stored in one of the antenna tuner’s 100 memories, for instant automatic 
recall later when the receiver is tuned near the same frequency. 
Pressing this button momentarily, while the Tuner is engaged, will take the Automatic 
Antenna tuner out of the transmit line. 
Note: When the Automatic Antenna Tuner is tuning itself, a signal is being transmitted. 
Therefore, be absolutely certain that an antenna  or  dummy  load  is  connected  to  the 
selected antenna jack before pressing and holding in the [TUNE] button to start 
antenna tuning. 
 
4. [MOX] Switch 
Pressing this button engages the PTT (Push to Talk) circuit, to activate the transmitter 
(the LED inside this button will glow red). It must be turned off (the red LED will be 
off) for reception. This button replicates the action of the Push to Talk (PTT) switch on 
the microphone. When engaging the [MOX] button, or otherwise causing a 
transmission to be started, be certain you have either an antenna or 50-Ohm dummy 
load connected to the selected Antenna jack.
