 Do not install this apparatus in a mechanically-unstable location, or where objects
may fall onto this product from above.
 To minimize the possibility of interference to home entertainment devices, take all
precautionary steps including separation of TV/FM antennas from Amateur
transmitting antennas to the greatest extent possible, and keep transmitting
coaxial cables separated from cables connected to home entertainment devices.
 Ensure that the DC power cable is not subject to undue stress or bending, which
could damage the cable or cause it to be accidentally unplugged from the rear
panel DC input jack.
 Be absolutely certain to install your transmitting antenna(s) such that they cannot
possibly come in contact with TV/FM radio or other antennas, or with outside
power or telephone lines.
Connection of Microphone and Headphone
Key, Keyer, and Computer-Driven Keying Interconnections
The FT-950 includes a host of features for the CW operator, the functions of which will
be detailed in the “Operation” section later. Besides the built-in Electronic Keyer, two
key jacks are provided, one each on the front and rear panels, for convenient
connection to keying devices.
The Menu system allows you to configure the front and rear panel KEY jacks according
to the device you wish to connect. For example, you may connect your keyer paddle to
the front panel KEY jack, and use Menu item “037 A1A F-TYPE” for paddle input,
while connecting the rear panel’s KEY jack to the keying line from your personal
computer (which emulates a “straight key” for connection purposes), and configure the
rear panel jack using Menu item “039 A1A R-TYPE.”
Both KEY jacks on the FT-950 utilize “Positive” keying voltage. Key-up voltage is
approximately +5V DC, and key-down current is approximately 1 mA. When
connecting a key or other device to the KEY jacks, use
only a 3-pin (“stereo”) 1/4” phone
plug; a 2-pin plug will place a short between the ring and (grounded) shaft of the plug,
resulting in a constant “key-down” condition in some circumstances.
VL-1000 Linear Amplifier Interconnections
Be sure that both the FT-950 and VL-100 are turned off, then follow the installation
recommendations contained in the illustration.
