3. If weight control adjustment is required, access the trimpot located next to
jumper JMP1 and adjust as desired.
4. A squeeze key with ¼-inch stereo phono plug and a two-conductor shielded
cable should be used. If separate shielded cables are used, the two shields
should be tied together and connected to ground. The dot wire should be
connected to the tip of the plug and the dash wire to the ring (reverse this
for left-handed operator).

5. Keying output circuit allows keying of grid-block and solid state
transmitters. Negative output keying is provided on a RCA phono jack.
Relay output keying is provided on a 3.5 mm stereo jack where the tip and
ring of the plug form output contact. Positive output keying is provided on
a 3.5 mm stereo jack where keying is available only from the tip of the plug;
as a result, a mono plug can also be used here.
Note: Consult the transmitter's instruction manual to determine which
output to use. When in doubt, use the relay contact output.
