3. A squeeze or single lever key can be used. Squeeze key allows Iambic
operation. A 1/4-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 next be
connected to the tip of the plug and the dash wire to the ring. The VEC-202
becomes a manual keyer when a straight key is used. The unit will safely
key your transmitter and eliminate the shock hazard of high voltage being
present on the straight key.
Note: To use a straight key, first switch the keyer to the Semi-Auto mode
(button in). Again a 1/4-inch stereo phono plug should be used
because a mono plug will not work on a straight key in Semi-Auto
mode. Connect one wire to the ring of the plug and another wire to
ground. The tip of the plug should not used.
4. Output keying circuit allows keying of grid-block and solid state
transmitters. Remember this is internally jumper selected (refer to page 2).
The keying output connection is made with a RCA phono plug.
Note: Consult the transmitter's instruction manual to determine which
output to use. When in doubt, try both jumper positions. The
transmitter will key continuously when the jumpers are connected to
the wrong positions.
KEYER OPERATION
1. A 9-volt battery or an optional ac adapter may be used to supply power to
the keyer.
2. The key paddle should be connected to the Key jack on the rear panel of the
unit. A dual paddle squeeze key or a single lever key can be used.
3. Next, the keyer should be turned on with the Power switch.
4. The Semi-Auto switch should be in the "out" position for automatic
operation.
5. The user should now start sending with the paddle and adjust volume, tone,
weight, and speed to his or her preference.
6. The dot and dash memories make sending easier. The memories allow the
user to key a dot before the completion of a dash and vice versa. This
