MFJ-422E/422EX Instruction Manual

Electronic Keyer Paddle

4

Connections

1.

A nine volt battery (not included) may be installed. Remove the case by
removing the screws on the bottom that secure it to the paddle. A battery
clip, located inside the case, is provided for installing a nine volt battery.

2.

A 12 Vdc power supply may also be used to power the MFJ-422E. A
2.1mm coaxial plug with a positive center and a negative sleeve should be
used to power this unit. The MFJ-1312D, an optional power adapter, is
available from MFJ Enterprises, Inc. The battery is automatically
disconnected when external power is used.

3. The keying circuit allows keying of grid-block and solid state transmitters.

Keying output connection is made with a quality standard shielded RCA
cable between your radio key input and the MFJ-422E's

Key Output

jack.

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 or not at all when the jumpers are
connected to the wrong positions.

Keyer Operation

1. A nine volt battery or an optional power adapter may be used to supply

power to the keyer.

2. The keyer should be turned on by pressing the

Power

button and the LED

is lit.

3.

The

Semi-Auto/Auto

button should be in the "out" position for automatic

operation.

4.

The user should now start sending with the paddle and adjust volume, tone,
weight, and speed to his or her preference.

5.

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
feature can be checked by setting the keyer to the lowest speed and tapping
first the dash lever and then the dot lever before the completion of the dash.
The keyer will provide both the dash and the dot. The dash memory can be
checked in a similar manner. The dot insertion feature allows the user to
insert a dot by tapping the dot lever while holding the dash lever in. The
dash insertion feature allows the user to insert a dash while holding the dot
