MFJ-432 Voice Memory Keyer

Recording a message
Push the RECORD PLAY button. The REC LED should light. Press and hold the
appropriate message button while speaking into the microphone. Release the message
button when the message is complete. Pressing the PTT switch is unnecessary if using a
microphone connected in the EXTERNAL MIC jack. The radio will be keyed and the
message will be transmitted over the air if the PTT switch is pressed.
Re-recording the message replaces an existing message. A re-recorded message will
erase any messages that it overruns. See the section entitled
Message Memories
for more
detailed information.
A feature allowing immediate cancellation of an outgoing message can be installed. This
is accomplished by programming memory 4, and using it as a "cancel" button.
To use memory four as a cancel OGM (out going message) button:
1.) Place the Voice Keyer in the record mode.
2.)
Briefly
tap memory button four.
3.) Release the record button.
This action records a very short burst of no audio in position 4. If the operator is playing
any other memory, he or she can immediately silence the VK by tapping memory button
four.
Note:
Tapping four to cancel will not stop the automatic repeat function of message one.
Memory four
will
cancel the immediate memory one auto-repeat transmission, but
the auto-repeat button must be released to prevent VK from trying to repeat
message after the normal cycle time elapses.
Playing a message
Push the RECORD/PLAY button until the PLAY LED is lit. Press the correct message
button to play a message. The XMIT button in the outward position allows the user to
listen to a message without transmitting it. Press and lock the REPEAT MSG 1 button to
repeat message 1. The MFJ-432 will play message 1 once and then start transmitting it
over the air until the REPEAT MSG 1 button is released to the "out" position. To change
the delay time, a trimpot, labeled REPEAT DELAY, is accessible through a hole in the
back panel. A small slotted screwdriver can be used to adjust the trimpot.
