The Buttons
Mode Button [MODE]
The Mode button is used to change keyer mode. In the main mode, press Mode button to cycle
among Speed, Weight, Tone and Reader Speed menus. This button is also used to enter and exit
the setup mode, or used in combinations with other buttons and paddles to perform special
functions.
Message Buttons [MSG1] to [MSG4]
There are four messages buttons corresponding to the four messages. To play a message, press
and release the corresponding message button. To save a message, press and hold a message
button for two seconds until the keyer responds with “GO” (dah-dah-dit dah-dah-dah). You may
then key in a message using the paddle, keyboard or terminal. Press any message button to end
the message. Refer to “The Memory” section on page 35 for explanation of the MFJ-464’s
message memory.
Button Combinations
The Mode button can be pressed in combination with another button or paddle to perform special
functions. To do this, press and hold the Mode button, within two seconds press another button
or paddle, and then release both buttons and paddle.
Decrement [MODE] + [MSG1]
Press and hold the Mode button and within two seconds press the MSG1 button to decrement the
serial number by one, effectively canceling the automatic increment applied when last played
from a message. The decrement function accommodates re-sending the last serial number, as
might be needed when a repeat of a contest exchange is requested, or canceling the exchange
with a station that proved to be a “dupe”. The unit will echo a "D" (dah-di-dit) for every number
that is decrement. Decrement serial number 0001 rolls over to 9999, because the number 0000 is
not used.
Increment [MODE] + [MSG2]
Press and hold the Mode button and within two seconds press the MSG2 button to increment the
serial number by one. The unit will echo an "I" (di-dit) for every number that is increment.
Increment serial number 9999 rolls over to 0001, because the number 0000 is not used.
Repeat Reader Buffer [MODE] + [MSG3]
Press and hold the Mode button and within two seconds press the MSG3 button to repeat the
reader buffer.
