KC## ## = 00-15 sets a keying compensation value. Some radios have a key delay of 5 mS or
more. By entering KC05, the keyer will add 5 mS to the dots and dashes. This eliminates
the problems with a keying delay.

signs, numbers and letters. To study certain characters toggle R6 to set fixed character
sets. The default is set 01 [A - F]. Toggling R1 will send random word length. In word rec-
ognition mode, R8, the MFJ-493 sends common words heard on the air.
