inserting a word break (uses one unit of memory). If you make a mistake
entering a word, you can back up over it by briefly pressing and releasing the
same Message button. The keyer will erase the last word, then play the word
before it (if any) to let you know where you stopped. If deleting the first word of
the message, the keyer will play "GO" instead. At the end of your message,
press and hold the same Message button until the keyer sends an end of message
character "+" (di-dah-di-dah-dit) and the LED stops flashing. If you try to save
more characters than you have memory, the keyer will automatically end your
message and send you an end of message character. To play a message,
momentarily press the corresponding Message button. On-going message can be
stopped by tapping either paddle or pressing a Message button to send another
message. The speed cannot be changed during message sending and message
recording. Also, the output keying circuit is disabled during recording.
The messages are stored in non-volatile memory: message 1 has 120 units of
memory and the other three messages have 128 units of memory each. Each
normal character uses one unit of memory; only the rarely used 7-, 8- and 9-
element (dots and dashes) characters require two units of memory. Characters
with more than nine elements are ignored. When there are ten or less units of
memory in the message remaining, the LED will flash faster to let you know the
memory is running low.
Note: A straight key cannot be used to record the message.
Embedded Commands:
While in the message recording mode you may use embedded commands for
special features. To use an embedded command simply store the multi-character
embedded command code within your message.
