If the dot-space ratio entered exceeds 1.5 or is less than 0.5, the ratio will be set to 1.0.
The dash-space ratio is set to 3.0 on turn-on and is adjustable from 2.0 to 4.0. To change the
dash ratio, enter [*][*][2] and the new dash ratio.
Example: A dash-space ratio of 3.7 is desired; press [*][*][2][3][#][7].
If the dash-space ratio entered exceeds 4.0 or is less than 2.0, the ratio will be set to 3.0.
The code speed is automatically adjusted for other than "perfect" dot and dash, ratios and is
based on the word "PARIS".
When a new dot-space or dash-space ratio is entered, the code speed will revert to the last
speed entered via "[*][*][8] or [*][*][9]". If no speed has been entered after turn-on, the keyer will
revert to 15 WPM after a dot or dash ratio change. If the variable speed change feature has
been used before changing the ratio, the speed will also revert to 15 WPM.
Dot and Dash Memories
5.
The selectable Dot and Dash Memories are enabled on turn-on. The Dot Memory allows inser-
tion of a dot during a string of dashes. For example, the letter "Q"could be sent as follows:
The Dash Memory operates in the same fashion, allowing the insertion of a dash in a string of
dots.
To disable the Dot Memory, press [*][3].
To enable the Dot Memory, press [*][*][3].
To disable the Dash Memory, press [*][4].
To enable the Dash Memory, press [*][*][4].
Full iambic operation is available with the dot and dash memories enabled or disabled. This
feature is useful for generating characters with alternating dots and dashes like the period and
the letter "C". To utilize this feature, hold both the dot and the dash paddles.

Transmitter Tuning

6.
To allow transmitter tuning, the keyer output transistors will be operated upon pressing [*][*][5].
The [5] key must be released quickly before the keypad tone is completed. Tuning will be
terminated by pressing any pad button or touching the dot or dash key paddle.
The tune feature does not operate in the memory LOAD mode.

Mistakes

7.
Incomplete, undesired entries may be terminated by pressing [#]. Unacceptable entries will be
ignored. For example, if a speed change were entered [*][*][8][2][#], the result will be no speed
change.
