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.
