/SU#
/S+#
Speed Up – increases the overall speed by # WPM, where # is a single digit in the
range of 0 to 9.
/SD#
/S–#
Speed Down – decreases the overall speed by # WPM, where # is a single digit in the
range of 0 to 9.
/T##
Tone – sets the current sidetone frequency to approximately ##0 Hz, where ##
represents two digits in the range of 30 to 99. Note that this command sets the
sidetone to one of the 24 available frequencies.

/TU#

Tone Up – increases the sidetone frequency by # available frequency, where # is a
single digit in the range of 0 to 9.
/TD#
/T–#
Tone Down – decreases the sidetone frequency by # available frequency, where # is a
single digit in the range of 0 to 9.
/U##
Ultra Speed – sets the ultra speed mode for a message at speed of ##0 WPM, where
## represents two digits in the range of 10 to 99. For example, “10” is 100 WPM and
“99” is 990 WPM. This command is used primarily for meteor scatter work. Note
that Farnsworth, Weighting, Character Space, Word Space, Keying Compensation,
and Tone settings are disabled during ultra speed message transmission. Also,
messages using both regular speed and ultra speed can be created. To exit the ultra
speed mode, set ## to 00 such as /U00 and the message will return to regular speed.
Alternately, the message can be returned to a lower regular speed by use of the /S, /F,
or /W command.
/W##
Weight – sets the code weight to ## percent, where ## represents two digits in the
range of 25 to 75.
/WU#
/W+#
Weight Up – increases the code weight by # percent, where # is a single digit in the
range of 0 to 9.
/WD#
/W–#
Weight Down – decreases the code weight by # percent, where # is a single digit in
the range of 0 to 9.
/X##
Xmit – keys the keyer for ## seconds, where ## represents two digits in the range of
01 to 99. When setting time under 10 seconds, leading zero must be used. Time
greater than 99 seconds is obtained by using consecutive commands that total the
desired value. Set ## to 00 to key continuously for tuning the transmitter. For
example: KEY 1 SEC /X01 KEY 1 MIN /X60 KEY 1 MIN 39 SEC /X99 KEY 2
MIN /X60 /X60 KEY INFINITE /X00.
