Russian Set-up (970 only)
Russian stimulation therapy consists of a 2.5kHz medium frequency which
is modulated on and off in bursts that can be set anywhere between 1 and
100Hz. An overall surge envelope can also be applied with variable work
and rest periods.
The burst frequency can be set from 1 Hz to 100Hz by touching the ‘Burst’
button. 0-10 Hz is in 1 Hz steps, 10 – 50 Hz in 5 Hz steps, and 50 – 100 Hz
in 10 Hz steps.
The medium frequency bursts used for Russian stimulation are surged to
produce work and rest periods. The surge time (work) is fixed at 10
seconds. The ratio sets the off or rest time in ratio to the work period. For
example, if the ratio is set to 1:4 then the work period is 10 seconds and
the rest period is 40 seconds. Touch the ‘Ratio’ button to set the ratio to
any integer value between 1:1 and 1:5.
The surge status is displayed in the lower middle window button of the
display in the ‘Setup’ screen and to the right of its channel strip in the
‘Output’ screen.
