number of
trials may be set from 1 to 20 trials

return to the active EMG display.
The MR-20 has a
default WORK PERIOD of 10 seconds

To use the MR-20 to control a stimulator, the stimulator must be configured properly and the MR-20
must be connected via the stim interface cable. Basically the stimulator is set to be controlled by a
switch connected to its accessory input jack. The MR-20
STIM OUT
jack provides the switch
connection.
For the MR-20 to be able to control the stimulator, there are settings on the stimulator itself which
must be correct. The
stimulator must be configured with the ON TIME set for the maximum, the
OFF TIME set for the minimum, and set to CONTINUOUS stimulation.
Once it is verified the stimulator is working correctly, plug one end of the stim interface cable into the
stimulator accessory jack and the other end into the STIM OUT jack of the MR-20. The stimulator
should now be controlled by the MR-20 in the stim feedback mode.
If the stimulator is
ON
when it should be
OFF
, change the polarity of the stim relay in the MR-20
Special Functions mode (Refer to the Stim Relay section). If the stimulator is not working correctly
contact the dealer or manufacturer of the stimulator.
The stimulator cycle is composed of three time periods.
