The
STIM RELAY
determines whether the relay on the MR-20 is normally
OPEN
or normally
CLOSED
. Some models of stimulators require one setting and some require the other.
If the stimulator is activated immediately when the stim interface cable is plugged into the MR-20, the
stim relay setting may need to be changed. The
MR-20 is shipped with the relay CLOSED
which
works with the majority of stimulators. Therefore, to change the relay setting choose
B = STIM
RELAY
. The display will now read:
Note the arrow pointing to the closed choice, indicating that this is the current setting. If the closed
setting is desired, pressing the
B = CLOSED
key will keep that mode active. Similarly, if no key is
pressed the mode will not be changed and the screen will soon return to the active EMG display.
To select the open setting press
A = OPEN
. Note that the active selection indicator will shift and now
point to the
A = OPEN
:
This will allow the MR-20 and the functional stimulator to work properly together if the
CLOSED
setting did not work correctly. The relay may be
CLOSED
in a similar manner. In a few seconds the
screen will return to the active EMG display.

If
STIM
is selected as the goal type and the goal or goals have been met continuously for the number
of seconds specified by the
GOAL SUCCESS
time, the stimulator will be activated and the MR-20
display will read:
The number of seconds of stimulation left is displayed and will count down until reaching zero at
which time the stimulation will stop. The duration of the stimulation is determined by the
STIM ON
TIME
. The stimulation may also be stopped at any time during the count down by pressing any key. A
patient rest interval is provided after stimulation is completed. The display will read:
This display will count down the rest interval and then automatically return to real-time EMG activity,
ready to activate the stimulator again when the goal is met.
