The A key is used to set the feedback mode for EMG A and the B key for EMG B. Since the EMG A is
the controlling channel, set up the mode for EMG A first, then EMG B. By pressing the A key once, the
current mode will be momentarily displayed on the EMG A channel. In this case the display will read
NO GOAL SET. To change the mode simply press the A key again until the desired mode is displayed.
When no keys are pressed for a few seconds, the MR-20 will return to the real-time EMG display.

Feedback mode choices are:
1)
A = ABOVE TONE
-- audio feedback when contracting above goal,
2)
A = BELOW TONE
-- audio feedback when inhibiting below goal,
3)
A = ABOVE STIM
-- stimulator activation when contracting above goal,
4)
A = BELOW STIM
-- stimulator activation when inhibiting below goal,
5)
A = MAX DISPLAY
-- the maximum value measured is displayed in the digital display until reset by
a keypress,
6)
A = RATIO A/B
- the ratio of EMG A divided by EMG B is displayed.
The B key has the first five choices plus one additional:
B = CHANNEL OFF
. Select this mode
if only
EMG A is to be utilized
(single channel mode).
NOTE:
The EMG A channel is the controlling channel for feedback modes. If a
STIM
feedback mode
is
selected for the EMG A channel, the EMG B channel cannot be in a
TONE
mode
. Similarly, if a
TONE
mode
is selected for the EMG A channel, the EMG B channel cannot be in a
STIM mode
. Therefore
always set the A channel to the desired mode first.
