This message is accompanied by three short beeps from the internal speaker. The message will
shortly disappear and the active EMG will be displayed. At the end of the work period the screen will
show:
This message is accompanied by one long beep from the internal speaker. The message will shortly
disappear and the active EMG will be displayed (so the resting activity can be observed). At the end of
the rest interval the next work period will automatically begin.
The
WORK/REST mode has three parameters which can be set to customize the session for each
application. The work period of each trial can be set between 3 and 180 seconds . The rest interval
between trials can be set between 0 and 180 seconds . The number of trials in the WORK/REST
session can be set between 1 and 20 .
A
WORK/REST mode training session is defined very simply: WHEN THE MR-20 IS TURNED ON
AND THE FIRST WORK PERIOD IS COMPLETED, A NEW TRAINING SESSION IS SAVED IN
MEMORY
. This is true even though the full set number of trials were not completed. For example, if
the session were set up to have 10 trials, but the MR-20 was turned off after the end of the seventh
work period, the saved session would include the data obtained for the 7 completed trials. When the
MR-20 is turned off and back on, the next session will automatically begin.
If the set number of trials is completed, the MR-20 will beep and the display will be:
Turn the MR-20 off when this message appears.
