The Response Time is used by the MR-20 to smooth or filter the EMG signal. Dynamic training
exercises may require less filtering to see the more raw signal with the individual spikes; this requires
a fast Response Time. Relaxation training may require a smoothed less spiky plot; this requires a
slower Response Time. The
Response Time may be set from 1 - 15 where 1 is the fastest and 15 is
the slowest . The normal MR-20 Response Time is 7 . To set the Response Time , choose B =
RESPONSE TIME .

The MR-20 has two alternative start-up modes available, Demonstration Mode ( Slow Mode ) and
Custom Settings Mode . These are activated by holding down one of the keys while turning the MR-
20 on.

One of the modes is the
Demonstration or Slow mode . All of the menus in the Special Functions
Mode have a time delay during which the choices remain on the screen. The length of time is a
tradeoff between allowing enough time to read the menu and make a selection, and not having to
wait too long to return to the active screen. The standard time was chosen to work well for the
normal user.
However for teaching someone else, or for the beginning user, the menus may not allow enough time.
Holding down the A key while turning the MR-20 on will activate the Demonstration Mode . In
this mode the selection times are significantly longer.
NOTE:
This must be done each time the unit is turned on to be active.
