Stand-by
OFF. Blinks for 3 s, if motion has been detected, while searching for
a radio connection.
5.7.3 MTw Stand-by Mode
Following a wireless connection to the Awinda Station or Dongle, the MTw enters measurement mode.
If the radio of the Awinda Station or Dongle has been switched off for longer than 30 seconds the MTw
will enter stand-by mode. In this mode, the MTw will shut down its power and stop the LED blinking, but
monitor change in magnetic field every second. See below for exiting standby mode.
5.7.4 Exiting stand-by mode
The MTw will monitor its movement, if there is considerable movement, and there is a signal from an
Awinda Station or Dongle, the MTw will become active again.
To manually bring the MTw out of stand-by mode, reactivate the radio of the Awinda Station, and move
the MTw. A simple 90 degree turn or simply lifting it from the suit case to apply to the subject should be
enough.
