4.1.1 MTw LED Indications
The following lists the LED indications of the MTw, which are a combination of the device
states and the Awinda protocol states of the MTw:
State
Description
Power-up
Blinking.
Docked and
fully
charged
ON
Charging
Slow fade from ON to OFF as a percentage [%] of battery status.
A slow cycle means an almost full battery. A quick cycle means an almost
empty battery.
Scanning
Pulsating.
Connected
Slow symmetric ON/OFF toggle in sync with Awinda Station (CONN LED).
Measuring
Fast symmetric ON/OFF toggle in sync with Awinda Station (CONN LED).
Battery Low
Quick Triple Pulses, overrides other states until charging again.
Flushing
Double pulse in sync with Awinda Station (CONN LED).
Stand-by
OFF. Blinks for 3 s, if a change in magnetic field has been detected, while
searching for a radio connection.
4.1.2 MTw Stand-by Mode
Following a wireless connection, the MTw is in operational or measurement mode. When
the radio of the Awinda Master 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, but monitor
change in magnetic field every second. See below for exiting standby mode.
4.1.3 Exiting stand-by mode
With MT SDK 3.8 instead of searching only for a wireless link, the MTw will monitor its
magnetic field once every second. If the magnetic field has changed considerably, and there
is a wireless link to an Awinda Master available, the MTw will automatically become active
again.
To bring the MTw back from stand-by to operational mode, reactivate the radio of the
Awinda Master, 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. As an alternative, this can also be done by
changing the magnetic field around the MTw. Consider moving a pair of stainless steel
scissors (NOT A MAGNET) over the MTw, to change the field and reactivate it.
