Cleaning

The TOF-Watch case may be cleaned with a damp cloth. Thorough cleaning of the device can
be achieved by using a cloth moistured with either 70% ethanol, methanol, a chlorohexidine
solution or 0.5% hypochlorite. Other chemical cleaners may damage the case finish and are
not recommended. Do not use abrasive cleaners as these will damage the surface.
Do not allow liquid to enter the case.
7.2

Unusual patterns

"Persisting responses" - Direct stimulation:
If the thumb is influenced by direct stimulation of the muscles under the stimulation electrodes
this can result in an apparent response which does not disappear.
To eliminate this phenomenon the hand must be fixed in such a way that the muscle
stimulation does not result in a movement of the thumb. Alternatively try changing polarity or
position of the electrodes or try to lower the stimulation current.
Note: The TOF-Watch can show twitch responses higher than 100%.
Large twitch responses may occur especially when no calibration has been performed or for a
brief period of time after administration of a depolarizing relaxant.
