NOTE!
***The electronic system is fairly robust and resistant to abuse, but you should never
touch the components or bare wires even when they are disconnected and/or removed
from the dispenser as this may allow electrostatic discharge (ESD) to corrupt stored data or
even destroy a component. ***
Whilst removing or replacing any parts of the electronic system it is good practice to keep
the Power Pack plugged-
in as this may help to ‘earth’ t he system and minimise ESD
problems.
