If the unit requires cleaning, then only clean exterior with
a damp cloth to avoid electro-static charge build up.
If a unit fault should occur, then the unit can be repaired
by MEDC.
If you acquired a significant quantity of units, then it
is recommended that spares are also made available.
Please discuss your requirements with the Technical Sales
Engineers at MEDC.
