18 Maintenance
It is important that the unit is kept clean and dry. It is not weatherproof. Avoid storage in damp
and humid conditions and do not subject it to temperature extremes, excessive vibration or shocks.
Do not stand on the case.
No attempt should be made to gain access to the internal circuitry of the instrument, or its
accessories. Advice should be sought from EA Technology, or the supplier, if any doubt exists over
the equipment's performance or operation.
The unit should be cleaned with a damp cloth. If more heavily soiled, a foam cleanser may be used,
provided care is taken not to allow fluid to enter the instrument. Abrasive cleaners must not be
used.
18.1 Portable Hub
The only user-serviceable part of the Hub is the fuse on the Hub Unit. Use a slotted screwdriver to
remove the fuse if it has blown and insert a new one.
