Maintenance
9.1. General
The ExpressCube™ countertop unit is a sealed certified device that does not require any internal
periodic maintenance. In the event that the unit has incurred physical damage that may affect the
operation of the unit, it should be sent back to an authorized service center for repair and re-
calibration.
9.2.
Cleaning (Excluding the Sensor Lenses)
To maintain the optimum performance of the ExpressCube™ countertop, the unit should be
periodically cleaned to remove any build-up of dust and dirt. The black metal areas should be
cleaned separately from the sensing strips. Use a damp cloth with a mild detergent and rinse with a
clean damp cloth. Hand pumped sprayers can be used. Apply a non-corrosive cleaner to stubborn
areas but care should be exercised to keep spray from the sensor strips.
"
Do not use any volatile liquids to clean the surface. This is an electronic device and
trapped fumes in the enclosure could be ignited by the electronic circuitry.
"
Do not use any pressurized liquid source (e.g. water hose, steam jet, etc) to clean the
unit.
9.3.
Cleaning the Sensor Lens
It is important to keep the sensor lenses clean and free from any debris that may obscure the
package from sensors. Use a soft clean cloth with commercial glass cleaner to clean the surface of
the lens.

Do not use abrasive or dry cleaners on the lens.
