Speck Electronics MicPre 5.0 - Manual (Page 13)

The front panel is a high quality painted surface and the panel
lettering is applied using a silkscreen printing technique.
To clean the front panel, wipe the surface gently using a soft lint-
free cloth to avoid scratching the panel or markings. Paper towels
are not recommended. Commercially available window cleaner
solutions may be used; however, the solution should be applied to
the cloth and not the panel to avoid the seepage of liquid to the
inside of the enclosure.
If the MP 5.0 is to be shipped to Speck Electronics for service or
repair, attach a tag to the product identifying the owner and
indicating the service or repair to be accomplished. Include the
model number and serial number of the product. Place the product
in the original container if available. If the original container in
not available, a suitable one can be purchased from Speck
Electronics.
If the original container is not used, wrap the product in heavy
plastic before placing in an inner container. Use plenty of packing
material around all sides of the product and protect panel faces
with cardboard strips. Mark shipping container with "Delicate
Instrument" or "Fragile", and insure the shipment for the proper
amount.
Note: Speck Electronics cannot be responsible for equipment that
arrives damaged or uninsured.
