Cleaning the ST4004
Use only mild detergent or soapy water on a slightly damp cloth to clean the ST4004. Avoid abrasive clean-
ers, solvents or strong chemicals for cleaning. The plastic case is susceptible to harsh chemicals. The plastic
is partially soluble in oils, mineral spirits and gasoline. The plastic slowly decomposes in strong alkaline so-
lutions.

The Omnii Charge Indicator LED Stays Off
When the Omnii is docked in a powered ST4004 and the hand-held’s charge indicator LED stays off, there
may be a problem with the Omnii or with the docking station. Make sure a battery is installed in the Omnii,
otherwise use an Omnii with a properly functioning charge indicator to isolate the problem.
