8 Psion Teklogix CH4000 Quick Reference Guide
4. Cleaning The CH4000
Important: Do not immerse the unit in water. Dampen a soft
cloth with mild detergent to wipe the unit clean.
• Use only mild detergent or soapy water on a slightly damp
cloth to clean the CH4000. Avoid abrasive cleaners, solvents
or strong chemicals for cleaning. The plastic case is suscepti-
ble to harsh chemicals. The plastic is partially soluble in oils,
mineral spirits and gasoline. The plastic slowly decomposes
in strong alkaline solutions.
• To clean ink marks from the label, use isopropyl alcohol.
5. Troubleshooting
5.1 Docking Station Does Not Seem To
Power On.
• When first connected to the DC power supply, the spare
charger LED should turn ON and remain on for 3 seconds.
• If not, the charger is defective and requires service.
5.2 The Ikôn Charge Indicator LED Stays Off.
When an Ikôn is docked into a powered CH4000 and its charge indi-
cator LED stays off, there could be a problem with the Ikôn or with
the docking station. Use an Ikôn with a properly functioning charge
indicator to isolate the problem.
