Cleaning The CH4000
258 Ikôn Rugged PDA (Windows Mobile 6.1) User Manual
7.5.4 Cleaning The CH4000
• 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
susceptible to harsh chemicals. It is partially soluble in oils, mineral spirits and gasoline
and slowly decomposes in strong alkaline solutions.
• To clean ink marks from the label, use isopropyl alcohol.
7.5.5 Troubleshooting
7.5.5.1 Docking Station Does Not Power On
• When first connected to the DC power supply, the spare charger LED should turn ON
and remain on for 3 seconds. If this does not occur, the charger is defective and requires
service.
7.5.5.2 Ikôn Charge Indicator LED Stays Off
When an Ikôn is docked into a powered CH4000 and the Ikôn charge indicator LED stays
off, there may be a problem with the unit or with the docking station. Use an Ikôn with a
properly functioning charge indicator to isolate the problem.
7.5.5.3 Ikôn Charge LED Fast Flashes Green
If the Ikôn charge LED (the left-most LED) fast flashes green when it is docked:
• Remove the Ikôn and disconnect the adaptor DC power cable.
• Wait at least 20 seconds, and then plug the cable in again.
• If the Ikôn LED still shows a fault, the Ikôn requires service.
7.5.5.4 Dock Battery LED Fast Flashes Green With Battery Inserted
• Try inserting a battery that has been tested in another charger and is known to work.
• If the spare charge slot LED continues to fast flash green with the known working bat-
tery, the charger is defective and requires service.
• Your Psion Teklogix battery and desktop docking station are carefully designed for
safety and capacity performance in accordance with IEEE 1725. If the battery or
charger are not Psion Teklogix approved products, or the safety mechanism is faulty, the
spare charge slot LED or Ikôn LED will rapidly flash green.
Important: Do not immerse the unit in water. Dampen a soft cloth with mild detergent
to wipe the unit clean.
