Troubleshooting
226 Ikôn Rugged PDA (Windows CE 5.0) User Manual
• 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. 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.
6.5.5 Troubleshooting
6.5.5.1 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.
6.5.5.2 The Ikôn Charge Indicator LED Stays Off.
When an Ikôn is docked into a powered CH4000 and its charge indicator LED stays off,
there could be a problem with the Ikôn or with the docking station. Use an Ikôn with a prop-
erly functioning charge indicator to isolate the problem.
6.5.5.3 The Ikôn Charge Indicator LED Is Fast Flashing Green.
If the Ikôn charge indicator fast flashes green when the Ikôn 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 indicator still shows a fault, the Ikôn requires service.
6.5.5.4 Spare Battery LED Fast Flashes Green With A Battery Installed.
• Try inserting a battery that is known to be working with another charger.
• If the charge slot LED continues to fast flash green with the known working battery, 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.
6.5.5.5 Spare Battery LED Does Not Turn On When A Battery Is Installed.
• Inspect the charge slot contacts for damage (are they bent, flattened, twisted or
broken?).
• Reinstall the battery and check that it is fully seated in the slot.
