• Use only mild detergent or soapy water on a slightly damp cloth to clean the RV4000.
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.

Troubleshooting

6.5.5.1 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.

6.5.5.2 EP10 Charge Indicator LED Stays Off

When an EP10 is docked into a powered RV4000 and the EP10 charge indicator LED stays
off, there may be a problem with the unit or with the docking station. Use an EP10 with a
properly functioning charge indicator to isolate the problem.

6.5.5.3 EP10 Charge LED Fast Flashes Green

If the EP10 charge LED (the left-most LED) fast flashes green when it is docked:
• Remove the EP10 and disconnect the adaptor DC power cable.
• Wait at least 20 seconds, and then plug the cable in again.
• If the EP10 LED still shows a fault, the EP10 requires service.

6.5.5.4 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 EP10 LED will rapidly flash green.

6.5.5.5 Dock Battery LED does not Turn On when Battery is Inserted

• 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.
• Try inserting a battery that you know to be working in the charger slot.
