EP10 Charge Indicator LED Stays Off

When an EP10 is docked into a powered RV4004 and the hand-held charge indicator LED stays off, there
may be a problem with the EP10 or with the docking station. Use an EP10 with a properly functioning
charge indicator to isolate the problem.
6.6.5.2

Power LED Does Not Light Up

• Remove all the EP10s, and unplug the docking station.
• Connect another device to the mains outlet to ensure there is power.
• Remove the IEC mains power cable from the charger, and check it for damage.
• Reconnect the mains cable in the charger and mains outlet.
6.6.5.3

EP10 Charge LED Flashes Yellow

A flashing yellow EP10 charge LED (the left-most LED on the hand-held) indicates that the battery is not
within the allowable charging temperature range — 0° C and 40° C (32° F to 104° F). Allow the battery to
come to an acceptable range before reinserting the EP10 in the docking station.
6.6.5.4

EP10 Charge Indicator LED Flashes Red

If the EP10 charge indicator flashes red when the EP10 is in any of the four sites, the quad dock cannot read
the battery or it is a non-Psion battery.
• Remove the EP10s and disconnect the adaptor DC power cable.
• Wait at least 20 seconds, and then plug the cable in again.
• If the EP10 indicator still shows a fault, the EP10 requires service.

Powered Adaptor LED Stays Off

• Check the AC cable. Replace with the same type if the cable is suspect.
• If the adaptor LED stays OFF, the adaptor is defective and requires service.

6.7.1

Charging the EP10 Battery

Quad Battery Charger (Model No. RV3004) can charge up to four batteries simultaneously.
6.7.2

Installation

The charger can be wall mounted using the wall mount bracket (model number RV6009) or it can be oper-
ated on a flat surface. Install the charger in an area that is free from excessive dirt, dust and contaminants.
The ambient temperature must be in the range 0° C and 40° C (32° F to 104° F). The charger will not
charge batteries outside of this temperature range. For maximum performance, it is recommended that the
charger be operated at room temperature – a temperature range between 18°C to 25°C (64°F to 77°F).
The charger can consume up to 1.5 A at 100-240 VAC. Check to ensure the mains circuit supplying the
charger is adequate for this loading (especially if several chargers are being powered from the same cir-
cuit). After unpacking the unit:
• Visually check the charger for damage.
• Install the IEC power cord and apply power.
Important: Use IEC-320 C13 power cords approved by Psion, with the ground pin connected
to a proper earth-grounded receptacle. Check with a qualified electrician if you are
uncertain of your receptacle grounding.
All charge indicators flash momentarily at power up to indicate that the charger is ready for operation.
