The charger can consume up to 6 A at 120 VAC, 3A at 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
circuit). After unpacking the unit:
• Visually check the charger for damage.
• Install the IEC power cord and apply power.
All charge indicators flash momentarily at power up to indicate that the charger is ready for operation.
If you choose to wall mount the charger, detailed installation instructions are included in the Omnii 6-Slot
Battery Charger ST3006 Quick Start Guide (PN 8000204) included with the charger kit. Be sure to locate
the charger in an area where there is no risk of injury to persons walking in the vicinity.
5.8.2 Operator Controls
The gang charger does not have operator controls or a power switch. There is no dedicated indicator light
to show that the charger is powered, but the charge slot LEDs will light up briefly when first applying power.
5.8.3 Charge Indicators
Each battery charge slot is equipped with four LEDs to indicate the charge status of the battery. When the
Omnii batteries are inserted in the charger, the colour and behaviour of the LEDs associated with the
charging bays in use indicate the status of the charge.
5.8.4 Charging Batteries
• Install the battery with the battery contacts facing the charger. Slide the battery between the guide
rails until it lightly latches in place.
The 4-LED bar for the battery bay shows 25% charger per LED. A flashing green LED shows charging is
under way. The LED directly below the slot in which a battery is inserted lights up immediately. If the
battery temperature is outside 0°C to 40°C (32°F to 104°F), the LED flashes yellow until the temperature is
acceptable. A fully discharged battery will normally take 4.5 hours to charge. At full capacity, it turns solid
green.
When the battery is fully charged, the charger stops applying power; the battery cannot be overcharged if
left in the charger slot.
5.8.5 Troubleshooting
5.8.5.1 Improper Battery Storage
Storing batteries in the gang charger for extended periods (more than a week or two) is not recommended.
Lithium-ion batteries lose capacity if they are maintained at full charge for long periods of time. See the
battery handling recommendations in “The Battery” on page 14.
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.
