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.

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.

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.

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 tempera-
ture 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.

Troubleshooting

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

Power Self-test LEDs Don't Light Up

The charge slot LEDs will light up briefly when first applying power indicating the self-test mode. When
applying power to the unit, all the LEDs will light up. Yellow will show up in the 25% LED for each bay; green for
other LEDs. Then bay #1 will blink a binary representation of the firmware version (V09 = 1001). If the self-test
is not evident:
Remove all batteries, and unplug the charger.
Connect another device to the mains outlet to ensure there is power.
No battery detected.
Battery charging complete. Each LED represents 25% battery
capacity.
Charge in progress. Each LED represents 25% battery capacity.
Battery is not charging due to out-of-temperature conditions.
Unable to read battery, charging timeout, or non Motorola battery.
