4.3. BATTERY CHARGING WITH THE 3 POSITION CHARGER
4.3.1. The battery pack in the Controller, Remote Units should be sufficiently
charged before use. The 3 Position Charger will charge each unit in about 3-4 hours.
It will take less time for units that are partially charged. Each 3 Position Charger has
three independent charge stations. Each charge station has a CHARGE and a SLOW
light. The 3 Position Charger has a single POWER light. The 3 Position Charger
does not have a discharge function. Two 3 Position Chargers can be employed to
charge all 6 units of the Half Case kit during one charge session.
4.3.2. The 3 Position Charger does not feature a discharge function. To condition
the batteries of the units, they should periodically be left on until the low battery
condition occurs before recharging. A full discharge will help to rejuvenate batteries
that have been stored for extended periods or that may have developed a memory.
4.3.3. Plug the supplied AC Power Adapter into an AC outlet. The AC Power
Adapter will operate from 100-240VAC, 50-60 Hz. The charger itself requires 11-14
VDC @ 2.5A which can also be supplied by an optional 12V auto accessory adapter.
4.3.4. Insert the DC plug from the AC Power Adapter into the power jack on the
side of the charger. The POWER light will turn on.
CAUTION Do not open a vent if there is water on or near the vent. Keep the vents
closed when the relative humidity is above 90%. Take necessary precautions to ensure
moisture does not enter the unit case.
4.3.5. Open the vent on each unit to be charged.
4.3.6. Connect each unit to be charged to the 3 Position Charger. The charger
does not discriminate between Controller and Remote Units; any unit may be
connected to any of the 3 charge connectors.
4.3.7. The CHARGE light for each connected unit will flash for approximately 5
seconds. The flashing CHARGE light indicates that charging is pending.
4.3.8. In normal operation, the CHARGE light will be on steady (non-blinking) after
5 seconds has passed. The steady CHARGE light indicates that the battery is being
charged.
4.3.9. The battery must be within the temperature range 32 ºF and 104 ºF (0 to
+40 ºC) for fast charging to occur.
4.3.10. If the detected battery voltage is less than 6 volts, the battery will be slow
charged until the voltage is high enough for rapid charge. If the battery pack is
defective and the voltage does not rise to the correct level, or if an internal error is
detected within the battery, the green SLOW light will blink continuously.
