SPECIFICATIONS FLASH CODES
RECYCLING
If the battery is ≤14%, low voltage disconnect (LVD) disables the LED and attempts to
charge the battery to a sustainable SOC. The LED is re-enabled once SOC is >75%.

AUTOMATIC LIGHT CONTROL
During periods of sustained poor solar charging, Automatic Light Control (ALC) may
decrease LED intensity based on battery SOC and recent charging trends. When
solar charging returns to a sustainable level, ALC increases intensity back to the user
setting. ALC may be disabled to keep the lantern at a constant intensity.
Enable ALC: 801Disable ALC: 800
In “on” mode, the OL2A LED turns on at night and off during the day. The lantern
charges in sunlight, but the LED remains off when in “off ” mode. When turned on again,
the lantern activates at its last programmed settings (1 minute preview for daytime
activations).
Option 1: Switched Models
Set the switch to on or off
position
Option 2 : IR Programmer
Using the IR programmer, enter:
The batteries are best charged inside the lantern. The OL2A can recharge 0 V or 0%

The OL2A comes with 3x AA industrial-grade, high-temperature NiMH batteries. The
OL2A will only operate with all 3x batteries installed correctly. The lantern remembers
its settings even when the batteries are removed.
Other rechargeable AA NiMH batteries will not void your warranty. However,
shock, vibration, temperature and optical performance may be limited.
To install batteries:
1. Install batteries noting their polarity.
2. Apply a thin coat of silicone lubricant to the large sealing
o-ring.
3. Align top cover and assembly components; secure with
the provided screws. Do not over tighten!
BATTERY INSTALLATION
Do not use a battery charger with >370 mA charge rate. High charge rates will
over heat the batteries and cause internal damage.
Take care when charging using a lamp. Provide air circulation or a fan so that
lantern and batteries do not exceed max. temperature.

AUTION
Summer sunlight 8-12 hours
Winter sunlight 18-36 hours
60 W incandescent lamp 15-36 hours
Although the OL2A is maintenance-free, performance gains can be made. Clean with
water and a soft sponge or cloth. A mild non-abrasive cleanser can be used for more
stubborn residue. Clean more frequently during drier months as dust accumulates more
quickly. Check the exterior and o-rings for cracks and missing or broken hardware.
• If a lantern detects continuous dark for 24 hrs., like when it’s inside packaging for
shipping or storage purposes, it will disable the LED. Upon sensing light, it will
enable the LED and continue normal operation.
• Check the battery state of charge every 1 - 2 months and charge if required.
• High-grade NiMH batteries shipped with the OL2A can be stored without any
charging for up to 12 months with no battery damage.
STORAGE
TROUBLESHOOTING
Turn the lantern off to store. In switched models, set the switch to the “off ” position. To
turn off using the IR programmer, press and hold for 4 seconds.
