3.0 Configuration / Operating Instructions

3.1

How to use the R247

3.1.1

Activation

Connecting the batteries to the main circuit board activates the R247. The light will

immediately begin flashing and will continue to do so until the unit is no longer required at the

location. Unplug the battery cable from the circuit board to turn the unit off.

3.1.2

Configuration Options

The R247 offers four (4) customer-configurable options using a set of switches located on the

circuit board:

Daytime Brightness Levels: 124, 250 or 400 candela for MUTCD setting.

Nighttime brightness: 10 or 35 candela for MUTCD setting.

Automatic Light Control (ALC): ALC is a patented algorithm built into the system to ensure

that the unit performs at its maximum efficiency by determining the brightness that can be

continuously sustained at a particular state of charge. It will protect the batteries if the voltage

drops too low due to insufficient sunlight. ALC can be turned "on" or "off."

Flash Pattern: See the table in Section 3.2.1 for the 8 options available to choose from.

3.2

Product Configuration

To configure the above settings, the top of the unit upon which the solar panels are mounted

must be removed to access the circuit board inside. To do this, remove the four (4) screws

attaching the top solar panel lid to the main housing. Remove the lid and locate the main circuit

board enclosure in the center of the main housing. Remove the four (4) screws and enclosure

lid.

On the circuit board there is a plastic block with eight small switches on it (see Figure 4).
