Detect a storm before it happens with this convenient lightning detector. It operates using AAA batteries and will alert you from as far as 40 miles away.

How it works:

The power button is used to select "On", "On with tone" and "Off". Turning the unit on requires simply a short pressing of the button. Pressing the button for approximately two seconds upon power-up enables the tone (a beep will sound indicating that the tone has been enabled). When you want to turn the unit off, simply hold the power button down for approximately four seconds (again, a beep will sound indicating that the unit has shut off).

Battery check:

When first turned on, StrikeAlert performs a battery test. The LEDs will indicate the battery level, with each LED indicating about 20 hours of operation. The LEDs will light up, beginning with the red LED and leading up to the current battery level. The current battery level will be the final LED to light and will remain lit for two seconds. StrikeAlert will then begin its normal operation.

Normal operation:

During normal operation, the green LED will be on continuously to indicate StrikeAlert is monitoring for lightning strikes. If the green LED is blinking, StrikeAlert is in the presence of interference.

Detecting lightning strikes:

When a lightning strike is detected, StrikeAlert will light the appropriate LED indicating the distance of the strike This LED will remain lit for two minutes- unless another strike occurs during that time. If a more recent strike is further away, the LED indicating this distance will light for two seconds, and then return to complete the two minutes from the nearest strike. If a more recent strike is nearer, it will replace the previous LED reading. This LED indicator will be held for two minutes. This allows the user to see all the lightning activity within a 40 mile range, giving clearer visibility to the nearest strike in the last two minutes. If the power switch is in the "On with Tone" position, StrikeAlert will also generate tone(s) indicating the distance of the strike along with lighting the appropriate LED. This allows you to determine the storm's activity without having to monitor the LEDs.

Storm direction:

Strike Alert uses a trend of strike distances over the last five minutes to determine if a storm is approaching, departing, stationary or there is no activity. After the unit has been turned on, holding the button down for two seconds will result with the LED display changing to one of three patterns:

• If the LED cycles from green to red, the storm is approaching
• If the LED cycles from red to green, the storm is departing
• If the LED cycles from the center LED to the outside LEDs, the storm is stationary or there's not enough data to determine the direction of the storm • Direction cannot be determined if there has not been enough strikes to identify a trend or StrikeAlert has not been running long enough
• Approximately five minutes is needed in the presence of lightning strikes to determine direction
