All GoBe lights have an SOS mode built in. For the GoBe S models the SOS mode can be operated by using the button.
Step 1: Start with the light head in the off position.
Step 2: Push and hold the power button down until the light head comes on in the lowest stetting. Once the light comes on, release your finger from the power button.
Step 3: Push the power button once to enter into SOS mode. At this point the light should begin to flash.
Step 4: To exit this mode push and hold the power button down for about 2 seconds until the light head stopped flashing.
Note: If you continue to push the power button down until the indicator light flashes red, you have entered into travel lock mode. To exit travel lockout mode push and hold down the power button again until the indicator light flashes green and release your finger. You should be able to turn the light head on like normal from this point.
