D. LED lights meaning during play
1. Blinking Green light indicates that the device is switched on.
2. Blinking Amber light indicates that the device is on but on low battery. The device can still work for about
2 hours.
3. Flashing Yellow light indicates a moderate impact. Recommended to be removed from activity ASAP
and assessed for injury before resuming play.
4. Flashing Red light indicates a more severe impact. Recommended to be removed from activity ASAP
and assessed for injury before resuming play.
5. To reset the Yellow or Red flashing lights, turn off the Checklight device by pressing the OFF button for
4 seconds, and turn on the device by pressing the ON button for 4 seconds when the player is cleared to
resume activity.
E. Retrieving impact count after play
1. Connect the Checklight device to the USB power cord and insert the other end of the power cord to an
electrical outlet.
2. Then disconnect the Checklight device from the USB power cord. (Does not need to be fully charged)
3. The device will report impact counts in 100s for ‘less severe’ (Green) impacts and every ‘moderate’
(Yellow) and ‘more severe’ (Red) impacts it has received.
IF…
the device has sustained LESS than 100 (green) ‘less severe’ impacts, and no (yellow) ‘moderate’ or
(red) ‘more severe’ impacts, then NO light will blink.

Or else…
the three LED lights will blink all at once, and then blink in a series to indicate the impact count for
green, yellow and red impacts in the following order:

GREEN – the green light will blink once for every 100 ‘less severe’ impacts recorded, e.g. it will
blink twice if the device received 200-299 ‘less severe’ impacts. Once the green light has
finished displaying, all three lights will blink once simultaneously.

YELLOW – next the yellow light will blink once for every ‘moderate’ impact recorded. Once the
green light has finished displaying, all three lights will blink once simultaneously.

RED – finally the red light will blink once for every ‘more severe’ impact recorded.
