LED Safety
CAUTION: OPTICAL RADIATION
CAUTION: POSSIBLY HAZARDOUS OPTICAL RADIATION EMITTED (RG-2) FROM THIS PRODUCT. DO NOT STARE AT OPERATION LAMP. IT MAY BE HARMFUL TO THE EYE. (PER IEC 62471 First Edition, 2006-07).
Visual Description: A diagram illustrates a warning triangle containing an eye symbol, with the accompanying text "Do not stare at the operating light source".
The light source of this luminaire (the entire device) is not replaceable. When the light source reaches its end of life, the customer must replace the whole luminaire.
Getting Started: Charging
Charge battery before first use. To access the USB-C charge port on the back of the DEX FingerLight®, insert your fingernail under the recessed portion of the protective cover and gently flip it upward to visualize the charge port. Plug the provided charging cable into a power source, then plug the USB-C end of the charging cable into the DEX FingerLight®. The USB-C charging cable can be used with a charging brick, computer, or any other compatible power source. Charge times can vary. On average, a fully drained battery will take 90-120 minutes to fully charge.
Continuous Battery Runtime
Battery runtime will vary based upon the light modes. The approximate continuous runtimes of each mode on a fully charged battery are as follows:
- Low (dim): 2 hours and 30 minutes (150 minutes)
- High (bright): 45 minutes
- Green (stealth and night vision): 2 hours and 15 minutes (135 minutes)
Once the battery is fully charged, the battery protection circuit will stop charging to prevent overcharging. However, after charging is stopped, the battery will naturally lose a small amount of charge over time due to self-discharge. Bench testing has demonstrated full discharge of the battery will take place after about 70 days.
It is not recommended to leave DEX FingerLight® plugged into the charger for long periods of time after fully charged, as this will reduce the useful lifespan of the battery. Removing DEX FingerLight® from the charger as soon as charging is complete will extend the useful lifespan of the battery.
Battery Charge Indicators
DEX FingerLight® has battery indicators located on top and in front of the power button.
- When the battery is low, the indicator will illuminate SOLID RED, indicating 2-6 minutes of remaining battery runtime, depending upon its current lighting mode. To extend battery runtime, switch to the Low (dim) light mode, or Green.
- PLUG IN IMMEDIATELY AFTER LOW BATTERY INDICATOR ILLUMINATES RED.
- Once plugged in, the battery indicator light will switch to BLINKING WHITE.
- When DEX FingerLight® is fully charged, the battery indicator light will illuminate to SOLID GREEN.
NOTE: DEX FingerLight® will not operate while charging.
Usage Instructions
Flexible Ring Operation
To adjust the Griptonite TPU Overmolded Copper Ring, manually expand the ring to fit over the desired finger or thumb, then squeeze the ring to fit the finger or thumb comfortably. Refer to the Quick Start Guide included in the packaging or visit our website.
Light Operation
The power button located on the top of the DEX FingerLight® is indicated by the icon logo with a raised ring around the outside. There are three lighting modes that occur with each power button press:
- Low (dim)
- High (bright)
- Green (stealth and night vision)
After Green, the next button press will cycle off.
Mode Memory
Once the preferred lighting mode is selected, Mode Memory will automatically engage after three (3) seconds, at which point the light will turn off instead of cycling to the next setting. From "off," pressing the button will turn the light to the same setting. To go to a new setting, the button must be pressed within three (3) seconds of turning on the light. Mode Memory will reset when DEX FingerLight® is plugged-in to charge.
General Use
DEX FingerLight® is indicated for use as a finger-mounted illumination device. Its intended use is for hands-free tasks and can be worn in any position.
DEX FingerLight® is waterproof up to an IP57 rating, which means it can be submerged for up to 30 minutes at a one (1) meter depth and also resistant against dust and dirt ingress.
To clean the surface of the DEX FingerLight®, use a damp cloth with water or isopropyl alcohol and apply light pressure.
Important Precautions
- DO NOT use DEX FingerLight® in a combustible environment.
