HL7R Instructions:
Battery Installation
The HL7R uses three AAA NiHM rechargeable 1.2 volt batteries.
The batteries are housed in the rear of the headlamp.
To access the battery compartment, pull the elastic head band slightly away from the battery
pack.
Remove the rubber battery case cover by grasping the tab at the top of cover and pulling it away
from the battery pack.
Insert the batteries in the direction indicated inside the battery pack.
Replace rubber battery case cover, making sure that the cover is paced evenly over the rim of
the case.
Charging Instructions
Prior to first use, charge the HL7R at least eight hours.
The headlamp can be charged via USB or a standard AC power outlet.
To charge via USB, insert the charging cord into the small box near the battery pack that is
marked “DC IN 5V.” Insert the USB end of the cord into a USB port on a computer. The
computer must be turned on to charge the headlamp.
To charge via AC wall outlet, plug the USB end of the cord into the supplied AC adaptor. Plug the
AC adapter into the AC power outlet.
When the light is charging, a green light will be visible flashing in the lens of the light. When the
headlamp is fully charged, the light will stop blinking and stay on green.
