Charging the Battery:
Duration:
The Wireless Firefly Otoscope has a built-in high efficiency lithium battery that enables more than
2.5 hours continuous operation.
Charging the Battery:
Through the mini-USB port at the rear of the otoscope, the embedded battery can be charged
with the provided USB DC cable. The cable must be connected to the USB port of a PC or to the
“USB Power Adapter”, which can charge directly from a wall outlet.
Overload Protection:
The overload protection circuit will prevent overcharging when the battery is full and the
“Indicator” will turn green.
Power Indication:
The power indicator light is normally red during operation, but it will turn blue when the
remaining battery life is less than 30 minutes.
The lithium battery is a delicate and consumable item. It is expected to last through years of
use and is guaranteed for twelve months from its purchase against defects. If there is any
battery related issue, please contact customer service immediately. Battery replacement by
unauthorized personnel or replacement with unauthorized batteries may damage the system and
voids the overall warranty.

switch allowing users to set the wireless channel.

the same channel for proper operation:
