Charging Battery:
Duration:
The Wireless Firefly Microscope has a built-in high efficiency lithium battery that enables more
than 4.5 hours continuous operation.
Charging the Battery:
Through the mini-USB port at the rear of the microscope, 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

WIRELESS INTERFERENCE RECOMMENDATIONS
Last reviewed: January 27, 2011.
Many wireless products, such as cordless phones, home networks, Bluetooth devices, and baby monitors,
share the 2.4-GigaHertz (GHz) radio frequency bands. As a result, these products are likely to interfere with
each other. Interference might generate noisy images and degrade the video quality on the Wireless Firefly
Microscope.
Here's what you need to know to minimize interference:
Interference immunity from cordless phones
Most 2.4GHz cordless phones use frequency hopping spread spectrum (FHSS) technology that operates
within the 2.4-GHz spectrum. FHSS hops from frequency-to-frequency across the entire 2.4GHz spectrum.
The wireless Firefly Microscope and 802.11 WiFi wireless networks, on the other hand, use direct sequence
spread spectrum (DSSS), which transmits within only a part of the 2.4 GHz spectrum. Because FHSS jumps
across the entire spectrum while DSSS stays in only one portion, a FHSS 2.4GHz product can cause
interference with the Wireless Firefly Microscope.
Choose a cordless phone that uses the 5.8-GHz, 1.9-GHz, or 900-MHz band
These frequency bands are not as widely used as 2.4-GHz and, therefore, are less likely to cause or receive
interference. If you want a multiple-handset-capable cordless phone with handset-conferencing capability,
choose one that uses only the 5.8-GHz or 1.9 GHz band. By contrast, nearly all phones using 2.4-GHz digital
spread spectrum (DSS) technology and those that allow handset conferencing may create interference in
other products, some even while in standby mode.
actually use both the 5.8-GHz and 2.4-GHz bands. DSS phones labeled as "wireless network friendly" or
"802.11-friendly" are unlikely to interfere with wireless computer networks, but they may interfere with the Wireless
Firefly Microscope and other wireless devices. Keep the 2.4-GHz analog phones as far away from the area as possible.
Be aware that some cordless phones labeled as 5.8-GHz
Lower the antenna position of cordless phone
If relocating or replacing the phone is not an immediate option, operate the cordless phone with the
antenna in the lowered position if possible. This will dampen the RF signal coming from the cordless phone
and reduce the amount of interference.
Keep your distance
After above adjustment, try keeping the conflicting cordless phone as far away as possible, such as in
different rooms.
Interference immunity from wireless networks
Like most wireless products, the wireless Firefly Microscope allows you to operate at 4 separate channels
(residing on frequency range index of 2414, 2432, 2450 or 2468±10 MHz).

User Manual for Wireless Firefly Microscope GT600 Version: 1.0
The 802.11 wireless networks use direct sequence spread spectrum (DSSS), which transmits within
approximately one third of the 2.4 GHz spectrum, and it is possible to change the channels of 802.11
networks on a wireless router by entering the administration mode.
Change Access Point or Wireless Router channels
Normally the WiFi wireless network router or access point uses #6 as the default channel, which is located
in the center of the 2.4-GHz spectrum. This can easily conflict with the wireless Firefly Microscope’s
spectrum. Try changing the channel on the access point (i.e. 1, 6, and 11). Anecdotally, users have
found they have the least interference on channel 11 while the wireless Firefly Microscope’s channels are
set to 3 or 4.
Change the relative location of the Access Point
Maximize the distance between the wireless Microscope and WiFi devices.
Fine tune the position of the compact receiver
Try different angles on the compact receiver. A flat horizontal orientation or vertical orientation may
produce better results.
Interference is an unfortunate byproduct of numerous wireless products today. While there
are no guarantees the actions above will work, they may reduce interference to acceptable
levels.
