WARNING -

environment over 60 degrees Celsius or 140 degrees Fahrenheit.
The Lithium-Polymer internal batteries (7.4V 5200mAH) should be replaced every five years
with a Firelinx-approved battery (go to

batteries should last 8-12 hours. For best battery performance, store at 40% to 50% battery
capacity. Do not store the unit plugged into the charger. A second battery pack may also
be installed if needed. If a second battery is installed, there will not be enough room to install
an Open Pyro Network (OPN) expansion card.
