Safety
The BRC40/22 (Armada) uses 120VAC as a power source, proper precautions must be used to prevent electrocution. It
is important to unplug the device when performing repairs however, much of the troubleshooting must be performed
with the device plugged into a power source to perform component testing. When electrical troubleshooting is required
on any piece of equipment the use of insulated tools is required. The capacitors on the control board do not discharge,
it is important to take care when handling the controller to not touch the back side of the board.
ESD Protection
Most of the equipment manufactured today use modern computerized technology and computerized circuit boards.it is
important to use ESD (Electro Static Discharge) protection when working on equipment to prevent damaging the Inte-
grated circuit chip within the printed circuit boards.
