The Pro900 has two options for powering the transmitter; AC mains power or internal batteries. The AC adapter is useful when 120 Vac power outlets are available nearby. The adapter provides constant power and does not diminish batteries. To use the AC adapter, simply insert the round plug of the adapter into the “12 V” external power receptacle on the transmitter panel and the traditional bladed end into a wall outlet. The transmitter is then powered by AC mains voltage instead of batteries. The Pro900 transmitter also can use 8 “D” (LR20) alkaline batteries that are installed inside the transmitter battery compartment. Remove the battery compartment cover and install the batteries, paying particular attention to the positive and negative poles.
A 9-volt square (6LR61) alkaline or lithium battery is needed for the Pro900 receiver. It is important that the 9V battery is either alkaline or lithium. Do not use a zinc carbon 9V battery. To install this battery, remove the battery compartment cover located on the back top portion of the Pro900 receiver with a flat-head screwdriver. Install the 9 volt battery by connecting it to the battery snap boot inside the battery compartment. Don't yank or pull xxxx the battery boot. Finally, replace the battery cover.
