The 9vBRLT replaces the battery in most engines. This unit is intended for use with Lionel type systems, which have no charging circuit, and all others utilizing their system such as Atlas, K-Line, 3rd Rail, and Weaver. These systems all require the use of a 9 volt battery. Similar size to that of a 9 volt battery so that it can fit into most small places. Since the 9vBRLT does not require any maintenance, you can also install the 9vBRLT inside the shell of an engine instead of the compartment initially made for the 9 volt battery. Installation is simple but does require connecting one wire to the center roller pickup wire. Operation requires a minimal amount of user input. Initial charge of the 9vBRLT occurs in the first 30 seconds. After full charge is achieved, all low voltage operations are achieved without the loss of sounds for several seconds (time is determined by how well charged the 9vBRLT is). If the locomotive has been sitting idle for more than a few hours simply recharge the unit.

The 9vBRTV is intended to power TV camera transmitters, or other light current devices, requiring 9 volts DC. This electronic circuit, the 9vBRTV, replaces the battery in TV type camera transmitters. Install the 9vBRTV by connecting it's input power to either AC, DC, DCC, or other voltages to obtain the fixed 9 volt output. To maintain the 9 volt output, sufficient input voltage must be present. The 9vBRTV contains on board storage which prevents intermittent connections of the track power from affecting the cameras operation!
