Opening and Closing 
To open, use a screwdriver to push down the tab that 
holds the transmitter cover and mounting base 
together. Pull the mounting base away from the cover, 
starting from the top. 
To close, connect the bottom of the transmitter first, 
and tilt the top forward to close the tab. Closing the 
transmitter starts it up if power is supplied to the screw 
terminals.
