Detection Pattern
    Eight 1.5V size AA batteries (not included) are located in the rear 
section of the Control Housing. The batteries are sealed off from 
the electronics so that accidental water leakage into the battery 
compartment will not damage the circuitry. 
1.  Remove the battery cover by partially unscrewing the 
two knurled thumb screws with a coin. (The knurled knobs 
are “captive screws” and are not to be removed from 
the battery cover.) 
2.  Remove the battery pack from the Control Housing and 
disconnect the battery lead connector. Be very careful 
not to put any undue strain on the battery leads. 
3.  Remove the batteries from the battery packs. Note 
the polarity markings inside the pack and install fresh 
batteries. 
4.  Reconnect the battery lead. 
5.  Insert the battery pack into the Control Housing with the 
connector toward the top of the compartment.  
6.  Make sure the O-Ring and both sealing surfaces are 
clean before reinstalling the battery cover.
