In general, code switch remote controls are used when

switches must be set to matching positions in all remote
controls used to operate the same receiver. (Refer to the

with Model 86 Coaxial Cable Kit, if you need more range.
Select a location for the receiver which allows access to the
terminals and space for the antenna (as far from metal structures
as possible and preferably with the antenna in an upright
position). Fasten the receiver securely with screws through the
two holes provided in the cover flanges.
