Universal receiver Model 422LM can be used to operate
two residential garage door openers or entryways with
Model Series 60 code switch remote controls having red
indicator lights, and up to
four Model Series 80 "Smart"
remote controls with green indicator lights.
In general, code switch remote controls are used when
several persons are operating the same device. The code
switches must be set to matching positions in
all remote
controls used to operate the same receiver . (Refer to the
instructions included with Series 60 and 80 remote controls).
Both the receiver and the antenna use TV Type F coaxial
connectors. The antenna can be plugged directly onto the
receiver or mounted to a bracket and connected to the receiver
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.
Children operating or playing with a garage door opener can
injure themselves and others. The garage door could close
and cause serious injury or death. Do not allow children to
operate the door control push button or the remote control
transmitters.
Install receiver (and all door control push buttons) out of the
reach of children and away from all moving parts of the door and
door hardware,
but where the garage door is visible.
This radio receiver incorporates constant closure contacts,
and thus use on residential operators incorporating fail-safe
infra-red sensors is prohibited
