1. When mounting in a Model 234 Series Stanchion or for flush-mount installations, the supplied back
box must be used to mount the Model 277-001 Telephone. Mount the back box to the structure using
appropriate hardware.
2. If mounted outdoors, install a telephone line suppressor (customer-supplied) on the telephone line.
3. Remove the tapered plug from the back cable entry hole in the back box, and install the telephone line
(customer-supplied) and cable fitting.
4. Recommendation—use silicone sealant or equivalent around and inside all conduit entries.
5. Connect the modular connector of the 7-foot supplied telephone cord to the incoming subscriber line
or the telephone line suppressor (if applicable) using the appropriate mating connector.
6. Attach telephone’s front panel to the mounting flanges of the back box using the six supplied #10
security screws and the six black flat washers. A Model 233-001 Security Screwdriver (sold
