•  Follow all appropriate electrical codes and use only approved electrical 

fittings for the installation. 

•  Choose a wall location that is free of obstructions and permits space for ½” 

NPT conduit runs. 

•  Ensure mounting can support 4 lbs. (1.8 kg) and any additional foreseeable 

load. 

•  Remove the eight (8) cover screws from the front of the unit and carefully 

remove the front cover assembly.  NOTE that the handset and all 
electronics are attached to the front plate.  The front cover may be 
separated from the back box by disconnecting the harness plugs. 

•  Attach the back box to the wall at the desired location using four (4) #8 

screws.  If weather resistance is important in your application select 
washers that will assist in sealing the mounting holes. 

•  Connect cable or conduit (1/2 inch trade size) to the entrance at the bottom 

of the unit. 

•  Connect an approved earth ground to the terminal block. 

•  Bring cable into the enclosure through the conduit entrance and attach 

individual wires from the exchange (Tip/Ring/Ground) to the connector (Tip 
& Ring are not polarity sensitive).  If a conduit hub is used, ensure it is 
grounded to the ground stud. 

•  Apply power to the system. 

•  The HR71 Telephone may be supplied with an optional Auto Dialer or 

dialing may be configured by the PABX.  If an Auto Dialer is ordered with 
the HR71, refer to the manual for the Auto Dialer for instructions on 
programming and for compliances. 

•  Test the unit by calling to and from another unit on the exchange. 

 
 

•  The HR71 Ringdown/Autodialer phone is designed for automatic calling 

simply by removing the handset from the cradle.
