Installing your Automatic Electric Model 50 Wall Phone

This phone was made prior to the development of the modern wall jack. In the days when this phone was installed, they mounted the phone to the wall directly over the hole where the phone wires come out and then wired the phone directly to the house wiring. This is referred to as ďhard wiredĒ (as opposed to modular).

You have two options to mounting your phone. You can secure it to the wall anywhere and run the line cord included to the nearest jack, or you can mount the phone directly over an existing wall jack. Iím including instructions for both, but first instructions on opening up your phone.

Removing the cover
To remove the cover of your phone, unscrew the button that the handset rests on. This is the switch hook and should only be finger tight. When putting the cover back on, finger tight again is enough. Remember that this phone is made of Bakelite and is fragile. Cranking down on screws can start breaking things.
After the switch hook is removed, loosen the two screws on the front of the phone and slide the cover off.

Mounting the phone
Inside you will see holes in various places for securing the phone to the wall. I recommend using at least three points. How you secure it to the wall depends on the wall material you are going into. I recommend toggle bolts on drywall for best holding power. If youíre not sure what to use, ask at any home store for a fastener that will hold 6 to 8 pounds to the wall securely.
To mount the phone over an existing wall jack, follow these instructions.
  1. Remove the wall jack from the wall and disconnect the wires from it (you canít get shocked, itís all low voltage). Wrap the yellow and black wires back out of the way, you will not need them. You will only be using the red and green.
  2. If you have two wires coming from the back of the phone, you can attach your house wires to these. If there is a line cord, then remove the line cord, making note of which screws the wires were attached to. Color matching doesnít matter so long as you use the correct two screws.
  3. Mount the phone to the wall threading the wires through the hole in the back of the phone. Attach the red and green wires to the terminals.
  4. Put the shell back on the phone and give it a try. Remember, no real tight screws, snug is good enough on Bakelite.
  5. When putting the shell back on, be sure to watch out for the dial wires near the top. There isnít much room for them and you donít want them getting pinched.

Adjusting the ringer
When at itís maximum, the ringer in this phone can wake the dead. To adjust this, remove the cover of the phone and look at the bells. You will see a screw in the center of each bell. You will also notice that the hole this screw goes through is not exactly centered in the middle of the bell. Loosen the screw enough so you can rotate the bell. The further you move the bell away from the clapper, the softer the volume will be.
To test the ringer with the cover off the phone, screw the hook switch back into itís place on the metal bracket and push down on it to ďhang upĒ the phone. Call your number and you can adjust the volume as the phone rings. One thing to keep in mind, ringing voltage is 100VAC. It wonít hurt you, but it will get your attention, so watch where youíre putting your fingers when testing the ringer.
