:Payphone Repair Procedures:
                          --------------------------

Payphone Repair Tools:

The following is a suggested list of items to efficiently service payphones:

-Keys to payphone

-T-key

-Various screwdrivers (phillips & flat blade)

-Hammer

-Wire cutters

-Wire strippers

-Neddle nose pliers

-Regular pliers

-Line man's test set (butt-set)

-Some type of cleaner such as Windex®

-Role of paper towels

-One each of the following known working parts:
  Relay, Keypad, Hopper, Handset, Coin mech, cradle, coin return lever,
  spare battery, and line board.

-Multi-meter (optional but comes in handy)

-5-each nickles, dimes, quarters for testing.

Any additional tools and supplies are helpful but the above list is almost
esential if any type of repair is needed on the payphone.

Coin Jams:

Since most payphone owners are now charging 35 cents for initial rate, more
dimes are being used to formulate this amount (one dime and one quarter).
Coin mechs, especially mechanical ones, have always had more problems
accepting dimes, mostly because of their weight.  It is essential, more than
ever, coin mechs are kept clean.  A dirty coin mech is the main problem that
cotributes to coin jams.

"No Dial Tone" Trouble-shooting:

If you pick up and listen to your handset and do not hear dial tone follow
the steps below:

 1) Connect butt-set to tip & ring (phone line) at the terminal block in the
    lower housing.  If you still do NOT have dial tone go to step 2.
    Otherwise continue thru this step.

    If you have dial tone at this point your problem is in your phone.  Make
    sure that the phone line connection to your board is OK, check that the
    keypad plug is secure into the socket on the board, also ensure that all
    hand set wires are properly connected to the keypad.  If this is OK try a
    known good handset, next a known good keypad, and last, either the
    battery on your board or the board itself.  If you have a known good
    keypad and handset hooked together you can try this and eliminate
    problems with components in your upper housing.

 2) Disconnect your phone (at the terminal block) from the telco line.
    Connect your butt-set to the phone line.  If you get dial tone there is
    something wrong with your phone.  The handset may have a short.  If you
    still have NO dial tone go to step 3.

 3) Go to the dmark (station interface) and check for dial tone there with
    your butt-set.  If you get dial tone at this point but not at your
    payphone the problem is probably with your station wire.  Before
    replacing the wire make sure that connections inside your phone and at
    the dmark are secure and not corroded or broken.  If you still do NOT
    have dial tone go to step 4.

 4) Disconnect your station wire from the dmark.  Hook butt-set on line
    terminals.  If you get dial tone at this point there is a problem with
    your wire.  If you still do NOT have dial tone go to step 5.

 5) Hook up your butt-set to the telco side at the dmark.  Make sure all
    connections except the telcos are disconnected.  If you do NOT get dial
    tone here the problem is with the telco not your phone, since you have
    nothing connected to the line it is not a problem you can repair.  Call
    your telco and report the problem.

Note: Even though this seems like a long process most of the steps can be
performed rather quickly to determine where the problem is located.
Following this procedure can save you money by not calling the telco out for
a problem that is really yours.  This same procedure should be used for noisy
lines.  Always remove your equipment from the line to be sure the problem is
with the telco before calling them.
