SILVER BOX

A SILVER BOX ADDS FOUR TONES TO YOUR
TOUCH-TONE PHONE.

MATERIALS: 1. THREE PIECES OF WIRE EACH
              ABOUT A FOOT LONG
           2. MICRO SPDT TOGGLE SWITCH.
              (RADIO SHACK # 275-625)
           3. TOUCH-TONE PHONE

PROCEDURE:
   1. IF YOU DO NOT KNOW ABOUT ANY ELECTRONICS OR PHONES DO NOT EVEN
      ATTEMPT THIS!!!  IT COULD RUIN YOUR PHONE PERMENTLY!
   

   2. TAKE THE CASING OFF YOUR PHONE.
   

   3. LOOSEN THE SCREWS ON THE SIDE OF THE TOUCH-TONE KEYPAD THAT HOLD
      IT TO THE MOUNTING BRACKET ANd CAREFULLY REMOVE THE KEYPAD.
   

   4. YOU WILL NOTICE A PLASTIC COVER ON THE KEYPAD.  SEPARATE THE TWO
      HALVES AND GET THEM OUT OF YOUR WAY.  DO NOT DESTROY THEM THOUGH.
   

   5. LOOK AT THE TOP ROW OF THE KEYPAD SO THAT THE 1-2-3 ROW IS FACING
      AWAY AND THE *-0-# ROW IS FACING TOWARDS YOU. TURN THE KEYPAD OVER
      BRINGING THE RIGHT SIDE UP AND OVER.
   

   6. YOU SHOULD SEE A BUNCH OF WIRES, GOLD PLATED CONTACTS, ELECRTONIC
      COMPONETS, AND TWO BLACK CYLINDERS.  THESE ARE THE COILS THAT
      MAKE THE TOUCH-TONE TONES.
   

   7. LOOK AT THE COIL ON THE LEFT WITH THE FIVE SOLDER CONTACTS FACING
      YOU.  COUNT 4 CONTACTS FROM THE LEFT AND SOLDER ONE WIRE TO
      THE FOURTH CONTACT FROM THE LEFT TO THE LEFT PLE OF THE SWITCH.
   

   8. TAKE A LOOK AT THE BOTTOM EDGE OF THE THE KEYPAD.  YOU SHOULD SEE A
      ROW OF THREE GOLD PLATED CONTACTS (TO THE RIGHT OF TWO VERY LARGE
      CAPASITORS).  GENTLY SEPERATE THE LEFTMOST CONTACT.  THEY ARE
      SOPT WELDED TOGETHER.
   

   9. SOLDER ANOTHER WIRE TO THE TOP CONTACT (THE ONE FURTHEST FROM
      YOU).  SOLDER THE OTHER END TO THE RIGHT POLE OF THE SWITCH.
  

  10. TAKE THE LAST WIRE AND SOLDER IT FROM THE OTHER CONTACT TO THE
      CENTER POLE OF THE SWITCH.
  

  11. PUT THE PHONE TOGETHER AND MAKE A HOLE IN THE CASING TO PUT THE
      SWITCH THROUGH. (YOU MAY JUST LET THE SWITCH DANGLE OUT BUT IT
      LOOKS BETTER IN THE CASING).

USING YOUR SILVER BOX:
   

   NOW, HOPEFULLY, WHEN THE SWITCH IS IN ONE POSITION, YOU WILL GET NORMAL
   TOUCH-TONE TONES, AND WHEN IT'S IN THE OTHER POSITION, IT WILL PRODUCE
   THE A,B,C,D TONES THAT MAKE UP A SILVER BOX!  THE KEYPAD ON A SILVER
   BOX GOES LIKE THIS:
                        1 2 3 A
                        4 5 6 B
                        7 8 9 C
                        * 0 # D

   I MYSELF, DO NOT KNOW MUCH ABOUT WHERE AND HOW TO USE A SILVER BOX.
   ALL I KNOW IS IT ALLOWS YOU TO ACCESS A MILITARY NETWORK, AND DOES
   SOME STRANGE THINGS TO OPERATORS AND OTHER SPECIAL CALLS.  WHEN THE
   SWITCH IS IN THE "SILVER BOX" POSITION, THE 3,6,9,# ROW WILL BE
   THE A,B,C,D ROW.  THAT'S ABOUT ALL I CAN TELL YOU.  ASK AROUND FOR
   TIPS ON SILVER BOXING.  GOOD LUCK!
