The function of a Pink Box is to add a hold button that allows music or
|
|||
|
|
anything else to be played into the telephone while the person is on hold.
|
|||
|
|
This box can either be built right in the telephone or as a seperate box.

1. Open the wall box and locate the RED and GREEN wires.
|
|||
|
|
2. Take a piece of RED wire, strip the end, and attach it to the red lead on
|
|||
|
|
the wall box. Do the same for the GREEN.
|
|||
|
|
3. Connect the GREEN wire to the ANODE end of the LED.
|
|||
|
|
4. Connect the CATHODE end of the LED to the UPPER pin of the primary side of
|
|||
|
|
the transformer (See diagram below).

|
|||
|
|
|
|||
|
|
5. Connect the pin directly across to one pole of the phono jack.
|
|||
|
|
6. Connect the RED wire to one side of resistor and to the C pole of the
|
|||
|
|
transistor.
|
|||
|
|
7. Connect the open pin of the switch the other side of the resistor and to
|
|||
|
|
the G pole of the transistor.

=
|
|||
|
|
|
|||
|
|
Hook the RED and GREEN wires up to the appropriate terminals and hook the
|
|||
|
|
RCA jack to the output on your stereo. Turn on your stereo at a good volume.
|
|||
|
|
Now call a friend. To test the Box, hold down the switcn and hang up the
|
|||
|
|
phone. The LED should go on and your friend should hear music. If nothing
|
|||
|
|
happens, start over. The hold is shut off if you pick up a phone on that line
|
|||
|
|
or your end hangs up.
