Today, telephone connectors of the RJ-11 type have almost replaced the old ones, for example, of the RTShK-4 type. Almost all new telephones are equipped with plugs of this standard. Use one screwdriver to plug in the appropriate type of socket.
Instructions
Step 1
Purchase an RJ-11 telephone jack. Choose its type, depending on the desired installation method on the wall and your own design preferences.
Step 2
Make a decision about how you want to connect it: as an adapter for an existing outlet of the RTShK-4 type or instead of it.
Step 3
To make an adapter, take a plug of the RTShK-4 standard. Open it and turn with the middle (plastic) pin downwards, with the screws towards you. Do not connect the outermost contacts of the socket anywhere. Connect the two middle pins of the socket to the two right pins of the plug. Close it.
Step 4
Connect your phone through such an adapter and check if it works. If not, disconnect it from the line. Open the RTShK-4 socket and see if the connection of the wires to it complies with the standard (both wires are connected to the right contacts). When doing this, do not touch live parts. If not, change the wiring in the plug accordingly. Then close both the outlet and the RTShK-4 plug. Check again if the adapter works.
Step 5
To install an RJ-11 socket instead of the existing RTShK-4, first pick up the handset on the parallel device. This will prevent the high voltage ringing signal coming in. If there is no parallel apparatus at all, work with rubber gloves. Disconnect the wires from the RTShK-4 socket, then dismantle it. Save it in case you have another unit with an old plug. Connect the wires disconnected from the RTShK-4 socket to the middle contacts of the new RJ-11 socket, and do not connect anything to the extreme ones, as in the previous case.
Step 6
If the new outlet also has a cover, close it. Connect your phone to it. Hang up the handset on the parallel machine.
Step 7
Make sure both phones (new and existing parallel) are fully functional.
