Hi Amy,

I have two of these phones. The feature set is really good. The only thing missing is a "Voice Mail" indicator light. You have to pick up the line and listen for the intermittent dial tone.

The other problem is that they are not very reliable. Both of my originals developed problems with the answering machine portion, but were replaced under warranty. Have had issues with one of the replacements also and now use it with an external two-line answering machine.

Regarding your problem, there are a few possibilities. Not all phone cords are created equal. The cord that goes from the wall to the phone uses a plug/jack called RJ-11. An RJ-11 connector has room for four contacts. The contacts themselves are just gold-plated wires.

Take a very close look at all of the cords you are using, as there are two different types that look nearly identical. A single line cord will only have two wires inside, and the RJ-11 connector will only have the two center pins filled with the gold contacts. A two-line cord has four wires and the RJ-11 connectors will have four gold contacts at each end.

Once you are sure that your cords are all two-line (four gold contacts on the RJ-11 connectors), the next thing is to understand how two different lines are put into one cord.

The first (main) line will occupy the two center contacts. To add a second line, they need to connect to the two outer contacts. It may be that you need to re-wire the wall jack on one of the lines.

If they are both wired to the two center contacts, the splitter cannot do its job. The way to tell this is to make sure that each wall receptacle will give a dial tone when plugged into a single line telephone. If that is the case you will need to re-wire one of the wall outlets.

You would need to remove the wires from the center two slots on one line and insert them into the outer two slots. Take a look at what you have with regards to cords and the results of your tests with a single line phone. If you need to rewire a wall outlet, I can walk you through that.

Testimonial: "I bought another jack(4wire) to rewire the second line. My incoming wire colors from Telco are green, red, yellow, black. I don't have a lot of slack in the line. I have tried yellow and black to yellow and black. AND blue to yellow and white to black. Neither worked."

    Your help would be greatly appreciated if you could tell me which wires need to go where.

    Good job, Amy! Persistence pays off. As you have found, the red and green are for line 1 and go to the middle two pins of the RJ-11, while the yellow and black are for line 2 and go to the outer two pins of the RJ-11.

    In the old days of rotary phones, the polarity (interchanging red and green OR yellow and black) made a difference. Not any more. Glad things are working for you now.

How to connect a philips antenna to a trutech tv

Unplug your television and turn the set around so the back of the set is facing you.

  • 2 Disconnect the antenna or cable connection from the television's "VHF," "Antenna In" or similarly worded port if it is connected.
  • 3 Examine your splitter and notice one end of the device has a coaxial port while the other end has two coaxial ports.
  • 4 Plug the coaxial end of the television antenna into one of the two coaxial ports on the splitter.
  • 5 Plug the coaxial cable coming from the cable television connection outlet into the second coaxial port on the splitter. Use the port next to the one you used to plug the television antenna into.
  • 6 Place one end of a 2 foot piece of coaxial cable into the single coaxial port on the splitter.
  • 7 Plug the other end of the 2 foot piece of coaxial cable into your television's "VHF," "Antenna In" or similarly worded port.
  • 8 Plug in the television set and turn it around so the screen is facing you.
  • 9 Use your television's remote control to access the "Menu," "Setup" or similarly worded function. Or press the "Menu" or "Setup" button on the front of the television.
  • 10 Select the "Channel Setup" or similarly worded function. Set the Input to "Cable" and perform an "Auto Scan" to locate all available cable television channels.
  • 11 Select the "Channel Setup" or similarly worded function, then set the input to "Antenna" and perform an "Auto Scan" to locate all available broadcast channels. Your television will locate both broadcast and cable television channels.
  • 12 Scan the channels on your television to make sure all available channels have been found. If you are missing any channels that you know you should have, manually program the channels into your television using the "Channel Setup," "Manual Channel Setup" or similarly worded function.

    Fax gets a phone line error. I switched from 1 line to another. I used a single line splitter but it still will not fax. What to do?

    Hi, it seems you got a connection problem. Here are some tips to check it:
    1. Make sure the phone line in the wall is working. There should be a dial tone if you connect a regular phone device in that.
    2. Check if the telephone cable that you're using is in good condition.
    3. Telephone cable from the wall/splitter must be plugged in to the Line port behind the printer.
    4. Make sure that it's the correct fax number assigned in the printer.
    5. If all is ok but still having the error, try plugging the printer/fax straight to the wall jack bypassing the splitter.
    Hope this helps.

    My dish 322 receiver wont work 2 tv,to get service

    • There are two satellite inputs on the back of a 322. There may be a single cable going to a splitter connected to these two ports or two individual cables.
    • If there are two cables swap them, if you still get signal on the same input only then the receivers input is dead.Otherwise follow the bad cable and ensure it is not damaged or disconnected. Swap the location on the other end and see if the issue stays on the same cable. If so replace the cable, if not replace the LNB or Switch.
    • If there is a splitter bypass it and connect the single cable directly to the input that does not work. If there is no signal the port is bad, replace the receiver. If there is signal then reconnect the splitter, press menu 6-1-1, check switch, and then test. Allow the test to finish. If the two inputs do not match replace the splitter...

    The 2 jacks on the back of the Arris modem are labeled "1/2" & "2". The first jack labeled "1/2" means that the jack is capable supporting 2 different phone numbers, a line 1 and a line 2. The second jack labeled "2" means that it is capable of supporting only a second phone number. Therefore your 1 phone number is working correctly from the port labeled "1/2".

    There are different types of phone splitters. It is possible that the one you used may have been to split lines 1 & 2 on a single jack into two seperate jacks. Take a closer look at the splitter and see if the 2 ports are labeled differently.

    Hope that helps.

    No dial tone, just buzzing noise - should be 2 line phone, 1 jack

    What you need is a dsl filter since you are working off a splitter. You can usually get these for free from your phone company.

    Telephone line connection

    Two options:

    1) Pick up a phone line splitter (Radio Shack or just about any other retailer has them) that has a plug on one side and two jacks on the other. Plug this into the phone jack where the line to your computer is connected. Plug the cord to the computer back into one jack on the splitter and plug the line to the fax machine into the other jack. (If it will physically fit into the space on the back of the computer, you can just plug the splitter into the modem connector, plug the line cord into one jack and the fax cord into the other.)

    2) (Useful if the phone jack is behind furniture or just hard to get at.) Get a phone line splitter with all jacks (two on one side, on on the other). Unplug the line cord from the computer and plug it into the single jack on one side of the splitter. Then run a new line cord from one of the two jacks on the other side back to your computer. Plug the cord to the fax machine into the other jack.

    Both lines ring for one call

    the splitter is on the one phone line through the single phone jack so it is logical that that is where the problem is
    if you have 2 phone lines( 2 lines in from the service provider connection point on the building then there is no need for a splitter as in effect you have two phones
    a machine cannot distinguish which phone to work from the one inlet line so it rings all phones connected
    a splitter is only used when you run a phone and another unit such as a computer off the same line and not as how you have it set up
