Question about Sony IT M11 Corded Phone

Open Question

Sony corded phone IT-B4 wont work!

This beautiful phone worked perfectly for years and then i put it away and used another for a few years. i want to use it now and though its had no knocks or water etc it simply will not give a dial tone or work. i have taken the base panel off and the wiring and board inside looks in perfect order.

i note however that there is a lithium cell in it type CR 2032 which is hard wired into it. i am wondering if this could be "dead" or otherwise be the problem. any ideas gratefullly received. and thanks in advance.

SOURCE: Replaced battery in handset. Got a dial tone and all was well. Picked up handset later in the day and it was dead. Unplugged and reattached everything - no luck.

Try taking batteries out, but also unplug base station. The aim is to disperse all power in the phone so that it resets itself. I would leave everything unplugged for 24 hours and then reassemble and see if the problem has gone. Its worked for me loads of times with different electrical appliances. Hope that helps.

SOURCE: problem with my handset identifying base phone

I can help you register the handset if it is functional. I am a former Sony Tech.

Hand lotion gets on the keypad and into the back of the rubber keypad. There is a conductive carbon on the back of the keypad to short the circuit board when you press the key. Oil makes it stop working.

Parts are no longer avaliable but you can glue a small piece of alumimum foil on the rubber.

For Register Handset Error email me I will walk you through the steps.

SOURCE: cannot use with another phone on the line

This sounds like a polarity issue in the new home.
I think you hace red and greed reversed somewhere in the telephone wiring. All greens should go together as all reds. If it is newer wiring the colors will be different, but the same rules apply. example: blue/white and white/blue striped wires will be one pair, it is easy to get then reversed if you are not careful.
Another possibility is there could be two incoming phone lines that are crossed with the red (or blue white) paired with the green (or white blue) from another incoming line.
The 2nd line should be on the black/green (orange/white pair)

Panasonic proprietary phones need a 4 wire line cord. Most phones work with a 2 wire or 4 wire line cord because they use the center two conductors, but panasonic proprietary phones use the outside two conductors of a 4 wire line cord.

The 52860 is a phone line powered phone. There may be a memory backup battery or capacitor but it should not effect the operation of the phone drawing dial tone. Perhaps the hookswitch contacts are oxidized from storage and using it is cleaning them up a bit. If there is a battery, it should be accessible from either the bottom of the phone or, more typically, from under the directory card on the base.

Panasonic phone KX-TG4500 base not turning on, I have had it for 3 years and all of a sudden it died, like a battery goes off.


I could tell the base unit was about to go a few days ago. Have had the phone for years with intermittent problems but it has been for quite awhile now. However, the screen on the unit started to blink a bit a few days ago. Had a feeling it was about to go but the phone kept working until this morning when it suddenly dies. After reading that changeing the cord might work, I replace the unit power cord with one from my handset and the phone is working again! Thanks for the suggestion!

Wow, that's a great record for any cordless phone! The battery probably only needs to be replaced. The battery can no longer hold a charge.

DKT's wont ring from transfer


put an "H" after the extension in the voicemail, i.e. 200H, you have to put in your #656 #657 codes into the phones to integrate the voicemail. #656 91, ext of voicemail pilot, hold #657 92, ext of voicemail pilot, speed dial button (program one on the phone if it doesnt already have it), enter the number of seconds before the phone should forward to voicemail, i generally do 16, hold. that should fix that!

Phone wont work


Check the cord by using another phone. If it's good and your phone still won't work or show ANY signs of life, then i'm afraid it may be dead. Hard to say from here.

Hope this helps.
