My telephone is displaying "Check Tel line"

Check Tel Line means that the phone is not getting a dial tone. Unless you connect the KX-TGD560 base to a RJ-11 phone cord going to a RJ-11 jack with a working telephone service, this message will continue.

I've never used the cell phone link without having a land line connection. The Link-to-cell option for using the handset on Cell 1 (or Cell 2) may still work. You need to have a compatible cell phone close to the base. The phone needs to be positioned where it gets good signal strength. Test this yourself.

I hope this helps.

(Panasonic has the manuals and a trouble-shooting guide for the KX-TGD560 here: http://eng-ca.faq.panasonic.com/app/answers/detail/a_id/55826/~/product-guide---telephone---cordless---model-kx-tgd560%2C-kx-tgd562%2C-kx-tgd563%2C . )

Your phone line is dead or the cable came out of the wall jack.

Do you mean the KX-TGF370 series phones? Panasonic doesn't have a KT-TGF370 to my knowledge.

To remove a single number from the Call Block list, press Call Block on the handset (below 0) or Menu # 2 1 7 at the base. This gets you to the Call Block sub-menu. Choose the line for Block a single number with the up/down arrows and press Select. Navigate with the up/down arrows through the list to the specific number that you want to remove from the list. Press the soft-key for Erase. Use the up/down arrows to highlight Yes and then press Save. If done, press Off or Exit.

To remove a group of numbers, again press Call Block or Menu # 2 1 7 depending on whether you use the handset or the base. Highlight the line for Block a range of numbers and press Select. On the handset, press Menu and highlight Erase All. Press Select and then highlight Yes and press Select. Highlight Yes and press Select again. Press Off to end.
On the base, you press the soft key for Erase. Highlight Yes and press Select. Highlight Yes and press Select a second time to confirm clearing the memory of all blocked numbers. Then press Exit.

See page 34 of the manual for these details. The manual is available from Panasonic here: ftp://ftp.panasonic.com/telephone/om/kx-tgf372_en_om_.pdf .

I hope this helps.

These phones are digital proprietary telephones which means that they only work on panasonic telephone systems and not on normal analog lines. If you have a panasonic system the correct way is to plug the line into the " To Main Unit ", the handset into " Handset/Headset" and a normal analog phone into " To Tel ". If the wiring on the line jack was not done digitally the phone will also not work

KX-T7730 Phone must be connected with a 4wire line cord. you may be tested it with a 2 wire line connector.because other normal phones only needed 2wire line cords.Just connect a new 4w cord to under socket located to main unit & other end connect directly to the tel;system & see is the phone confirmed OK.
& let me know .Good luck.

You can remove your telephone line from the base unit and fix it to stranded telephone unit and hear the dial tone.If it heard then some inductor or else part may be broken inside the base unit due high current surge.If the dial tone didn't heard from the other phone also check for the corroded line cord or modular box fault with the tel line.There should be 30 Volt-50Volt D.C.Voltage at your wire ends.

Hi, you can find a free download here...
http://www.panasonic.co.uk/html/en_GB/Support/Downloads/220239/index.html#anker_220239
Just type in your model number and it will bring up a link to download 'operating instructions' or a 'quick guide'.
Hope that helps?

Contact your telephone company if you want it permanently corrected, or if you would, like dial *67 then your phone number.

I believe the problem is not the handset phone but the telephone line because the phones were working for a brief period again last night. As I said, ATT is supposed to send a repair man out today to check the lines. If the repair man says the problem is not the telephone line, I may contact you again. Thanks/
