Phnoe and Answering System Inoperative - E1 flashing

We came home and found our Panasonic KX-TG2357 unit inoperative. There were about six lights flashing and the display said E1. The handsets don't work, and the answering machine doesn't either. Our third phone, directly hooked to the phone cable and not to the answering machine, does work (and yes, we've had this setup for years - ever since we bought the Panasonic, and have had no probloems).

Of course, the manual doesn't talk about E1 and what to do about it.

I unplugged the AC adapter and plugged it back in. I disconnected the cordi nto the base unit and reconnected it. I unplugged the phone cable from the wall and plugged it back in. None of these intuitive things worked.

Any suggestions? Surely you have solved this problem before!

Thanks -- Randy Seaver (

Re: Phnoe and Answering System Inoperative - E1 flashing

I have KX-TG2357 unit. Yesterday I had disconnected the
instrument as there was a function and we wanted space.
After the function I again connected the unit and plugged in.
The red light for charging is not seen. I am also not aware
whether the intstrument is getting charged or not. Kindly let
me know what to do.- as venkatachalam

I read about this, and while you were gone, if your power went out, try unplugging the batteries from the back of both phones for a few minutes & put them back in..I hope this helps!

Answering system

It first sounds as if the handset isn't charged properly. Check the battery status first. The manufacture advises to charge the system for approx. 7 hours before any use occurs. Second, make sure that the registration took, when programming the phone originally. I would de-register the handset by: 1 {MENU} i {0}{0}{2} 2 {3}{3}{5} i {OK} 3 Select the handset you want to cancel by pressing the desired handset number ({1} ? {4}). Then re-register by: 1 Handset: {MENU} i {0}{0}{1} 2 Base unit: KX-TG6021/KX-TG6022/ KX-TG6023 Press and hold {LOCATOR} until the IN USE indicator flashes. KX-TG6051/KX-TG6052/ KX-TG6053/KX-TG6054 Press and hold {LOCATOR/ INTERCOM} until the IN USE indicator flashes. LAfter the IN USE indicator starts flashing, the rest of the procedure must be completed within 1 minute. 3 Handset: Press {OK}, then wait until a beep sounds. 4 {OFF} Third, make sure that the display on the handset does not show "SP-Phone" in the display, if it does press the phone icon button. Fourth, Do you currently have voicemail from your phone service provider? If so, the answering machine will not answer. Make sure that the answering machine portion is turned on. Do this by: Press {ANSWER ON} to turn on/off the answering system. When the answering system is turned on, the ANSWER ON indicator lights. When the answering system is turned off, the ANSWER ON indicator turns off. If there are any further questions or comments, please post here. Please rate this solution through fix-it. Thank you
