Customer Question

I have a Panasonic phone system KX-TG 7871. We have tried setting the date and time several times but the phone remembers it for a few hours, or even a day or two. How can I get the phone to permanently keep the right day and time?
JA: How old is the phone?
Customer: About 10 years old.
JA: How long has this been going on? What troubleshooting have you tried?
Customer: We were away from this phone since May. When we arrived back mid Oct., we noticed the time was incorrect, so since maybe mid Oct. We just tried resetting the time and date many times.
JA: Anything else you want the electronics expert to know before I connect you?
Customer: Don't think so.

Hi, I'm Nathan.
Sorry to hear that you're having trouble with this but I'll do my best to help you.

The problem here is that the phone company has an incorrect time setting on their end, which is being automatically broadcast as a time signal along with the caller id information, causing the phone to constantly be out of sync.

To correct this, you'll need to disable the auto time set (manual mode), set the time once more, and then the setting should stick.

Grab a handset and key in Menu # 2260 (Or Menu#226, up/down to MANUAL)


Then, Menu#101 to re-enter the date and time.

Best regards,
