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

The phone should pick up the time automatically from the caller id signal, but does not always update properly.

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.

If you have any other questions, just let me know. Otherwise, please take a moment to rate my service as this is the only way I am credited for my time. Hopefully I have earned 5 Stars but if not please let me know what I can do to ensure you are satisfied. I also invite you to contact me directly with any future support needs at and ask for Nathan.

Thank you, ***** ***** a nice day,

It is imperative that you reply back to me here, on your original question only, please.

Posting new/duplicate questions costs you more and hinders my ability to reply.

Please reply back here on this page when ready.

I really need to speak to someone on the phone about this problem.
Expert:  Nathan replied 10 months ago.

I’ve attempted to accept your call request, but it appears to have failed on your end due to a payment issue. You may need to increase your deposit or clear a security hold on your account. I’ll resend a new phone offer from my end that may be more readily processed. If you prefer to continue here in chat, that is fine too. Just let me know either way.

I did send you detailed instructions above,

to set the date/time all you have to do is key in Menu#101 on the handset, enter the date, and time.

I'm happy to call you as well, if you'll accept the phone call offer I just sent.
