if you call your phone put the passcode in it it should prompt you to change settings

The KX-TG5621 isn't an answering machine. It will ring until you answer, some answering machine picks up, or the caller hangs up.

To change the ring count on your answering machine, refer to the documentation for that answering machine. If you require further assistance, please add a comment to this question and specify the make and model of your answering machine.

The phone is stupid. However, there could be a voice mail feature in the system the 7730 plugs into. Panasonic makes both internal and external voice mail systems that attach to the various KX-T systems.

Since the mail boxes are assigned in the voice mail system and a 7030 is a phone, I'd start with calling the voice mail system :-)

Mailbox 999 in a TVx system administers the system and allows you to add a mailbox.

The simple answer is you can force the PBX into night mode by dialing 782 on the main phone. However, it does requre programming, so if you don't have night ringing and voice mail defined, then it still won't work. 781 goes back to day mode.

Press and hold "Clear" until it beeps. It will clear the invalid voice mail msg.

Called Panasonic Support. The unit will NOT record voice messages whilst in talking mode.

Yes that is a problem I see, but to be very candid it should not be related to the battery replacement, and more from getting bumped around. Did you happen to move? Nevertheless, it is usually from an internal component failure or solder break inside the phone (unless your volume is turned down, but even at the lowest level its audible). Did you happen to use a headset? Sometimes excessive tension from the headset cable will break the receive circuit you could check the solder joints. But to be candid, it sounds as if you need to send it in for repair. You can find some options by googling ... Panasonic cordless telephone repair. The kx-tc1484b is a nice phone, good range, and normally very durable, certainly worth fixing.

My 1740 handset volume was also low. As a shot in the dark I changed the speaker and it fixed the problem. I got a new speaker from www.panasonic.com .
