Standby mode is when the phone is not on a call, you're not dialing one, and you're not doing anything with the menus. It's standing by, waiting for you to call or for someone to call you.

NEXXTECHâ„¢ BIG BUTTON CALLER ID# SPEAKERPHONE\r\n message waiting indicator will not turn on.took phone back they gave us a new one and it still doesnt work. We subscribe to call answer thru the phone...


Message waiting is sent to subcribers in 3 ways; by a method called FSK, by "stutter" dial tone, or by voltage. Since you're the one looking at the model number and/or the manual, you need to find out which one you telephone company is sending and buy the appropriate equipment.

Since you've tried two phone, I'm guessing that it is just not compatible with what your telco is sending.

Please follow these troubleshooting steps;

Tip 1 of 9
Move the handset closer to the base. The operating range may vary with environmental conditions and time of use. There may be places within your environment that a cordless phone will not work well. If the problem only occurs in certain areas of your environment, you can conclude that there is nothing wrong with the phone. Consider trying a phone that operates on a different wireless frequency.



Tip 2 of 9
If you subscribe to DSL service for this telephone line, DSL filters must be plugged into EVERY phone jack that has a phone. The DSL signal can cause static/noise, squealing (similar to fax tones), caller ID disruption and other issues on your line. DSL filters block the high frequency DSL signals from being transmitted to the telephone. If you are not using the DSL filters provided by the telephone company, this will cause static/noise and possibly caller id issues on your phones.
In most cases, we recommend you connect the plug end of the DSL filter into the telephone jack, then connect a telephone cord between the filter and your phone.
Please contact your service provider to obtain DSL filters and installation information.



Tip 3 of 9
Other electronic products (i.e., 802.11 wireless networking products, radios, radio towers, pager towers, cell phones, intercoms, room monitors, televisions, personal computers, kitchen appliances and other cordless phones) can cause interference with your cordless phone. Try installing your phone as far away as possible from these types of electronic devices.


Tip 4 of 9
To get better reception, try moving the telephone base to higher location. Relocate telephone base near a window if using telephone outside.



Tip 5 of 9
Excessive background noise will cause a speakerphone to fade in and out. Try controlling the background noise by turning off any audio devices near the speakerphone. Also, try to avoid interrupting the person at the other end of the conversation while they are speaking. If background noise cannot be controlled, you should terminate speakerphone operation and return to normal handset mode.



Tip 6 of 9
Disconnect any other equipment that is connected in series with your phone. If you phone begins to perform normally, there is a compatability issue with your other equipment.



Tip 7 of 9
If your phone shares a power outlet with a modem, or if it is plugged in to a shared surge protector, try plugging the phone (or modem/surge protector) in at a different location. If this solves the problem, re-locate your phone or modem farther apart from one another, or use separate surge protectors.



Tip 8 of 9
There may be places within your environment that a cordless phone will not work well. If the problem only occurs in certain areas of your environment, there is nothing wrong with the phone. This is normal radio operation.



Tip 9 of 9
You may have a line problem. To test for a line problem, test your unit at another location such as your neighbor’s or relative’s house. If your unit works at another location, contact your local telephone company
