Hand set not turning on

Hi I recently moved and during that time me phone was not connected to an electrical out let for three four days. However when i did plug it back in the hand set wont turn on it just stays dead. i charged it without a phone jack in it for 12 hours but the headset remained dead while the charging red light on the base was on. I bought a new uniden 778 battery and installed it in the proper way aligning the color of the wires and tugging at the plug to make sure the connection was secure. I have charged the head set for 12 hours and still headset is dead. I dont know how to turn it on i pressed end and call buttons alternately for a bit to see if that wuld turn it on but nothing. so whats wrong? Help appreciated Mo

The base unit should not need a charge. It should be powered by the plug in adapter. It may have a battery to keep operation for a short time in a power outage. The adapter may be loose, the adapter could be broken or the plug in the phone may be broken.

I had the same problem!

What you need to do is hold the "end" and "#" key for 5 sec, which will deregister the headset then all you would have to do is place it back in the base for it to registered again.

Hope this is solved for you. If not, I found the connection for the battery a little temperamental and had to play with it a bit before the connection worked properly

Hi. My At&t Cordless 2 Hand set Telephone (EL52213) Answering machine (ON) doesn't record incoming messages. The Message window shows 0. The Telephone base is connected with my FAX machine (Teleph

If your Phone service is recording messages, that disconnects your line. You need to have them turn that feature off, OR set the answering machine to answer is less rings, say two or three. If the FAX machine listens to the line, it can still be set at a higher amount of rings, say four, and should still answer any FAX signal as it's sent to the answering machine.

How do we keep our Panasonic KX-T7731 from changing back to night mode? I recently reset the time and every time I do it changes to night mode. How do I permanently set my phone system on day mode?

This has about 5 different conditions, so let me start somewhere.

Pretending your 7731 is connected to a recent Panasonic KSU, like a TA series, you have the ability to set the time by hand, or CID delivered in the first call after 2 or 3 AM will do it. If the sender is still on standard time (typical with VoIP delivered CID), then it will reset the clock to a different time (-1 hour) every day and it will be noticed if you set the clock and the first call of the day follows.

In addition, via programming from the main phone, you can set manual or automatic switching for day, night, and lunch modes. That procedure is outlined in the Programming Manual for your system, but it involves setting the clock times in Maintenance console 1.4 or programs 006 and 007.

If you absolutely want to never have to deal with clocks or night mode, then set 006 to manual and dial 781# on the intercom from the main phone (x101).

Note that this is only the solution for TA series KSU's.

Recently bought uniden xdect 7055 plus two cordless & i have spent 2 hours trying to get to work but no such luck - seem i have to register my ID with telstra before they will connect me to my telstra...

The manual does not make it clear that you have to set the day/date/time option on the handpiece - not on the base unit (which you would think was the logical place).

The base unit has only three options under its menu (see page 9 of the Owner's Manual).

See pages 9 and 10 of the Owner's Manual.

Time right on phone, wrong in answering system causing it to answer during open hours. How do we change?

Dial into the voicemail and enter *#
followed by the System Administrator Mailbox number:
[#]+[0] = two-digit mailbox system
[#]+[00] = three-digit mailbox system
[#]+[000] = four-digit mailbox system

When requested, enter the System Administrator password. Default = [9]+[#]+[56].
Press [4] to set date and time
either enter:
[1] to review data - the current date and time settings in the Voice Mail are announced,
then you are returned to the Administrator Options Menu.
[2] to change data - after the first prompt, enter the time in four-digit military time format
e.g., 0930 for 9:30 a.m. or 1830 for 6:30 p.m. After the second prompt, enter the date as a
six-digit number in MMDDYY format. You are then returned to the prompt that asks if you
want to review data, change data, or exit.
Press *** to exit programming

When power connection is droped

yes it is necessary for the base station to have a permanent electrical connection. when you receive and send calls, the base station is the transmitter and receiver of all of the handsets. if your power goes out a lot, get a corded phone as a backup (available at walmart for less than 20 bucks).

Round button in middle quits working.

Sounds like you may not be selecting the right menu buttom. The soft keys are right below the screen. these three buttons function change depending on which screen you are viewing. I have copied the instructions from the manual below. You must select phonebook to view the phone book using the round button. You must select volume to change the volume with the round button.

The Standby Screen
When the phone is in standby, the handset display shows the following items:
Ringer off icon (when the ringer is off)/ day of the week and time / battery iconHandset ID and BannerNumber of new Caller ID calls received (If there are no new Caller ID messages, the Handset ID appears here.) SUN 12:00A Handset #1 New CID: 5REDIALMENU
Using the Four-way Function Key
Your handset has a four-way function key that allows you to move the cursor (or highlighted area) on the display and access the most commonly used features at the touch of a button. By moving this key to the left, you open the Phonebook. Move the key to the right to access Caller ID information. To use this four-way key, place your thumb over the key on the station and move to the four positions to get the feel of how it moves and operates.
Using the Handset Menu
To open the menu, press the MENU soft key. Highlight the option you want by pressing the four-way function key. This will move the cursor; the option currently highlighted appears in reversed out text. Select the highlighted option by pressing the OK soft key. To exit the menu and return to standby, press [].
If you do not press a key within 30 seconds, the phone will time out and exit the menu. When setting Date and Time, the time-out period is extended to two minutes.
Note: For GLOBAL SETUP and DEREGISTRATION menu options, make sure the line is not in use and the handsets are within range of the base. 123abcdefView the phonebook Four-way Function KeyUpView the Caller IDDown123abcdefView •

In Use LED flashing constantly

Your phone may have lost registration to the base. 1) Try disconnecting the power to the base and then re-connecting the power with the cordless phone in the base. Give it a few seconds, then see if it works. 2) Try removing the battery, wait 10 seconds, re-install the battery and set the phone in the charger.
