Question about Uniden DMX778 Cordless Phone
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

Tips for a great answer:
To set up your clock simply install one fresh AA, LR6 ALKALINE battery. Due to the nature of long wave radio signals it is normally not possible to receive a signal during the day so it is best to install the battery late in the evening. Select your time zone by pressing one of the four time zone buttons PT-Pacific Time, MT-Mountain Time, CT-Central Time, ET-Eastern Time. The time zone buttons may be pressed any time after installing the batteries. If multiple buttons are pressed the clock will set to the time zone selected last. If no time zone is selected the clock will default to Pacific Time. Another time zone can be selected during or after the clock has set itself. Your clock can only set itself to one of the four time zones stated above. For time zones outside of PT, MT, CT or ET you must manually set the time using the Manual Time set button on the back of the movement.
When the battery is installed the second hand will advance eight seconds (two seconds per step x four steps). The clock is now searching for a signal. For the initial setting it is recommended to stand the clock in an upright position near a window. Within five minutes the clock will either receive the WWVB signal and set itself to the exact time, or it will determine that the signal is not receivable at its current location and time of day. If a signal is not receivable it will fast-forward the hands to the 4, 8, or 12 o'clock position and search for WWVB each
hour until a signal is received. If the time is manually set the clock will continue to periodically search for a signal and automatically reset the hands when the signal is received.
Select a location to place your radio controlled clock where it will be at least six feet away from a TV, computer, air conditioner or other household electrical appliances. The optimal location is near a window. Windows facing Colorado providing the best signal. The WWVB time signal will easily penetrate Masonry and wood framed buildings. WWVB will penetrate almost every residential building and most steel buildings if they have adequate windows. It is not possible, however, for WWVB to penetrate most indoor shopping malls and rooms in the center of large office buildings that do not have windows. In buildings that WWVB cannot penetrate you may set the time using the manual time set button. When the clock is exposed to the WWVB signal it will automatically set the hands to the exact time.
