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
