Adding speed dial nos to uniden waterproof handset

From your handset, you just have to press the mute button, your phone should start telling you the time, date, ect. press the #5 key and then the #8 key and start recording your message. When finished press the # 8 key again. Hope this helps

This phone uses inductive charging because of the waterproof feature. I suggest that you remove the
battery cover from the back of the handset, unplug
the battery, and then plug it back into the handset.
This solution worked for me.

On the base, open the menu and select Register Handset. The display should say Handset Registering.
On the handset you want to register, press and hold # until the handset display says Handset Registering (about 2 seconds).

I had the same problem as long as they are plugged in correctly and you put the #2 handset into the #1 cradle to register it to your base then try hanging the phone up several times. These are expandable phones so that I believe you can keep adding other handsets. So sometimes they think you have a few more handsets than you really have so when you hang up it may not know what handset you are hanging up #1 #2 or #3 #4 etc. So I had to keep hanging them up until it finally hung up. Then I had to re install them so it knew I only had 2 hand sets. So then you start from the beginning, like when you took it from the packaging. I hate these phones. I ended up replacing them with different ones. Plus I always keep a rotery phone laying around put away because during a power outage you still can plug in an old dial phone and it will work! Nothing like old technology.

Not sure if you still have this problem, but...

Basically go on you base unit, and hit "MENU/SELECT". Scroll down to "REGISTER HANDSET" and click "MENU/SELECT". On your waterproof handset, hold the "#" key until it displays "REGISTERING HANDSET". And voila! After that finishes, your waterproof handset will be good to go!

It may not be registed with the main unit. You may need to register the handset. With my uniden all i have to do is put it in the main base until it says what handset it is (it should be a number).

If you have any questions please dont hesitate to ask

Press and hold a number key (0-9) associated with the speed dial until the phone number appears, and then press talk/flash or speaker on the handset or speaker on the base. The number stored in the speed dial is dialed.

When the phone is not in use, press and hold the number key (0-9) that is assigned to the phonebook entry. Press flash on the handset to dial the number.
