How do I earse all messages in the memory step by step!

I'd suggest installing all applications on your memory card, and moving all the files on your phone to the memory card along with all messages.

Step One - Go to Messaging (Meesag. on Main)
Step Two - Hit Up Options > Settings > Other
Step Three - Go to Memory in Use which will say "Phone Memory" and select your memory card.
Step Four - It will now ask if you want to move your messages over to the memory card (yes)
Step Five - It will ask if you want to keep your messages on the phone as a backup (no)

Acording to my experience u must download file explorer using java and then through that u can explore not only memory card but also shared folder and going inside it u can delete many unwanted that u dont require but be carefull while doing it dont delete important files and u must be knowing that when u delete meseges in ur htc they are not completely earsed they go to deleted items same as recycle bin in ur windows.

please state model of ur 4n, ths mst b simple.

try open from explorer from the left side

You don't need to erase the messages. Once you have listened to them, the next time a message is left on your machine, it will erase the older one.

Since you declined to specify the model of your Uniden DECT 6.0 system I can only suggest you select it from the list beginning here to download a copy of the manual.

The best thing to do is to clear the system memory. Aqualink can have a problem with "ghosting" Things just go on by themself when not programed to. A bad spa side remote can do that to but that is another problem.
To clear the memory
Push the menu button once
Push the back arrow to "System setup"
Push star * or enter button
Push back arrow till diplay says " clear memory "
Push star or enter
Push star or enter again to comfrim.
You will get a message "earsing memeory"
Now you can reprogram system
If you want differant run times like a summer and winter timing you can do that with the program groups

Hope this helped

try earsing all the songs to clear the memory and then put the songs back on but maybe twenty less to open up 3 mega bytes

plug your mp3 player to usb device of your keyboard.
windows should find a new drive. Opal.
click on the new drive there.
Go to my music in the opal folder.
Right click on the music you want to earse.
Go to delete and delete it.
