How can connect to handset please? when I buy the phone have 2 handset,but no book basic setup..model DXI5686-2

The procedures to deregister are, of course, specific
to each make and model number of cordless phone.
All of them are a LOT more involved than simply
removing the battery.

For some AT&T, VTech, Uniden, & GE model numbers
you might try the following:
=====================================
For many AT&T models it is simple:
1. When the handset says "Connecting..."
enter *331734 [menu]
it will soon (chirp) and display "Not registered"
=====================================
For many VTech models it is a bit more involved:
1. Start by taking off the battery compartment cover.
2. press [menu]
3. scroll up/down to "Settings"
4. enter * 7 8 9 0 #
5. if display reads "Test Base",
scroll to "Test Handset", press [select]
scroll to "next page", press [select]
6. scroll to "Register Clear?", press [select]
7. display asks "Confirm?" or "Register Clear??",
press [select]
8. display reads "Ok" (chirps), press [ off ]

9. UNPLUG THE HANDSET BATTERY
(this is why the cover is off)
10. Wait ~30 seconds, re-connect the battery &
replace the cover
11. display reads "Not Registered"
=====================================
For many Uniden models:
1. Press and hold the [END] and [ # ] keys at the
same time, after a few seconds the display reads
2. "System Reset, Deregister Handset"
3. scroll to "... Base Unavailable"
press [SELECT]
4. Handset (chirps)
press [END]
5. display reads "Not Registered, Place in base..." =====================================
For some GE models:
1. press "program[mute]"
2. scroll to "Handset Setup" press "program[mute]"
3. scroll to "Deregistration" press "program[mute]"
4. scroll to "Yes" press "program[mute]"
5. display reads "Not Registered"

=====================================
Once you have the handset displaying "Not Registered"
you can follow the User's Manual instructions to register
the handset.

The model number for your cordless phone is shown on
a small sticker underneath the battery in the handset --
enter this number at www.manualslib.com to get a free

Good luck!

try to check the telephone wire connections. or try to use the other phone box to test.

Yes, buy the correct one and follow the instructions in the manual. We are unable to give advice when you won't say the make and model of your base station or the (Different make) handset. I mean, does your new handset even have an address book function? Does your base station have an address book function?

nokia3110 is a basic model if any problem occurs in application
there you need to update your handset.
This is because there no any software available for this basic handset.
So please visit the nearest nokiacare and get your handset FLASHED.

Yes you can use your handset as a modem infact most modern handsets are able to be used as a modem , but before you attempt to connect please chack with your network operator as  charges may apply depending on the network you are using.

There are a number of ways to do this but to start off with you need to make sure that the handset itself can actually access the internet
Settings can be obtained from your network.
Once you have checked the above with your network provider then the most simple way to connect is by USB. firstly we need to check that your phone is correctly setup

Using the USB cable and sony erricson PC suite software included firstly install the software then connect the USB cable to PC and phone.
