When i answer a call somtimes it activates Handset sign & can talk only using the handset. It can be answered normally other times.

Suggest you reset handset and register again with base.

Instructions from manual...
Resetting Handsets If you have trouble with a handset or if you want to replace one, clear the registration information from the base and the handset: 1. Press & hold END and # at the same time until you see the System Reset menu. 2.If you still have the base the handset is registered to, select Deregister HS, then select the handset you want to reset. If you don't have that base anymore, select Base Unavailable. 3. To confirm, select Yes. The handset displays Handset not registered. Registering Handsets If you see a "not registered" message on a handset, you must register it to a base before using it. 1. Place the handset in the base; the display should say Handset Registering. 2.Wait until the display says Registration Complete (about 30 seconds), then pick up the handset and press TALK/FLASH. 3.If you don't hear a dial tone or the display says Registration Failed, charge the battery completely, then try again.

To Page another phone to initiate intercom:-

From the base station - press Find hs/Intercom.
From a handset - Press Intercom/clear.

Then select the station you want to talk with or All to
page all stations at the same time.

To answer a page:-

There needs to be an additional instruction. I am having the same problem. From standby mode, I press Intercom, the screen says "Please wait" for 2-3 seconds, then I choose a handset. Nothing happens. The user guide doesn't have any additional instructions after this point. I don't hear any paging or anything other than silence on any handset.

Hi,

When you get your samsung handset you set up mobile tracker entering two numbers of your friends or family etc. Once activated, if someone stolen your handset & puts their Sim card into your phone, your phone automatically sends the two numbers a message giving the persons cell number ( who have stolen your handset) and your phone IMEI number.

Thanks...!!

Here is the answer! Press the INTERCOM button one time.
The INTERCOM display will show on the screen.
Use the UP or DOWN arrow button to select the HANDSET number.
Press the MENU/SELECT button to ring the HANDSET selected.
Press the END button when done talking

You can't transfer calls from one handset to another. With both handsets in your posession, you could simply give someone the other one to talk so you could engage in a 3-way conversation. It would also be good to call your local phone provider to get three way calling (a small expense). I use this all the time so I can talk to two other friends at once and we can all make plans together, without having to call, hang up, call the other one, hang up..you get the drill..

Unfortunately that is the untold story about cordless phones they only have the capability of 1 open line be it the handset or or the base. There are some very pricey multi line systems, I have the same system bought two extra handsets and found out too late that I can only use them one at a time! Sorry probably not the answer you were looking for but thats the reality...

Owner's Manual, page 19, explains that only one handset can be used for incoming calls. So if you are upstairs with a handset and someone answers the other handset downstairs, your call will be cancelled if you attempt to use your upstairs handset. Very inconvenient and have returned and exchanged for another brand.

Registering Handsets to the Base
Whichever handset you choose to charge in the base is automatically
registered to the base. Any additional handsets must also be registered to
the base before you can use them.
Be sure both handsets are fully charged.
One at a time, place each handset in the base. The charge/in use LED on
the base begins to flash, indicating the base is registering the handset.
Wait for at least five seconds, then pick up the handset and press
[talk/flash]. If the display shows TALK, the handset is registered. If not,
place the handset in the base to try again.
Press [end] and continue with the next handset.
Note:
Once both handsets are registered, it doesn’t matter which
handset is placed in the base or the charger.
When you charge the handsets, Caller
ID summary screen and the name of
the handset appears.
