HandsetS #2 and #3 work properly. Handset #1 has a display screen with correct datet and time -- but no dial tone, How can I fix this?

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.

The handset is fubar.

All of the handsets appear to have lost their
registration to the base and will need to
be first de-registered then re-registered.
It may be necessary to do this in three stages.
First be sure that all of the handset batteries
are fully charged.
1.
Clear one of the handsets of its registration:
hold down both the [END] and [#] keys
at the same time until the display shows the
SYSTEM RESET menu.
Since the handset is not recognized by its
base, select "Base Not Available".
Confirm the choice by selecting "Yes".
This handset will now display
"Handset Not Registered"
--
2.
With "...Not Registered" displayed, place
the handset into the base unit cradle.
The handset should now dieplay
"Handset Registering"
After ~30 seconds the display should show
"Registration Complete" and will have a
handset unit number.
If the unit shows "Handset 1" (doubtful)
then just repeat steps 1 & 2 above for each
additional handset in turn. This can also be
the route if you do not care what the numbers
are and do not exceed the maximum count
for your system ( some are 4, 5, or even 12 ).
If the handset is a number other than 1 you
may want to clear the base & re-register
all of the handsets:
3.
Using the now-registered and working handset
(number x), press both the [END] and [#] keys at the same time until the display shows the
SYSTEM RESET menu.
This time, choose "Deregister HS" and the
System Reset Menu will prompt you to
select from the list of registered handsets
which one you want to deregister: choose
one that is NOT the one you have working.
Cycle around deleting them all until only the
one that is working is left: select that one and
the system will be ready to start re-registering
all handsets again from Handset #1.
Start at process (1) above, then (2).
Good Luck!!
===============================

I had this happen suddenly on 2 out of 3 handsets with a DS6151 base and DS6101 handsets. Well, what happened is there was no dial tone on either of the 2 handsets on either of the 2 lines and a message appeared on the display "Unable to Call Try Again" after some delay, if Line1 or Line2 button was pressed.

Oddly, the 2 that did not work were the ones normally on "extension" chargers and the 1 that did work was the one on the base unit. That caused me to suspect the base unit .. which it still may have been but the solution was NOT. And, also odd, the handsets seemed to still be synched with the base unit in many respects.

Cycling the power on the base unit did nothing.
These are fairly new units and battery life is generally much longer in my experience.

The Solution:
- Remove the battery from the handset that doesn't work properly.
- Re-install the same battery.
Whatever was wrong, this reset it and the handsets started working again.
Easy fix.

Reset the hand sets that are out of range by doing the following:

1) Press and hold END and # for at least five seconds.
2) Move the cursor to select Base Unavailable and then press Menu/Select.
3) Select the base which you want to de-register from, and then press Menu/Select. Base Unavailable appears.
4) Move the cursor to select Yes, and then press Menu/Select. You hear a confirmation tone,

(For DCX150 handsets)
5) Place the handset in the base cradle for about thirty seconds. Handset Registering will appear in the LCD.
6) When the handset has registered to the base, the LCD will display Registration complete then show the handset
ID number.
If the display shows Registration failed, repeat the process again.

(For DCX200 or DCX300 handsets)
5)Disconnect the base AC adapter. Then press and hold find while you reconnect the adapter. Keep holding
find until the charge LED starts to blink.
6)When charged, registered handsets display a handset ID number. Handsets that have not been registered display:
7) On the handset, press and hold # until the handset beeps and displays Handset Registering.
8) When the handset has registered to the base, the LCD will display Registration complete then show the handset
ID number.
If the display shows Registration failed, repeat the process again.



User Manual Available Here

If “No link to base. Move closer to base, try again.” is displayed
even when using the handset near the base unit, the handset may have lost communication with the base unit. You need to re-register the handset to the base unit.
• Make sure the base unit is not being used.
• Have both handsets and base unit nearby during registration.
• Follow steps 1–3 listed below. You have about 1 minute to complete them.
• Confirm the extension number of the handset which has lost the communication by placing the handset on the base unit or charger.
If you re-register the handset using the other handset’s extension number, the other handset will not function.
• If the handset beeps 3 times and “Error!!” is displayed, an error occurred. Try again from step 1.
• You can stop registration by pressing [OFF] on the handset, and pressing [LOCATOR/INTERCOM] on the base unit.

1 Base unit: Press and hold [LOCATOR/INTERCOM] until a beep sounds.
• The CHARGE indicator flashes.

2 Base unit: Press the extension number [1] (handset symbol 1 ) or [2] (handset symbol 2) of the
handset which has lost the communication.

3 Handset: Press and hold [FLASH/CALL WAIT] until “Handset Registering” is displayed.
• When registration is complete, a beep sounds from the handset and the display shows the number.
• Wait for 20 seconds after registration is complete while the handset establishes communication with the base unit.


• If the handset beeps 3 times and “Error!!” is displayed, an error occurred. Try again from step 1.
• You can stop registration by pressing [OFF] on the handset, and pressing [LOCATOR/INTERCOM] on the base unit.

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.

Here's is the fix, I just had the same problem.

I have 2 handsets here and just had replaced in 1 of the handsets.

Here's the trick, make sure the correct handset is in the correct base. The way this is done is when one of the handsets are in their bases, they will show either HS1 or HS2 in the upper right hand part of the display.

When they are in the correct base, then go push the Find HS button on the main base and you will hear the page feature paging the other base.

When the 2nd handset starts beeping just push the Find HS button again and other handset should work.

After that it don't matter which handset is in which base.

Let me know if this works for you.

Thanks,
Brian

After waiting for over 24 hrs for an answer from FixYa and then they wanted $10.00 and trying to fix it myself, I gave up. Threw all that c$$p into a box, took it back to the store and got my money back. It just wasn't worth the time and aggravation.

hi just want to help others as desciption aint complete above

Registering a BT Freestyle 2200 handset
1. If there is a handset in the base remove it whilst you are registering the new handset.
2. Press and hold the PAGE button on the base for about 10 seconds until you hear a beep and the In Use light starts flashing.
3. On the handset to be registered, press and hold redial & CALLSd buttons together until display shows 65-.
4. Enter the base number. If this is a new handset then the base number is 1, the display shows 65-1 then PIN. which is normally 0000
5. Enter and registration starts. When the handset beeps and returns to standby registration is complete.
