How do i register a doro handset with a BT Synergy 310s system

Assuming you do not have 5 handsets already, make sure that the new handset is fully charged. Carry it over to the base and press Find on the base unit. (This sends out a signal to the handset.) On the handset, press Menu and use the Up arrow to go to the line marked Settings. Press Menu to access this sub-menu. The line H/Settings should be highlighted. If it isn't highlighted, use the Up/Down arrows to navigate to this line. Press Menu to access this menu. Use the Up/Down arrows to navigate to the line Register. Press Menu again. Use the Up/Down arrows to select the base to which you want the handset to be registered. Press Menu again to confirm that base registration. Enter the system PIN for this base; the initial PIN is mentioned in the manual on page 35 and on page 54. Wait for the handset to indicate that it has been registered; it will say Registering until the process is finished. If you take too long to do the steps at the handset, the signal will stop and you will need to start over.

If you already have 5 handsets, you will need to de-register one of them. If the registration process does not properly occur and the issue wasn't taking too long, either the base or the handset is not communicating properly. If other handsets work, I'd suspect that the new handset is faulty.

BT Systems has the manual on the Freestyle 750 product site: http://btbusiness.custhelp.com/app/answers/detail/a_id/12103/~/bt-freestyle-750-user-guide . The direct link to the manual is http://btbusiness.custhelp.com/ci/fattach/get/223683/1232386209/redirect/1/filename/BT_Freestyle_750_user_guide.pdf . The procedure to register the handset is on pages 53-54 of the manual.

I hope this helps.

No actual idea, but check user manual, go to BT website and check there (esp FAQs). Do BT have a customer helpline?

See if this helps:

Charge handset

Make sure there are not other signals interfering with the phone (wifi router).

Check to see if base and handset are on the same channel.

Hey what u doing

Having changed the batteries on my bt synergy 5500 trio it now displays that it is in test mode. How can I activate my phone so that I can receive and make calls

is possble to use 8 bt 6500 hand phones via 2 base unit on the one bt line

Partial solution. The handsets may be registered to another base.

So go into handset setting, then select base, (select another base if there is one showing).

Then go through the handset registration procedure again.

If the second handset works ok on the base and the first handset doesn't, then you are right...the fault lies with the first handset. There are batteries ( special type ) in the handset, it sound as if either the batteries are dead, or not charged ( try charging them for 12 hours on the good base station ) or the connection is bad.
