Doro 5055 handset register

Yes, it looks they are compatible. I would guess you need to set up from scratch. Remove all power to base unit and handsets, batteries to handsets, and phone line and start from the Base unit, to powering handsets again.

Registering a Handset

If you see a "not registered" message on a handset, you must register it to a base before using it.

1. On the base, open the menu and select "Register Handset"

2. On the handset, press and hold POUND (#) until the handset display says "Handset Registering" (about 2 seconds).

3. Wait until the handset display says "Registration Complete" (about 30 seconds), then pick up the handset and press eND/CleaR.

# If you don't hear a dial tone or the display says "Registration Failed" charge the battery completely, then try again.

This sounds like a registration problem, each 'old'
handset must be de-registered from its original
base and then registered to the 'new' base.

NOTE: the CS6229 handles a maximum of 5
handsets. If you have a handset displaying
"Handset #5" then you have a 'fully populated system'
even if you actually have only one or two handsets.

You will need to clear each handset ( I ) then clear
the base of all registrations ( II ) before re-registering
each handset ( III ) up to the maximum of five.
=====================================
( I ). First, to de-register a handset ---

0. Start by taking off the battery compartment cover.

1. press [menu]
2. scroll up/down to "Settings"
3. enter * 7 8 9 0 #
4. scroll down to "next page", press [select]
5. scroll down to "Register Clear?", press [select]
6. display asks "Confirm?" or "Register Clear??",
press [select]
7. display reads "Ok" and chirps, press [ off ]

8. UNPLUG THE HANDSET BATTERY
(this is why the cover was off)

9. Wait ~30 seconds, re-connect the battery &
replace the cover

10. display reads "Not Registered"
===============================

( II.) To clear the base of all handset registrations
( if needed, else skip ahead to ( III ). )

1. press [Find Handset] on the base and hold
past ~4 sec when the "In Use" lamp lights, at
about 10 secs the "In Use" lamp will begin to
blink. 2. release the [Find Handset] button momentarily,
then briefly press it again. After a moment,
all handsets that were registered to the base
(if any) will display "Not Registered" and be
ready for fresh registration ===============================

( III.) To register each handset to the base:

1. press [Find Handset] on the base and hold for
~4 sec until the "In Use" lamp lights.
2. press # on the handset and set the handset into
the handset cradle on the base
3. within 30 seconds or so, the handset will either
chirp and display "Handset Registered", then
"Handset #x" or it will say "Registration Failed".

NOTE: the battery must be well charged prior to the
registration process, a weak battery may cause a
"Registration Failed". Charge the battery for a
few hours and try the registration ( III ) again.

===============================
Good luck !!

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!!
===============================

This problem can be caused by the following, A bad battery, (which you say you are all new). A full base memory and a Faulty main base unit
This main base unit can only expand to four handsets and no more. If the base unit has been reset then the assigned numbers for each handset would begin with " handset 1" if they show any other number when reset then it would not have been reset..To re-set main base you will have to
De-Register All Handsets
Unplug the power supply from the base unit then Remove all handsets from the charge cradles and base then Press and hold the PAGE button on the base.
Plug in the power supply again while pressing the PAGE button, Continue pressing PAGE until the IN USE and CHARGING indicators are lit. (this could take up to 10 seconds)
Release the PAGE button All Handsets will display "enter base id".
If this does not solve your problem then you will have to replace the main base

Hi,


This is because the extra handset might have not been registered with the base unit.The headset should be register to use the headset with that base unit.

To register the handset to base unit please follow the instruction:-

On registration the handset is allocated a handset number for use on the new base unit, the handset numbers are 1-5.

1. Press and hold
on the base unit until starts flashing. Registration mode will remain active for approximately 3 minutes.

2.Press and hold both
together until you hear a long beep.

3.Select the base unit you wish to register by pressing the corresponding number button 1-4.
4. When PIN is displayed, enter the units PIN number (0000 for this model).
5. If the registration is successful the handset will return to standby mode in a few seconds.

Thanx

you dont need to deregister it if you have not registered all 8 hand sets with your base unit. Just register the new one and the base will assign a new # for this new. I you had registered 8 hand sets with your base already, you need to remove(deregister0 one handset from your base(it can take only upt 8).
If it still not registering please deregister as follows:
on the base unit, press program, them mute, then enter 335#, then enter the handset number you wish to deregister.
after deregistering try to register your new hand set.

Short answer:
No. This model of phone can only support 4 handsets. If you need more than that, you will need to have a second base unit.

Detailed answer:
One of my handsets went bad, and I just bought complete DCT748-4 package from a seller on eBay for a very good price. This set was used, but in very good condition. I didn't need the whole set - just one handset - but like I said, it was a good price. Anyway, I began by telling my old base unit to de-register handset #2 (the failed unit). However, I then found that I could not register the "new" handset with my old base unit because it was already registered to the "new" base unit. So, I first had to apply power to the "new" base unit and de-register the handsets. Then, I placed one of the "new" handsets onto my old base unit, and it said "Handset Registering ..." and registered just fine. Just for the fun of it, I placed one of the other spare handsets into my old base unit. It said "Hanset Registering ..." but then it beeped and said "Registration Failed." This is because I already had 4 handsets registered to my base, and the base can not handle a fifth handset.

Step 1: Press and hold FIND HANDSET on the main telephone base for 10 seconds.

Step 2: When the IN USE light starts to flash, release the FIND HANDSET button.

Step 3: Press and release FIND HANDSET again. The IN USE light will turn off and in a few seconds, all handsets will be de-registered.

Step 4: All handsets will show NOT REGISTERED.

To register a handset (register 1 handset at a time):
Step 1: Place the handset in the base unit or a charger that is connected to a power outlet. If PRESS FIND HNDST 4 SEC ON BASE does not appear on the screen after a few seconds, lift up handset and place in base or charger again.

Step 2: On the telephone base, press and hold FIND HANDSET for four seconds. Release FIND HANDSET once the IN USE light comes on.

After a while the handset will emit a series of tones, the newly registered handset will be assigned the lowest extension number not previously assigned to another system handset (1-4) when successfully registered. Repeat Steps 1 and 2 if the handset does not successfully register to the telephone base within two minutes.

Check that you have the larger power adaptor connected to the base unit.
