YOU might need to deregister the hand set first by holding down the red end (hang up key) and keep it down while holding the # key. If deregister wont work use base unavailable and yes, you are sure twice.

List the handset numbers of those working handsets
Using a WORKING handset follow these directions
Resetting Handsets
If you want to register the handset to a different base or
replace a handset with another one, you must first clear the
registration information from the base and the handset.
1. Press and hold [ ] and [#] for
at least 5 seconds, until the
SYSTEM RESET menu
appears.
2. Select the DEREGISTER HS
submenu. WHICH HANDSET?
appears in the display.
3. Move the cursor to select the handset ID to be de-registered
from the list, and then press the OK soft key. DEREGISTER HS
appears. CHOSE A NUMBER THAT IS NOT ONE OF YOUR WORKING HANDSETS
4. Move the cursor to select YES, and then press the OK soft key.

First make sure you clear the registration on the problem handset. Go to the handset, menu, select de-register; and select yes. Bring your handset next to your base, on the base unit menu select register handset. On the handset, hold the # for 2 seconds. You should see registration completed. Good luck.

Hello
Connect the phone line and power UP the base unit. Place the handset on base to get charged. It must reset automatically when you place the handset on base to charge. If not; resetting both handset and base unit is necessary.
Resetting the Handset

You may need to reset your handset in the following instances:

You lose a handset and purchase a new one. When you try and register to your existing base you get registration

failure.

You are unable to register any handsets to the base.

You had a base which needed to be exchanged by the manufacturer. When you register your existing handsets

to the base, the handsets say #3 and #4, but you only have 2 handsets.

When you are instructed to by the one of the manufacturer's call center representatives.

To reset, do the following:

Press and hold [ ] and [#] for more than 5 seconds. Select DEREGISTER HS.

WHICH HANDSET? appears. Select the handset that you want to de-register, and press the OK soft key.

DEREGISTER HS appears. Select YES, and press the OK soft key.

ARE YOU SURE? appears. Select YES, and press the OK soft key. You will hear a confirmation tone. The

handset will clear its registration information from the base, and then delete its own base information.

MODELS VARY! PLACE HANDSET ON THE BASE FOR REGISTRATION OR REFER TO OWNER'S MANUAL. To

re-register the handset to the base (see page 25).

If the handset cannot contact the base, it will display OUT OF RANGE. Make sure the handset is in range of the

base and the base is connected to power.

Note: It is also possible to reset the handset back to its original factory settings. All changes including Caller ID information

will be erased. For more information on resetting the handset back to factory settings and when you need to

do this, see www.uniden.com or call our Customer Service Hotline. See back cover page for contact information.

Resetting the Handset without the Base

If your original base is not available for some reason (for example, it is lost or somehow incapacitated), you can still

reset the handset and use it with another base.

Press and hold [ ] and [#] for more than 5 seconds.

Move the cursor to select BASE UNAVAILABLE and then press the OK soft key.

BASE UNAVAILABLE appears.

Move the cursor to select YES, and then press the OK soft key. ARE YOU SURE?

appears.

Move the cursor to select YES, and then press the OK soft key. You will hear a confirmation tone. The handset

will delete its own base information without trying to contact the base. When the base information is deleted,

the handset displays MODELS VARY! PLACE HANDSET ON THE BASE FOR REGISTRATION OR REFER
TO OWNER'S MANUAL. Register the handset to the new base (see page 25). of its user manaul.
OK.

What happened is you have deregistered your handset from the tru9488 base. To correct this, you must register that handset with the base. See https://www.manualslib.com/manual/185023/Uniden-Tru9488.html?page=24 for short and sweet instructions for doing this, reproduced below:.

I need to deregister missing handset #1


To de-register HANDSET #1:

1) Grab any working handset which is registered to your base (so HANDSET #2 or #3 in your case)

2) Press and hold the "END" + "#" key for 5+ seconds (wait for it to beep)

3) Choose the "Deregister HS" menu option

4) Pick HANDSET #1 as the handset ot de-register (since that's the "phantom" registered handset)

5) Once de-registered, you can de-register handsets #2 and #3 directly from each handset's "normal" menu interface (i.e. press "Menu", choose "Deregistration")

6) Thereafter, if you re-register your handset, they should start at HANDSET #1, then #2, and so on.

ADDING HANDSET SAYS OUT OF RANGE


A search of Uniden support only said to call 1-800-297-1023 with handset registration issues. The rep picked up quickly and walked me through the reset procedure. Here it is step-by-step:

1. Remove battery
2. Hold down the * and # buttons and reinsert battery. You should hear a long beep. If not retry. (This is a bit awkward but hold the handset upside down and it's workable)
3. Screen will be blank. Immediately press the right soft menu button.
4. Screen will report that EEPROM is clearing and then state EEPROM Clear Ok
5. Remove battery (yes again)
6. Reinsert battery (this time there's no need to hold down any buttons)
7. Handset will reboot with Welcome screen and then state that phone must be registered (this is the status a handset should be in from the factory)
8. Place handset on base and it will register as normal

Registering DSS7905 Accessory Handsets
Your phone supports a total of ten (10) cordless handsets. Handset(s) supplied in the box with the phone base are
pre-registered at the factory. If you purchase an accessory handset, you need to register the handset before use.
Only one handset can be registered at a time. When charged, pre-registered handsets display a handset ID number.
Handsets that have not been registered display.

Before registering the DSS7905 accessory handset, the battery pack MUST be charged for 15-20 hours.
To register the DSS7905 handset:

Place the handset in the telephone base charging cradle to begin registration.
During the registration process, HANDSET REGISTERING will appear in the LCD. When REGISTRATION
COMPLETE. is displayed; the handset has been registered to the base. If REGISTRATION FAILED. appears,
please try these steps again. When you register an accessory handset to the base, the handset ID will be
assigned.

Note:
If an accessory handset has ever been registered to a base, you must reset the handset before you can
register it to a new base. See Resetting the Handsets on page 24.

Deregister lost or broken phones


Some tricks from a helpful Uniden rep:

holding down end+# keys at the same time on the phone for about 10 secs (you will hear a beep) will deregister the handset. If you have a dead handset and want to deregister it from the base, you have to reset the base. unplug the phoneline and power. hold down the "delete message" key, plug power back in. about 10 secs later, you will hear a long beep (theres a short beep upon powerup as well). At this point all handsets are deregistred and you will have to reregister them with the end+# trick. this way when #1 handset is dead, you can make a working one #1 and get the broken one fixed emotion-1.gif

BTW, this is a woot warranty, not uniden warranty. however the uniden rep gave me the number to the people who refurb (rox0rz!) these. I'll post an update when I finally get ahold of them (and the number if its actually helpful)

Handset Fails to Register


It is quite possible that you'll need to go into the menu settings on your base-unit and reset the unit or restore factory default, whichever option it gives you. Also, look in the menu on the phone to see if there is an option to reset the handset also. After resetting the unit and/or handsets, try to register the handsets again, one at a time. If that still does not fix the problem, you may have handsets that are not compatible with your system, or your system may not be able to support that many phones. However, if you have the right handsets, and your system can host that many handsets, then I'm confident that resetting the unit and re-registering your handsets should fix your problem.
Hope this helps! Have a nice day!
