Question about Uniden TRU8885 Cordless Phone

1 Answer

Handset is lit up but unresponsive

My handset #1 is unresponsive. It has done this before, but usually corrects itself after an hour or so. But this time it is not and has is lit up but is completely unresponsive. It did say "not registered" so we let it charge overnight and then the next morning it registered as handset #3 instead of 1. I unplugged both the base and the battery pack inside thinking that would reset everything, but it is still unreponsive. The battery shows only one car of power.....maybe I need a new battery pack?

My phone displays out of range how to correct

This sounds like a registration problem. Try
de-registering the handset(s) and re-registering
to your base.

NOTE: the CS6429 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 ]

(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 !!

Need to fix date and time onToshiba DKT2020-SD

Depending on the type of system you have powering the 2010,this should take care of it.
Leave the handset on hook, press intercom # 6 5 2, then enter the time of a 24 hour clock, entering 2 digits for the hour, 2 digits for the minutes, and 2 digits for the seconds – enter a leading 0 for any single digit entered,
press Redial,
press Speaker.
This must be done at extension 200 – usually the receptionist phone.
For example, if the time is 2:15 P.M., press intercom # 6 5 2, 1 4 1 5 0 0, Redial Speaker

"out of range"

I have a GE DECT 6.0 Digital phone (silver, 2-handset model) and one of the handsets began displaying "Out of Range" and was unresponsive. We've had severe lightning around here in recent days which interfered with the digital tv reception, so I'm pretty sure that's what caused the problem. Here was what worked for me:

- unplug base unit for 15 seconds
- press "PROGRAM" button on handset
- from menu, select "HANDSET SETUP"
- from menu, select "REGISTRATION"
- handset display will prompt you to press and hold PAGE button on base unit for 5 seconds, then press "PROGRAM" button on handset

This action re-initiates the transmission between the base unit and the handset.

Good luck!

Can't get handset to register

After each registration of a handset, you need to hold the page button on the base for 5+ seconds. If you then get an error tone, you'll likely have to return the phone due to a hardware problem. What did you do?

How do you program phone for headset mode on sts phone and where do you plug it in?

Some phones have jack on the side of the phone. If it does not, you will need a standard telephone headset with amplifier. You will need a handset button (634) programmed on the phone. Then in programing Flash 50 button 4 you will need to disable speakerphone. Flash 50 button 18 determines the headset type: 0-is amplified unit plugged into handset cord, 1-is 2.5mm jack on side of phone,

To use handset, press handset button so it is lit, use on off to answer calls with the handset.

Problems with C110 & A110 Vtech Mirage Dect Home phones

Have strangely got the same problem - about the same time you posted this, but intermitently. I have isolated that the problem is in fact the handset itself, not the base unit. I eliminated a problem with the base unit by a) registering a different DECT phone to it. - The base still works fine. b) Leaving the handset switched off for an hour or so (press and hold the "OK" botton to switch off / on); then whislt it was working, registering the handset to a different base (Base 2). And guess what, after 30 mins the "BASE 2" message started flashing on the faulty handset.
So, if you already have an A110 extension handset, make sure it's also registered to base 1 and maybe try to get just the handset repaired via VTECH. (or just buy a new handset if they are available).

Only one handset can be registered at a time. The handset ID for the supplied handset(s) was assigned at the factory, which has #1 or #2 in the display (#2 for models that have two handsets in packaging). When you register additional handset to the base, the handset ID will be assigned. 1) Before registering the extra handset, the battery pack must be charged for 15-20 hours. 2) Place the extra handset in the main base unit to begin registration. 3) While the handset is registering, 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.
