My handset is display only searching, I cannot make or recieve calls & it is just flashing 88

If there is an error code with an E followed by a number or "88" displays/flashes it would be an internal issue in the base unit. Uniden does offer a limited 1 year warranty (Covers Manufacture Defects ONLY, if caused by a power surge or power outage or any other type of damage that is not a Manufacture Defect this is not covered under warranty) off the proof of purchase. The proof of purchase is required for warranty service.

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

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"


Now you want to register the phone again.

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.
You should now have a dial tone

my handset is display only serching,I cannot make or recieve calls & it is just flashing 88

I just got off of the phone with Uniden for the same issue with my D1680-4. The alternating "8" - "88" code is an indication that the base is dead. They will be sending me a new base (and 2 handsets). During the call I learned that if you do not have a receipt, Uniden warrants their phones for up to 15 months. The advertised 12 months, plus 3 months for the product to get from manufacturing, through distribution channel and finally sale to the consumer.

There can be a lot of different things that could cause this. The first thing I would do is disconnect the telephone cord from the Uniden phon eand connect it to another telephone and see if you get a dial tone from it. If you do then we know that the telephon eline and the cord are OK so we go back to the Uniden telephone. Next, does the unit light up when you plug it in? are you sure that the telephone is getting AC Power? Are the displays on the handsets working? Does the handset display show "Handset XX" or does it show "Searching"? If it shows "Handset XX" then the base unit is getting power, if not the base unit may not be getting power.
If the base unit is getting power and the handsets are working and the power cord and jack were proven good by conecting another phone to them, then you would need to call uniden Customer Service for further trouble shooting or repair/replacement. the number is 1-800-297-1026

Thuis was hard to find but it worked for my ra2364hh's
note the phone stopped working in "tone dial" after 2 months and now functions with "pulse dial" only.....

Registration The handset and base will be pre-registered with a digital security code identification, which is stored in the phone’s memory, so that your phone will be ready to work right out of the box. However, your phone also has a procedure to allow you to re-register in case the link is lost accidentally. Enter menu, press the key - Select REGISTER and confirm PIN CODE will be displayed, enter the PIN code (the default value is 0000) and confirm. SEARCHING will be displayed while your handset is in registration mode Press and hold the Page key for 3 seconds on the base until the “In use” LED is ON, putting the base in registration mode SUCCESS will be displayed. This means the handset has located the base, and will get a handset number from the base that displays after the handset name for internal calling. If the handset does not locate the base, FAILED will be displayed and it will return to the non-located display mode that displays BS SEARCH with the antenna icon flash. Try again and check that you are not in an environment with interference. Note: Your base can register up to four handsets. If you have more than one handset, repeat the above steps to register each new handset.

TESTED IT 2 minutes ago and it WORKS.....

tony

Unplug the batteries for 30-45 seconds. Reinstall, and attempt to re-register the handsets to the base.

if it working & u can recieving call,its only about its display.it must replace

You need to reset the main base unit. Unplug the power from the back of the base. While the power is disconnected, press and hold the delete key while reconnecting the power. Wait for a long beep tone. When the display shows 88 or P, press play button one time. If you have a phone without an answering machine, disconnect the power from the back of the base, press and hold find hs button while reconnecting power.
