Handset reset / re-registration problem

Motorola E51 MD7161-3 5.8 GHz Quad Cordless Phone (base unit with 3 handsets) no longer detecting handsets. The handsets suddenly stopped working and continuously displayed "SEARCHING" and/or "CHARGING". Attempts to reset and de-register / re-register as suggested by Motorola's Online Tech Support barely succeeded only for a while but ultimately failed. De-registration resulted in the handsets all displaying "ENTER BASE ID" continuously despite repeated entry of the correct Base ID. The problem seems to be in the Base unit's recognition circuitry because the message answering system still works fine, handsets are lit up o.k., keypads work normally, etc. In fact, one of the handsets was detected and worked for a while after persistently entering the base ID within a 2-day period. Then another handset was detected and worked briefly after another 2 days of persistent entry of the base ID. However, once the AC power and handset batteries were removed in an attempt to relocate the system to see if that would help then all handsets just display "ENTER BASE ID" continuously. The message answering system still works as usual without any problems, though. I really would like to get this system working again because it's got just the features I need. However, if all else fails, then I am looking at online reviews of the new Panasonic DECT 6.0 KX-TG9332 or KX-TG8232B and will consider one as a replacement.

Can you offer any new solution for the Motorola E51 MD7161-3 problem? If none, have you reviewed the new Panasonic DECT 6.0 KX-TG9332 or KX-TG8232B yet and would you recommend either one?

    I'm having the same problem with a single handset - let it go "dead" for too long, and it continually prompts for the base id number no matter the number of times the base id is entered.... help!

  • SOS505 Jun 25, 2008

    In the middle of a conversation, the handset just goes dead and "searching" appears in the screen apparently looking for the base. Leave it alone for a while and then it is fine again. That is, until next time.



    The problem happens with ALL 3 handsets and seems to be more of a problem for conversations lasting more than 10 min.

    One of my three handsets constantly displays Enter Base ID no matter how many times I enter it. Deregistration/reregistration of all handsets did not help. Two other handsets were re-registered correctly with the same Base ID. Is there any way to reset the handset?

I had the same message. After a length investigation, I found it was the phone line and not the phone. After having the phone line fixed, the phone worked fined.

SOURCE: I have a cordless phone that every time I try to make a phone call the busy signal comes over my phone how can I correct this problem

Are you getting a continuous busy signal, or just five or six quick beeps then a dial tone?

If the latter, you have unheard messages on the voicemail system provided by your telephone company. This system records messages when someone calls while you're already on the phone. Please contact your telephone company for instructions on accessing their voicemail system.

If the former, please add a comment to this question and specify the make and model of your phone.

SOURCE: Handset says "Out of Range". What does that mean; how do I fix it.

out of range means it can't receive a signal from the base station. The most likely problem lies with the base station. Special when 2 or even more handsets are giving this message.
Try to reset (unplug the power cord and reinsert it) the base station. When it does not come back after half a minute, the station must have a major problem.

I have a Motorola L404 cordless phone. i bought an additional handset. I cannot get it to register with the base unit. It just keeps saying "registration failed"


On the Motorola L404 series, to deregister all handsets you unplug both the phone and power to the base station. Press and hold the 'find' button while plugging the power back in. The display will show "CL". Continue to hold the find button till the display shows '00' and all the handsets will show 'unregisterd'. You then proceed by registering all your handsets again in the order you want them listed.

Can not get the second handset to register to the base


This is the registration procedure

Step 1: press MENU-6 and select 3 “SET BASE”
Step 2: press the REG key on the master base
Step3: press register to finish the registration procedure.
• After the registration complete, handset 11 and handset 21 can
2-WAY intercom with each other

If issue persists reset the unit start registration by using 2nd unit that currently unable to register. if issue continues please inform for further troubleshooting

Good Luck

Place the handset into the base station (not the charging station) so it can resync to your base.

Tesco ARC200 Cordless DECT Phone


[ARC20x User Guide p20: 11 Handset Registration]
To register a new handset:
  1. Press and hold the HANDSET LOCATOR on the base unit until you hear Registration tone (repeated 'beeps')
  2. On the handset, press the PROG then the UP or DOWN button to display "REGISTER"
  3. Press the PHONE/OK
    -> The display shows "BS 1234". If any of these numbers is steady (not flashing), then the handset is already registered to that base unit.
  4. Press 1 to select base unit number 1
    -> The display shows "BASE PIN _ _ _ _"
  5. Key in the system PIN (default 0000) and press the PHONE/OK
    -> The display shows "WAIT _ _ _ _" for a few moments, while the handset searches for a base. Then it shows a list of handset numbers which are still free on the base unit.
    (For example, "1 34 6" indicates that numbers 1, 3, 4 and 6 are free; 2 and 5 are already assigned to other handsets.)
  6. Key in a free handset number
    -> After a moment, the display should show the handset's name and number.
If registration fails...
  • Try again, making sure you begin step 2 as soon ans Registration tone starts.

Programming old handsets to a new base


Cancel the old handsets registration at the previous base unit if desired.
For additional handsets, you must register each of them at the new base unit. Only one handset can be registered at a time. A handset will be assigned anextension number at registration.


Make sure the base unit and the other handsets are not being used. Program the same way as the extra handset you bought.

Registration must be completed within 1 minute.

PROBLEMS with phone


Had the same issue. I have two units each with a handset, and one handset went to "out of range" status and stayed that way even after recharging. I tried to register it with that base and no luck. I then tried to register it with the other base and it worked. Then I tried to "swap" the handsets and no luck - it seems that the registration process on the one unit is toast so now I can only use the handsets with one of my two base units.
