Question about Motorola Mobility MA550 Cordless Phone (51403400100)

1 Answer

Microphone has stopped working

The phone is about 2 weeks old. Out of the blue, the microphone has stopped working. I can use the phone to dial numbers *and* connect, I can hear the other party, but they can't hear me. BTW, this has absolutely nothing to do with the MUTE button. Any ideas will be greatly appreciated.

Re: microphone has stopped working

Check the channel switch on the transmitter unit. Change to the opposite channel and retest. Check that the batteries are still good in transmitter AND receiver unit good luck

I bought your digital cordless phones two weeks ago and now we recieve no incoming calls because they do not ring although we know that they are ringing also we cannot ring out we hear the number being...

They're not mine or FixYa's phones, they are yours.

Are you hearing dial tone before you ring out? When a phone doesn't dial or ring, it's the first sign that it's not connected to a working phone line. Try a regular phone in the same jack first.

Continuous dial tone on phone line . When i try to dial out- i just get a continuos dial tone- happening on my 2 cordless, landline is fine. Dont use a magic jack, changed out hardware, new cordless dont...

There are two possible answers to this problem. The first thing is to check on the cordless phones, is a 2 way switch, one setting is for DP=Dial pulse (setting for old rotary phones) 2nd setting is TT= Touch Tone. I would guess that the setting should be set to TT on both cordless phones for touchtone.
Second thing to do is to plug in the base unit of your cordless phone to a jack that currently has a landline phone plugged into it that works and test again. If cordless phone works OK then go back to the original jack that didn't work and reverse the wires in the jack: that is what is known as a "polarity" issue.

Enter memory data

Here are the commands to run the phones memory dial (speed-dial).  I have included the instructions for deleting and changing numbers as well.  It is listed below.  I hope this helps you out.

MEMORY DIAL INSTRUCTIONS Store up to ten 20-digit numbers in memory for quick dialing. Storing a Number in Memory 1. Make sure the phone is OFF (not in TALK mode). 2. Press the MEMORY button. 3. Press a number (0-9) to store the dialed number in that memory location. 4. Press the MEMORY button again. 5. Use the handset number keypad to enter the telephone number (up to 20 digits, including pauses) and press the MEMORY button again to save the number. The unit beeps to confirm. 6. To enter another number in a different memory location, return to step 1 and repeat the process.
Storing a Redial Number 1. Repeat steps 1 through 4 in Storing a Number in Memory. 2. Press the REDIAL button. 3. Press the MEMORY button to store the number. You will hear a confirmation tone.
Changing a Stored Number 1. Repeat steps 1 through 6 in Storing a Number in Memory. 2. Press the MEMORY button to store the number. You will hear a confirmation tone. The old number will be overwritten with the new number.
Dialing a Stored Number 1. Make sure the phone is ON by pressing the TALK button. 2. Press the MEMORY button. 3. Press the number (0-9) for the desired memory location. The number dials automatically. Inserting a Pause in the Dialing Sequence Press the PAUSE# button once to insert a delay in the dialing sequence of a stored telephone number. A pause is needed to wait for a dial tone (for example after you dial 9 for an outside line, or to wait for a computer access tone). Each pause counts as 1 digit in the dialing sequence. If you need a longer pause, press the PAUSE# button twice.
Deleting Stored Numbers 1. Press the MEMORY button. 2. Press the desired memory location (0-9). 3. Press the MEMORY button twice to delete the entry. 4. You will hear a confirmation tone.

Phone not ringing

Just recently the Innovage LED touch screen phone stopped ringing. It has worked perfectly as a home office phone since Oct. 2005. Cannot find anything in the tiny manual to correct this problem.

How does one get the handsets to record the new speed dial numbers on the base phone?

I'm pretty sure the speed dial numbers are programmed on a per-phone basis. Most people would not want changes on one phone's speed dial to effect the other phones. I know registering the handsets will not make a difference. If the cordless phone is working, it's registered to the base. This is required so your neighbor cannot buy the same phone model and use your phone line. In the old days cordless phones were permanently linked to one base but now you can get extra handsets on many systems and "register" the phone to work on your base.

Lots of static heard during use of this phone.

Time for a new phone. Most likely there are some bad solder connections and they could be anywhere. A 2 year old battery should not cause such severe problems so I'd spend the money on a new phone before a new battery.

Problem when dialing phone

Yes, I have had nothing but trouble with my V-Tech ia5823.
Slow to dial, dropping out going calls and now the base light is flashing at a rapid pace and will not charge the handset.
I want to return it to Wal-Mart but have misplaced the recepit.
I will never buy another V-Tech..Uniden is the way to go!
