Question about Motorola Mobility SD4581 2.4 GHz Digital Cordless Phone (51960700100)

Open Question

Strong echo for my voice

My Motorola SD4581 which worked fine for the year and a half I had it, suddenly developped a loud echo of MY voice (other party in conversation hears me well), so loud that i cannot really talk. This is the same for both handsets. Is there anything that I can do? It really upsets me, I certainly expect a phone to work for more than the paltry 1 year warranty...

I would try reseting the system... to do so uncover the batterie compartment and then and find a litthe tiny button that says reset and press it with a pen/pencil or somthing that will fit and try again... if that doesn't work call your dealer and ask for a refund/replacement. i hope this helps

SOURCE: motorola md7161 keyboard not working

I know you may not have experience in taking apart the handset or small electronic repair but, it is actually very easy to do. I just bought the same phone set from goodwill for $6.99. The set looks great and actually almost in new condition.

However, I had the same problem with just one handset so, I figured it out so, my set would work properly and now after I fixed it, I have no problems and every handset works great.

Follow these instructions step by step and I assure you it will work again like new.

Step 1.) Take the battery cover off on the back of the handset and pull the cord out carefully from the battery wire to where it connects to.
Step 2.) Unscre the two screws that you see inside. Then, carefully seperate the front cover from the inside of the phone to gain access to the inside of the phone so, you will have access to the 3 small screws that will seperate the circuit board to gain access to the keyboard.
Step 3.) After removing the circuit board and taking out the keyboard and rubber keyboard pad. Carefully wipe all of the buttoms very rigously with an alcohol wipe pad and you will start to notice some plastice film start to come off. This is what you want to remove beacuse, somehow it causes those keys to stick.
Step 5.) After wipeing them clean and reinserting the pad to the cover, the screws in the holes, aliging everything back together and snapping the cover back on, screwing the 2 screws back in and replacing the battery and cover. Test it and you will se that it works just like it did when the phone was brand new.

Hope it worked for you like it did for me and good luck. :)

    Motorola SD4581 2.4 GHz Digital Cordless Phone won't stop chirping

    Bad contact between the phone and the base unit making the pair think they are low on battery.

    it probably wouldn't hurt to get some rubbing alcohol, and clean the charging contacts on the base station and the handset. Oxidation can build up, and depending on whether you normally leave the handset on the charger or not, that oxidation can interfere with the contacts.
