Intermittent speaker feedback during calls

There are usually two reasons why this happened one is it will happen only when you have the speaker turned on which causes feedback and creates an echo if you do not have the speaker turned on when you're not using any Bluetooth earpiece you might want to try one that would help another option when you get an echo is because the microphone hole may have something stuck in it like like food or a very carefully making sure that microphone is clean it's a small hole I have to assume I have to I have to assume that the phone has not been taken apart because if the phone was taken apart and put back together properly in the microphone wasn't seated properly it can create this Echo effect as well

When looking at the front of the unit. The metal grill has 4 crimped tension points on top, 4 on the bottom, and 2 on each side (total of 12). Use a small flat screwdriver to gently pry them forward, I just gently pulled on the top four, starting at one end and working towards the other. Then gently lift the grill off.
Then there are 8 P1 (#1 Phillips) screws on the front. There are also 2 Phillips screws on the bottom, 1 under each of the rubbery feet.
Once they are all removed (10 screws in total) the unit simply opens in 2 halves.

Hope this helps.

*** This phone is a POS ***
I've had three of four handsets stop giving audible feedback when a button is pushed, and 2 of 4 speakerphone stopped working.

You need to gently prise off the front speaker grill. You could use a blunt pen knife to do this. After you remove the grill You will see 4 additional screws at roughly each corner of the front panel. Unscrew them and then you can use the pen knife once more to prise apart the speaker housing. Prise the housing apart from the top because two base pads hold both halves together at the bottom. I hope this helps! :)

First, you will need to remove the rubberized grip on the front. I suggest that you insert a small flat screwdriver where the switch is and gently pry up the rubberized grip. Work around it until it is free. You will then see two screws at the bottome. Remove screws and loosen the metal plate that clips on at the top. You can then gently pry the two halves of the case apart

Look for a slot on the top. There will be a gray tab in it that must be pushed in while gently prying apart the two halves of the headlamp.

Hope this helps.

Question i have to ask is 1- how much do you kno9w about electronics and 2- how brave are you. The following WILL void your warranty if you still have one.
READ ALL OF THIS BEFORE YOU EVEN START
1- Based on a poor picture of the unit that i found it looks like two screws in the back of the unit need to come out, might be four screws in there but pic only shows two.
2- With your small precision flat screwdriver push under the seam in the plastic and gently pry the two halves of the case apart, be careful as these units have snap taps under the plastic that you can't see till you get it apart.
3- DO NOT PULL ON THE TWO HALVES OF THE CASE YET. Look under the back of the case since the picture shows what looks like a button or a speaker in the back, this means wires running to something on the back half of the case, Look and see what it is and see if you can find the connectors to these things, should be small white connectors that you will have to GENTLY pull out of the connection bed.
4- Now that you have done that you should see something that looks like a cell phone battery, that's your prize, again look for the connector and gently remove from the connection.
5- replace with new battery and reverse order to install and reassemble your gps device. Hope this helps

You can get both speakers off ebay total about 7 quid, you need a star drive screwdriver, pretty straightforward just be careful when popping the cover apart, the speaker needs a bit of gentle persuasion then just pop the new ones in they work fine now

We have the same phones in our office. The feedback happens with our phones if the handset is left on the base. Picking up the handset and speaking through it as if your are on a phone call during the page should solve the problem of the feedback. If not, you may want to look at your P.A. system settings.

Here's how. Logitech doesn't cooperate on these issues. Not sure why they're so secretive, but here's the skinny.

Take the four screws out from under the batteries. On each side of the remote there are four spots (or buttons) where you have to insert a *very thin* screwdriver or blade of some type and push to separate the cases. The first set of buttons are located on either side of the "Glow" button. The next ones are on either side of the <- and -> buttons. The next set is on either side of the "Stop" and "Play" buttons. The last is on either side of the "Activities" button. Just insert a flat edge and press as you gently pry the casing apart with your fingers. Take your time and don't force it to open. Hope this helps.
