H19txt Disassembly

I was moving a cabinet on a hand-truck when it fell off and I tried to catch it. My earpiece was in my pocket when I tried to catch the cabinet, and the earpiece got squashed. It still works, but the microphone no longer picks up sound well enough to hear.

So, for the sake of sharing, I decided to disassemble the H19txt. It was already broken, so any further damage wouldn't matter to me. Obviously, I'm not responsible for any damage caused by following the same procedure I list here.

First I removed the top gray cover. If you use a sharp knife and pry it towards the center, it should release the clips and pop off.

Next, remove the plastic trim by prying away from the body. These two pieces were already damaged from being squashed between my thigh and a falling cabinet.

The flip easily comes off by prying the clips wider. One end fits over a square side that activates a switch on the circuit board. The other end is rounded. It's the same basic style as the H17. I broke the flip on my H17 and ordered a replacement. The replacement was the H19 style. The replacement didn't have the rubber bumper on it that made it close softly. That's one feature from the H17 that I like better than the H19txt.

 The circuit board can be removed by first prying up on the USB connector end. Then carefully slide it towards the USB end of the earpiece.

Underneath the circuit board, we can see the lithium ion cell. It is taped in, and can be removed by prying it out.

For my replacement H19txt, the first thing to do is to hold the call button down when opening the flip to get to the settings menu. I turn off the voice prompts so that it takes less time from turning on to being able to talk when I answer the phone.

So, if you have an H19txt and want to replace the battery or something, I hope this helps.
