P7100 PTT Not Working

[rfradioconsult]

My P7100 has developed a problem wi the side button PTT, it started as an intermittent you could hold the PTT down and tap the case and it would show TX. Now it won't key from the PTT; however it keys from an external speaker mic. I am guessing it may be a flex connector problem but haven't opened it up yet. Any hints would be appreciated, I need to modify the programming but cannot put it into programming mode. FYI I use Programmer 18B, don't want to upgrade to RPM.

If you have access to Programmer, Just change key pad settings to one of the other buttons on the key pad to see if the flex connector is the issue,

Without a functional PTT button you cannot perform a 3 finger salute to put it into programming mode, cannot be done usind the speaker/mic ptt.

This is a VERY common problem with the P7100s and P5100s. Jaguars, too.

Under the PTT is a square piece of rubber which contains the rubber PTT actuator, which
provides the mechanical connection between the PTT button on the housing and the actual PTT
switch on the inside of the housing. This piece of rubber deteriorates and turns to gum.

You remove it and install a new one. Part number of the kit is G4UK07720, PTT button kit.

Thanks,

I've got TAC's number but don't have parts telephone number handy.

Same number, different menu option.

Thanks for the part number, I have 2 on order from NLT.

All my P7100's have that issue - but you know what, it makes for a nice "feature" as we all use speaker mikes and it prevents accidental PTT actuation when you have other stuff on your belt.

But it really makes it difficult to get it into programming mode!

Before I dive right in could someone pass along the Cliff Notes on how to do it the right way, before I fumble the job.

Replacing the PTT button?

It's so simple that I refuse to give detailed directions. It's easier than changing a light bulb. You do it from the outside.

Pry off the PTT button with a thin screwdriver tip. That's how it starts. The rest is self-evident.

Thanks that was what I thought, but wasn't 100% sure, I didn't want to open the radio if I didn't have to or break a tab in the process.

 

[rfradioconsult]

Job complete, was able to get into programming mode and edit the info.

Question- how do you get the PTT button to fit back into position after prying it off?

 

[rfradioconsult]

I used the shaft of a jeweler's small screwdriver placed about midway to act as a fulcrum to allow enough flex to get the top clip to snap into place.

Clip one side in, then use a screwdriver to force the PTT button to "arch" so you can clip the other side in. It's super easy.
