Help!
Replacing Lithium battery in Stylus Radio

Hello all. I have two Airtronics Stylus radios and they need to have the Lithium battery replaced (for memory), and would like to know if I can do this myself or do I have to send them into Airtronics (at 40 dollars per radio). Any help would be appreciated, thanks.

hi, is my same issue with a jr propo ex421ex. I opened it and found 1 cr 2032 lithium 3 v with "electrowelded" terminals on it and soldered to the board. My plan is to unsolder the terminals from the board and use 1` battery holder for that kind of battery soldered to the board, but my concern is if i need a backup 3v power supply somehow hooked up to where the battery was, and for obvious reasons of course, without the tx battery...

Yes you need to connect a backup coin cell battery before you remove the depleted one.

There have been several threads here on the details for different model TX.

Can anyone cite the thread for the Stylus? The search function doesn't pick anything up. Thanks in advance for your help.
