Hey, my IDR48 no longer wanted to start cleanly. Different errors occurred every time I started. Then I opened the housing and found that the 2.4V battery had leaked. Replacing the battery is not the problem. The acidity is more of a problem for me. Unfortunately, this has now completely damaged and peeled off the circuit board paint. I think I’ll be able to repair that too.
Now the real problem, right next to the battery is a small component. It says C2K607ES on it. Unfortunately, Google can’t help me with this matter. Who can tell me what kind of component this is? Unfortunately I have to unsolder this and I don’t yet know what it looks like underneath. And before everything is ruined, I wanted to know what that was.
Hi. This must be the crystal oscillator of 32,768 kHz according to datasheet of RTC chip DS1306.
Did you fix your iDR? Got one with the same issue right now.
Hey @nOr4d,
Yes and No 
I have replaced the Battery, clean the board an take some paint on it. After that, the board Works.
Than after 2or3 Month i tested again, but the same Issue. No Starting.
My problem was, that i needed fast back. So i buy a SQ-5
