Icom IC R9000 clock issue

[Klarkkk]

Greetings,i am a lucky owner of this fantastic receiver. The clock (both clock1 and clock2) are stopped. Since i would like every part of my machines to be perfect, i ask you if anyone has had a similar thing happen and how they solved it. Thank you very much, Claudio IZ0NPN

Likely the clock backup battery has died.
