Hi folks, I was wondering if anybody know a way to silence or quiet a Gralab 505 WHEN using the keys to enter the time? Right now, it beeps quite loudly every time I press a key to try to set an exposure time. Since I do most of my printing at night, and live in an apartment, it would be great if I can quiet or just silence it completely. I read online somewhere somebody took it apart, but I have no idea how. So far, I have been wrapping it in clothes, and really hold the wrap tight when pressing the timer buttons. It sort of deadens the sound slightly, but def not a long term solution. Any suggestions would be greatly appreciate it. Thank you.
