Soon after I got him this nice walkie-talkie, my brother Nenad (YU1TTL) quickly found out how to overcome missing feature of UV-B5: LCD background light is turned on only when some keys are pressed and stays on far a very short time. He managed to use flash switch which is used in UV-B6 version but in UV-B5 has no function.
He decided to put up instructions on my blog so others can benefit of this modification. So here it is:
