I mentioned recently under the heading of Degen 1102 vs. 7600Gr that I
hadn't noticed the sleep timer on the Degen 1102. It IS there.
Actually, it's quite accessible and can have an input of from a few
seconds to 99 minutes. I know the manual tells us it exists from 01 -
99 minutes, but it depends on where the seconds are (or how close it is
to the minute change) when the timer is set. The minute you are in when
it is set is counted as the first minute and can be from a sec. or two
up to a full minute.
