I own an old Pentax Spotmeter, it looks similar to the Spotmeter V but is a little different as it has 2 different batteries, 1x 9V block for reading and a smaller one fot the lightning. Now it stopped reading in the upper scale, when I press the L button for low light it works. A dude of mine is willing to repair it but he didnt get clear with it without service manual. So I am looking for a service manual or factory repair manual.
Thanks and Kind Regards
Martin
