. . .
in Singapore - every time I
changed batteries I had to reset date and time, took a couple of tries to turn on again but eventually came on and all well
until next battery change, same procedure. I haven't done much photography since, but went to
Japan end of March and as we needed to travel fairly light decided to only take "Pentax Lithium" battery. The first day there was wet and that's when problems started again, but with perseverance I was able to take some photos. The next couple of days were cold and problem got worse so I resorted to using video camera for still images.
So while I have being trying to find a company to service camera,
I removed the battery and had left it out of the camera, 3 days ago i put the battery back in - and the camera hasn't malfunctioned since, turns on every time no problem!!!!!
But still going to send for service and clean, over 11,000 clicks, never been serviced or professionally cleaned.
