They hold if left on standby. I replaced the internal 3 volt lithium battery which I assumed was providing power to the memory chip when power was disconnected and I thought that this had cured the problem but it seems to have returned. No apparent loose connections and the battery is correctly connected re polarity. Any ideas please as to what else I can try?</p> <p>&nbsp;</p><div style="clear:both;"></div>
