SNAP8 Model SPR300


That PDF shows how to replace the battery, so maybe you missed
something?

Thank you for your reply. Mine is not the SPR-300 PLUS or the SPR-300
PLUS A in the PDF shown. It is an older model with no fuse or battery
inside and for screws in the back. I tried the web site for Sperry,
they did not list a manual for the mine.
