Smoke is in the battery compartment,has ABC ,mine is in the middle for smoke, the volume is the white knob next to the battery door

of for pete's sake. Now that I see the white knob I cant believe Ive overlooked it all the times Ive been scanning the tank for it.
Which reminds me that I should go to the eye doctor and get my eyes checked...hmmm maybe that manual is sitting somewhere right in front of me...
Thanks hdbeast and OwlsfanDan
