Battery Question

When turning the battery check knob in the on position, I get a continuous hum. Is this the norm or should I get a short hum and then it stops...First time with a CZ.

That is normal. The more battery the louder it is. It gets less loud when the batteries are getting run down. The manuals are available here:Fisher detector manuals

There is another thing that will alert you to the batteries being low..

...if you are in pinpoint and the sound just fades away completely--you have a few minutes left. (the continuous audio drains the batteries faster)
Let off and scan in disc. you will probably get a signal. :biggrin:
