interfere with the detector. If conducting an indoor demonstration,
turn the sensitivity down and keep the searchcoil away from
appliances such as computers, televisions and microwave ovens.
If your detector beeps erratically, turn off appliances and lights,
especially those with dimmer switches.
Also keep the searchcoil away from objects containing metal, such
as floors and walls.

Demo (p.7-8) and Basic Operation (p. 9-12).
4) Use 9-volt ALKALINE batteries only. Do not use "Heavy Duty" batteries.
