FREQ: Frequency Shifting
If the detector chatters or is noisy while the coil is motionless, the cause is
either internal circuit noise due to too high sensitivity setting or from
electromechanical interference (EMI). If reducing the gain does not improve
the operation, try switching between the alternate frequency settings. You may
find a frequency option that eliminates the noise. Shifting the frequency may
have an effect on the ground balance so as a precaution; we recommend you
re-ground balance after changing the frequency.
Changing frequency may require you to change the ground balance setting.
See section on ground balancing.
LIGHT: Adjustable Backlight

from 0 to 5 in increasing levels of intensity. Use of the backlight feature will
