the volume difference between
small and large targets.

Volume Limit
Range: 0–30

The Volume Limit sets the maximum volume for target signals. When detecting, the
sound produced by a target can be very loud. Adjust the Volume Limit to ensure
that loud targets do not hurt your ears.

for your hearing.

For information on the Menu Button and its use, refer to page 29.
If the Threshold Level is too high, faint
targets will be harder to hear above the
Threshold 'hum' .
If the Threshold Level is too low, the slight
variation caused by a small or deep target
may not be sufficient to hear. Adjusting the
level to below an audible level will ensure
silent operation but could mask the audio
response from small or deep targets.
