cause instrument damage (although internal protection
circuits can typically withstand a short-duration signal of
several Watts).
cause instrument damage (although internal protection
circuits can typically withstand a short-duration signal of
several Watts).
If the overpower circuit is triggered (signified by a
warning message at the top of the screen), remove the
signal from the ANT IN port, and reset using
warning message at the top of the screen), remove the
signal from the ANT IN port, and reset using

can
result in uncalibrated operation (a message appears on the screen when
this happens). The purpose for the high sensitivity setting is to allow
you to look and listen to very low level signals when absolute accuracy
is not essential.
