4.14 SETTING GUARD

The guard zone alarm is effective for alerting the operator to targets approach-
ing his own ship. An alarm is sounded when any (apparent) target returning an
echo above the noise threshold is detected. If sea clutter, or other incidental
echoes trip the alarm, adjust the gain control and/or the sea clutter to avoid this
false alarming.
