After Taking Measurements
If a pulse was previously acquired and then lost, the N-395
enters Pulse Search, and the Pulse Search indicator lights. The
last detected readings are displayed while the monitor searches
for a valid pulse. When the monitor considers the pulse "lost,"
it displays zeroes and a high priority alarm sounds.
When a valid pulse is detected, the N-395 exits the Pulse Search
Mode and displays the current readings. The Pulse Search
indicator goes out.

If the sensor cable becomes disconnected from the sensor or the
monitor during monitoring, a low priority alarm sounds, values
for SpOz and pulse rate are replaced with dashes, and SENSOR
DISCONNECTED is displayed on the screen.

monitoring, a low priority alarm sounds, values for SpOz and
