4.5. Set sensitivity to notice tonic-clonic seizure
NOTE:
The sensitivity of the product must be adjusted according to the
•
user's weight
•
Adjust the sensitivity of the device every time the sensor is re-
installed and if the user or the sensor changes.
•
Test the device before using it and when the settings are
adjusted.
The sensitivity to notice fast movements caused by tonic-clonic seizure can be adjusted with the
10-position rotary switch inside. The factory default setting is 3. Increasing sensitivity may lead to
false notifications while decreasing sensitivity may lead to the notification not becoming activated
when needed.
If you feel that sensitivity is not good enough, simply adjust higher step by step. Or, if you feel it is
too sensitive causing false notifications, simply drop the setting lower step by step.

4.5.1. Calibrate the "presence/absence" sensitivity
NOTE:
Always calibrate if there are changes, such as a new bed or mattress, or if someone else
is going to use the sensor.
If you use the bed-exit (absence) notification, the sensitivity to determine that person is in or out of
the bed is adjusted in calibration mode. Increasing sensitivity can lead to false alarms while
decreasing sensitivity can lead to the alarm not being activated when needed.
The person to be monitored should be in bed and lying still (not moving or talking) for at least one
(1) minute until green light starts to blink the same speed as blue light. The monitor (control unit)
should be placed on a table, clipped on bed, or mounted on wall. Sensor should be in correct
position under mattress.
Start calibration by pressing the SW1 switch (picture 21) three (3) times. You will hear 3 low and
high tones (bu-beep, bu-beep, bu-beep). The calibration takes 18 seconds. If calibration is
successful, the confirmation sound will be the same 3 low and high tones (bubeep, bu-beep,
bubeep).
