1. Condition of the cables
Check the condition of the cables
2. Position of the bed sensor
Check the position of the bed sensor under the mattress. The correct position is at the
chest height of the user and across the bed.
Start-up and monthly checks
To ensure faultless performance, conduct the following tests at least once a month and
when ever the device is re-installed.
Testing the absence i.e. no movements notification
1. Check that the device is on (blue light is blinking). If longer delay (3, 6, 10, 15 or 30
minutes) is in use, change that to shortest. See chapter 6.1 Setting bed exit notification
delay (DIP Switch 1 - 3).
2. Have the person lie still on the bed on his/her right side for at least 2 minutes. The
system should notice person’s micro movements immediately and the green
occupancy LED indicator will start to blink. At fi rst it blinks every second time the blue
light blinks. Then after 1 minute the device gives a short “beep” sound as a sign that
device is activated for presence monitoring. After that the green LED should blink
continuously the entire time person is in bed. If the device does not detect the
presence of a person (green LED light is not blinking) move to 16. Troubleshooting. If
the green light goes off for long periods of time and the no movement notification is
triggered, adjust sensitivity higher, 13. Calibrating the “presence / absence” sensitivity.
If the green light blinks continuously, while the person is laying still on their right side,
the sensitivity level is correct.
3. Now ask the person to leave the bed. The ‘no movement’ notification should be
triggered after the delay time (3 or 5 seconds, 6.1 Setting bed exit notification delay
(DIP Switch 1 - 3), when the person has left the bed and no one is touching the bed,
sensor or wires. If the notification doesn’t work and the green light continues blinking,
see 16. Troubleshooting.
