7. Inserting batteries and battery service life
Disconnect the device from the power supply and remove nurse call cable (if
used) from connector X2 before opening the lid.
Product operates with 2 pcs high quality AA size 1.5 V alkaline batteries (operating voltage
2x1.5V = 3V). Install and remove the batteries as follows:
1) Open the lid by removing the screws and lifting it from one side (for first-time assembly:
the screws for the lid can be found in the pouch containing wall mounting parts). (picture 9)
2) Insert two high-quality AA size 1.5V alkaline batteries into the device following the
polarity symbols at the bottom of the device. Close the lid and screw the screws back on.
(picture 10)
The easiest way to remove a battery is by lifting it from the + end. (picture 11)
Estimated battery life is 3 months when using high quality alkaline batteries with 2800 mAh
capacity (2pcs). Estimation is based on measured battery consumption in various
conditions and then a calculation where device is on 50% of time (shut down 50% of time)
and of that 50% of time there is someone in bed 75% of that time, there are two
notifications per day and sound notification is on 30 seconds each time.
When the batteries are getting low, the red LED will begin to flash slowly. A
“beep” sound will be heard after every 1.5 hours and the dry-contact output will
give a low battery notification after every 3 hours.
NOTE! All alkaline batteries start to leak when empty, and a leak will
contaminate the device. Remember to replace the batteries at least once a year
to avoid any leaks. Remove the batteries when the device is not being used or
when it is being stored for an extended period. Disconnect the power supply
briefly to test the batteries. If the batteries are empty, the red light on the control
unit will flash every fourth time compared to blue light. The X2 connector and the
connected system will also trigger a notification. Replace the batteries when
necessary.
