If your battery level indicates low, replace them by fully charged ones and bring the old ones to the ware house to re-charge them.
1. Accessing the electronics compartment :
unscrew the 4 screws on each corner of the blue bottom shelf.
⚠️ Do not (ever) use a drill to screw/unscrew the 4 bottom screws as they are fragile. Use a screwdriver.
2. Replacing the batteries in the electronic box
Remove the 4 screws at the corners of the Electronic box using a PH1 screw bit
Open the lid
Insert 2 4R25 6V 50Ah batteries in the 2 slots, ensuring the spring connectors touch the plate. They can be fitted in any way but with the spring connectors touching the contact plate.
Check if the power button is blinking blue (0.5s every 6s).
⚠️The blue led is very dim. If you don’t see it first, be sure to face the button directly and give it some shadow with your hands.
Put the lid back and tighten the 4 screws.
3. Test the opening of doors
