Batteries should be replaced when a battery symbolappears on the display to indicate that batteries will need to be replaced in the near future. Replace the batteries before they are completely discharged. The batteries are located on the inside of the electronics. First, unlock the drawer, remove the battery cover and replace it. The drawer operates on standard AA batteries.
Battery replacement process:
- Unscrew the battery cover
- Remove the battery cover
- Remove old batteries
- Insert new batteries - watch for polarity
- Insert and tighten the battery cover
If the batteries are discharged to such an extent that the drawer can no longer be opened, indicating the crossed-out battery symbol on the screen, the smart parcel box must be opened using external power. To do this, attach a 9V 6LR61 battery to the metal pins located on the front of the electronics. The polarity of the connection does not matter. Hold the battery so long that it provides enough power to the electronics to unlock the lock in the traditional way (with the phone) and replace the batteries.
