Setting the Code
On the Entrance Station, there is a digital display for the code. We recommend using the
first digit to represent the address, the second and third digits for the floor. This will not only
make it easy to remember each unit’s number, but also help with maintenance.
Example 1: To represent the room station located at No. 1, 8
th
floor, use the code:
1 08
08 to represent the 8
th
1 to represent No.
Example 2: To represent No. 2, 9
th
floor, the code would be 2 09
