Changing Passcode for Bluetooth Pairing
The passcode for Bluetooth pairing may be changed. To change it, removed the CPS-121 from the wall
by removing the four Phillips drive screws on front panel, and locate the 8-position DIP switch centered
on the circuit board.
The position of the small switches will determine the passcode. Each switch positions represents
different value. The total value of all switches is added to 8200, and the result is the passcode for the
CPS-120 device. The passcode may be any number between 8200 and 8455, inclusive.
The first switch (with the “1” label by it) has a value of 0 or 1 (of Off, or On);
the second switch (with “2” label) has a value of 0 or 2;
the third has a value of 0 or 4;
and so forth, and as shown below.

Set the switches in any combination of ON and OFF. Then sum total the values of each switch. Add that
sum to 8200 for the final value, and that will be the passcode.
The factory default switch positions are (1 through 8): ON, ON, ON, ON, OFF, ON, OFF, OFF.
Numerically, that is . . . . . . . . . . . . . . . . . . . . . . . . . . . .1 + 2 + 4 + 8 + 0 + 32 + 0 + 0 . . . . or
47
And this, added to 8200 equals 8247. 8247 is the passcode for each device as it leaves the factory.
