Due to Alpha 3000 series’ ID code (or address code) is 16-digit long, the first 8 digits are set via the
soldering slot and the remaining last 8 digits are set via the dip-switch (total of 16 digits). For the soldering
slot, the “SH8” represents the 1
st
digit of the ID code and “SH15” represents the 8
th
digit of the ID code. As
for the dip-switch, the “1” represents 9
th
digit of the ID code and the “8” represents the 16
th
digit of the ID
code (last digit). Below are some sample illustrations for better understanding on how to set the entire 16-
digit ID code via the soldering slot and the dip-switch.
Example 1:
ID code 00000000:10101010
Example 2:
ID code 01011001:00011100

All Alpha 3000 systems are also equipped with a PLL synthesized receiving RF module with up to 30 user-
adjustable RF channels. The RF channel dip-switch is located on the topside of the receiving RF module,
covered by a sliding door (refer to item #2 on page 9 & 10).
Example: For the below illustrated dip-switch “00101” setting, counting from dip-position #1 through #5,
the RF channel would be “205”, which also represents frequency “301.205 MHz”. Please refer
to the Frequency (RF) Channel Table next page or the CHANNEL _ DIP label inside the
receiver door panel.
