3-3 Dial receiving test
If you place all "LINK SELECT" switches (1 ~ 4) of SW-A on the CPU-55 in "OFF" position, conversation is
impossible but the dial code from each station is indicated on the LED's of the PIU as dialed. Use this to find
the cause of any fault of receiving dial information.

3-4 The order of link usage.
After power is on, links are used in numerical order for each communication.
Remember this to help you when problems are found with specific links.
Remarks:
1. Be sure to avoid mistake at time of DIP switch installation and No. 200 Programming since such mistake may
lead to trouble later.
2. Be sure to make "No. 200 Programming" after "Function Registration List" (attached to this manual) is filled
out. Keep the finished "Function Registration List" (Initial Checking Sheet for the System 133-21-024-4)
as a part of complete drawings for each installation.
