■ How to Use the Alarm/Control Terminals
These terminals are used for emergency recording, auto time adjustment (Auto Adjust Time), taking measures against power
outages (Shutdown Time), and when installing a buzzer, a lamp, and such an alarming device. They are also used to synchro-
nize with the sequential display changeover.
The terminal pin array and connections are exemplified
below. The connector to be used should be manufactured
according to the pin array.
