put it off by pressing the ON/OFF button and start the TEST operation after 35 seconds at minimum.(The communication time with all
chambers : 16 x 2 seconds = 32seconds)
• For the reservation operation, the communication time between all 16 chambers is required for 64 seconds due to the increase of
communication data.
• The first digit (MSB) of error code displayed during the group operation stands for the address of SET where the error occurs.
