When the monitor is powered on for the first time, the CO
2
module enters the
STANDBY mode by default. To activat the CO
2
module, you must change the work
mode to MEASURE. The work mode of the CO
2
module keeps unchanged when the
monitor is restarted. For instance, if the monitor is power off when the CO
2
module
is working in the MEASURE mode, the CO
2
module will automatically enter the
MEASURE mode after the monitor is restarted. For details about WORK MODE,
please refer to the section Other Setup of 17.4.3 CO2 Setup Menu.
