WARNING
Before starting the alarm test (transmission test), provide a notification to the related sections so that
they can prepare for false abnormalities (external output signals and alarm contact). After the test is
completed, never fail to press MENU/ESC key to return to the detection mode. (If the gas monitor
remains in the alarm test mode, it automatically returns to the detection mode in ten hours.)
In the alarm test mode, the gas concentration equal to the reading is output even in the maintenance
mode depending on the setting. Take actions, if necessary, so that the signal receiver side can
prepare to avoid false alarms.
