Power On. OTIS OI-315 TOCSIN3

Power On

To power on the device, press and hold the green power button for approximately three seconds.

When powered on, the device will vibrate, flash, and sound an audible alarm to verify that those features are active. After a 10 second countdown, a “V” icon will flash on the display screen and the current level of measured gas in ambient air will be shown.

When in Gas Detection Mode (Normal Operating Mode), the “V” icon will disappear

(after blinking several times).

NOTE: In the event that stabilization of the device fails, Gas

Measure Mode will not be entered. Instead, a blinking “X” will appear on the display screen. The “X” indicates that calibration of the sensor, or aftercare of the instrument, is required.

Power Off

To power off the device, press and hold the green power button for approximately three seconds. The display screen will countdown the number of seconds remaining until the device is “OFF.”

NOTE: If the green power button is pressed while the device is not in Gas

Measure Mode, or if the green power button is not held down for the required amount of time for powering off the device, the device will remain on.
