Under normal operation, gas values for each of the sensors fitted are shown in their own window
along with the description of the gas type and measurement units. The current gas value for each
sensor will be updated on the display once per second.

If the user does not operate any buttons for one minute, the screen-saver will activate showing a logo
which will drift around the display with the screen dimmed. Pressing any button will wake the device
from screen saver mode and display the main gas screen. If the device is connected to the charger or
to a PC via USB, the screen-saver will not activate but the screen will still dim as normal.
NOTE:
The screen-saver function is intended to extend the battery life and prevent screen burn-in.
During screen saver mode, gas values are still monitored as normal. Any gas alarm will wake the
display from screen saver immediately and the main gas display will be shown.
Battery status
The battery status icon is shown in the top right hand corner of the display. This icon gives a
representative indication of the power remaining in the batteries. As the batteries run down from full to
empty, the battery icon will be displayed in various states.

Battery near empty. Approx. 1 hour of operation remaining.
A reminder beep will sound periodically.
The device is powered from the mains charger. The icon
will be shown next to the battery icon.
The device is attached to and powered by a computer via
a USB cable. The USB symbol will be shown instead of
the battery icon.
NOTE:
Due to the nature of the battery type, the battery status icon may temporarily indicate a
capacity higher than the true remaining battery capacity upon switch-on. This effect is usually seen in
devices which have been switched off for an extended period of time. The true battery status will be
indicated within a few minutes of power-up.
