Two LED alarm-lights are located

various display options. It beeps once during the startup
sequence. Refer to Section 3.1 for alarm indications.

malfunctions, and as an indicator during normal use of
the various modes of the CMS-4. It vibrates briefly
during the startup sequence.

A CR2450, 3.0-volt lithium
coin battery powers the CMS-4. The battery icon in the
upper right of the LCD shows remaining battery life.
When the CMS-4 detects a low battery voltage, a low
battery warning is activated. When battery power is too
low for Measuring Mode, the CMS-4 sounds a dead
battery alarm. (Gas reading disappears,
