Low battery alarm
When the battery charge drops near the lower limit, the Eagle displays the
following screen (BAT flashes). For alkaline batteries, you have
approximately 3 hours of use remaining; for Ni-Cd batteries you have
approximately 15 minutes of use remaining.
When the battery voltage drops to the minimum limit, the following screen
displays, the alarm lights are on continuously, and the buzzer sounds a steady
tone. The Eagle is not operational as a gas monitoring device when this
screen displays.
NOTE: If you are using the optional data logging accessory and the Eagle
goes into Low Battery ALARM, shut off the Eagle in order to save
the current data logging session.

occurs, the Eagle alerts you with audible and visual alarms.
If a sensor fails during start-up or normal operation:
