5.4. Battery Indicator
The EchoView's internal battery is designed to provide power for up to 10 days. When the battery
gets low, the EchoView beeps once per minute and the battery icon is empty. See page 35 for the
replacement procedure. It is recommended that the battery be changed immediately, to minimize
potential downtime. When the battery is almost completely depleted, the LCD displays "Power off,"
and the LED and buzzer alarms activate once per second. The battery icon also blinks on and off.
The low battery alarm continues until the battery runs out. Then the unit shuts down automatically.
Battery power is indicated with an icon in the lower right corner of the screen, below the wireless
communication indicator and buzzer icon:
Battery charge is shown from empty to full:
Note: For a fixed-system application, an external power source, the RAE PowerPak, can be used
as a substitute for the internal battery. Only remove the external battery adapter in non-hazardous
locations.
5.5. Buzzer (Audible Alarm) Off Indicator
The EchoView's buzzer (audible alarm) can be turned off, so the LED visible alarms flash but there
is no sound when in alarm. The icon on the main screen indicates its state.
