out of range and requires attention.

requires immediate attention.
These status indicator lights are also provided on the back panel. For more
information, see “Status indicator lights” on page 3-9.
LCD screen: The LCD screen on the front of the Echo liquid handler
reports what the Echo liquid handler is doing or what operator action is
required. This display is also provided on the back panel. For more
information, see “LCD screen” on page 3-11.

mergency Motion Off) switch shuts down all
mechanical Echo liquid handler activity. This switch is also available on the
rear panel.
