Emergency Off Switch (Emo); Laser Safety Warnings - Labcyte Echo 520 User Manual

Emergency Off switch (EMO)

The Echo liquid handler includes two Emergency Off
switches, also known as EMO (Emergency Motion Off)
switches. They are located on the front and rear of the unit
and are prominently labeled "EMERGENCY OFF." See
"Emergency Off label," on the next page for switch
location.
See "Emergency Off switch" on page 3-11 for a detailed explanation of
what the Emergency Off switch turns off, when to use it, how to use it, and
how to resume normal Echo liquid handler operation after using it.

Laser safety warnings

The Echo liquid handler is a Class I laser instrument that can house up to
three optional laser-based barcode scanners.
When operated as specified in this manual, the Echo liquid handler does
not expose the operator to laser light. Nevertheless, during a barcode scan,
the Class II diode lasers (with maximum power up to 1.0 mW at 650 nm)
can be visible from the interior of the unit. The barcode scanners are not
interlocked; therefore, if the Echo liquid handler is operated with the covers
off, the operator may be exposed to a Class II laser light hazard. Do not
operate the Echo liquid handler if its covers have been removed.
