External Mouse Device
Included with each shipment of a DNA Engine Tetrad 2 thermal cycler is an externally
attachable mouse, which should be attached prior to power up of the
DNA Engine Tetrad 2 cycler. Usage of the mouse is required to access full function-
ality of the programming software. Underneath the front lip of the DNA Engine Tetrad
2 cycler are two connection ports (see figure 2-4). The mouse should be connected
to the USB A port.To ensure complete compliance with FCC and EMC requirements,
only a mouse with a ferrite core should be used with the DNA Engine Tetrad 2 instru-
ment.
To connect the mouse, please follow these steps:
1. Verify that the DNA Engine Tetrad 2 cycler is off. Wait for 10 seconds to ensure
that all fans have stopped rotating.
2. Grasping the sides of the DNA Engine Tetrad 2 cycler, tilt the instrument back so
that the underside of the lip is visible.
3. Insert the mouse into the USB A port and push the connector into place.
4. Tip the DNA Engine Tetrad 2 cycler back down and power up the system.
Environmental Requirements
Ensure that the area where the DNA Engine Tetrad 2 cycler is installed meets the
following conditions, for reasons of safety and performance:
•
Nonexplosive environment
•
Normal air pressure (altitude below 2000 m)
•
Ambient temperature 5–31°C
•
Relative humidity of 10–90% (noncondensing)
•
Unobstructed access to air that is 31°C or cooler (see below)
•
Protection from excessive heat and accidental spills. (Do not place the
DNA Engine Tetrad 2 cycler near such heat sources as radiators, and protect it from
danger of having water or other fluids splashed on it, which can cause shorting of its
electrical circuits.)
