Bio-Rad Personal Molecular Imager™ (PMI™) System - Manual (Page 14)

Screen Eraser
The screen eraser has no minimum clearance requirement and may even be wall mounted,
using the mounting holes located in the unit's back plate.
All screen erasers must be plugged into a grounded electrical outlet
Sample Exposure Cassettes
The exposure cassettes do not require any power and can be placed in any convenient
location where radioactive samples are normally handled. If desired, the exposure peripherals
can be stacked or placed directly on the top or under the laser scanner to conserve bench
space.
3.1.2 AC Power Requirements
The scanner and all powered peripherals including the host computer should be connected
to a stable grounded power outlet on a circuit free of electrical noise. In addition, a high
quality electrical surge suppressor/line filter with a 10 A or higher rating should be used to
avoid damage from AC fluctuations. Only a grounded 3-pin power cord should be used to
connect power.
The scanner is designed for input voltages of 100–240 VAC at 50–60 Hz, and requires no
voltage setting or fuse change before operation.
The screen eraser is configured for 100–120 VAC, 50–60 Hz or 200–240 VAC, 50–60 Hz
operation. Please ensure that your eraser is configured to the appropriate voltage and fuse
settings before operation by checking the identification and settings label next to the power
input.
The external laser module must be configured for the proper voltage/current settings. This
should be done by qualified Bio-Rad Service personnel only, as damage could result if the
settings are incorrect.
If the power setting on the eraser or external laser module is incorrect, please contact your
local Bio-Rad representative
3.1.3 Host Computer Recommendations
The scanner is capable of producing large image files of high resolution; these can be up to
120 megabytes in size. To easily manipulate such large files, a powerful computer is
required. The host computer MUST meet or exceed the specifications detailed in Table 3.1
below.
Table 3.1 Host computer specifications
It is recommended to have a storage device for large image files, such as a second hard
drive or CDRW connected to your CPU.
