Notes about structure and electric circuit design
1. Suggest using non-magnetic screws, when mounting the scanner. Magnetic screws can cause
element/mirror neutral position to change.
2. It is recommended to use a thread locking method, such as a Nylok patch.
3. Do not place magnetic material (e.g. dynamic speakers, ringers, vibrators, inductors, metal parts)
within 1 inch of the scanner chassis. Evaluate placement of all magnetic or ferrous material during
system layout to determine if 1 inch is sufficient.
4. Leave sufficient space to accommodate the maximum size of the scanner.
5. Read section “1-2 Electrical interface/Pin assignment”, carefully to learn about the electrical interface
design.
