Is the SP78-200 BCR configuration correct?
To restore the factory default mode:
1) Disconnect the BCR from the instrument.
2) Reconnect the BCR to the instrument.
3) Scan the default configuration bar codes.
Does the SP78-200 BCR wavelength of light match the bar code?
The BCR will not read bar codes that are designed to be secure (black
on black.) The optical signal returning from the bar code is not adequate
for measuring the bars and spaces.

The BCR will operate when held at an angle of 5° to 45°. The
optimum operating angle is from 10° to 30°.
