Determining if the Unit is Operational

When power is applied to the NCR 7870 Scanner/Scale, it
automatically performs Level 0 Diagnostics to check various
components.

NCR 7870-1000 and 3000 Scanners

After passing Level 0 diagnostics the Status indicator flashes green, a
tone sounds, then the Status indicator turns red. The NCR 7870 is now
operational.

NCR 7875-2000, 4000, and 4500 Scanner/Scales

After passing Level 0 diagnostics the NCR 7870 runs scale diagnostics.
During this time, all segments on the integrated or remote display are
turned ON so the operator can verify the display works correctly.
Then the display reads Ready 0.000 kg (Ready 0.00 lb). The Status
Indicator flashes red for five seconds, then the Status indicator flashes
green momentarily, a tone sounds, and the Status indictor turns red.
The NCR 7870 is now operational.

If the NCR 7870 Does Not Pass Level O Diagnostics

If an error occurs during Level 0 diagnostics, the integrated or remote
display (if the unit has one) displays an error code, and if enabled, the
NCR 7870 emits an audible description of the error and what action to
take. There may be some simple steps you can take to correct the
problem. See Chapter 8: Troubleshooting. If you cannot correct the
problem, contact NCR for warranty information.
