Loose Optical Cable
Following intermittent problems may occur:
• Baseline (drift/noise)
• No peaks
• Lamp intensity test fails
• WL verification fails
• Other effects related to the optics
In such a case check the cable connection between optical unit (under the
cover, see Figure 33 on page 115) and the main board. If this is loose,
intermittent or constant effects can be seen.
