CCS Technical Documentation
Is proximity optics and proximity rubber OK (visual check)? If not, replace optics. Check
calibration conditions and repeat calibration.
FAULT OVER LIMIT FAIL (0x10)
This error occurs in fault detection threshold calibration, if self-monitoring signal is
higher than each fault detection threshold. There are two reasons, that could cause this
failure:
Detection calibration is done without the calibration target or the target was too far
from the phone.
Fault calibration was done with the calibration target.
Check calibration conditions and repeat calibration.
GAIN MAX LIMIT FAIL (0x0B)
Gain value has reached its maximum limit, and there are no detections. This means, that
path from tx to rx is broken. Most probable is, that the failure is on the LG4. Figure 5
GAIN MAX LIMIT FAIL troubleshooting presents troubleshooting diagram for this failure.
