OBS-5+ System

FIGURE 8-1. Internal components

OBS-5+ or pressure sensor malfunction.

• Open unit and inspect for: 1) broken sensor wires, and 2) loose pressure

sensor connector (FIGURE 8-1).

• Check sensor power by clicking

Survey and selecting all sensors; the

green LEDs should illuminate. If they do not, the sensor power circuit

may not be working.

• If the depth sensor reads high and does not change, it may need to be

cleaned (see Section 9.2, Pressure Sensor).

• If the sensors appear to be in working order, the digitizer or

microcontroller may be damaged. Such problems require factory service.
