opposite of the geophone.

2.4.4 Placing the LIU in the Field

The LIU is part of the backhaul configuration. See “3. Backhaul” on page 26 for more

information.

2.5 WRU Anchor Plate

This WRU Anchor Plate (10-0028) is designed to reduce downtime due to tipped units and to

reduce losing units as a result of theft. The shape maintains the WRU stacking ability while

providing three solid anchor points. Constructed of light-weight and durable thermoplastic

polyurethane, it attaches to the bottom of the WRU with minimal effort while maintaining the

integrity of the WRU seal.

The anchor plate is compatible with the temperature range of the WRU which is -40°C to

+75°C (-40°F to +167°F).

NOTE

See “D. LED Indicators” on page 163 for an explanation of the LED status and

error conditions.

If a WRU self test fails, the WRU will continue to the next test.

Skip a self-test by tipping the WRU geophone down and then returning it to the

upright position (flat on the ground).
