Page 5: Repacking And Shipping
1.2 Repacking and Shipping If original packing materials are unavailable, the equipment should be packed with at least 80 mm of absorbing material. Do not use shredded fibers, paper wood, or wool, as these materials tend to get compacted during shipment and permit the instruments to move around inside the package. - Page 6 compagnies minières à buts lucratifs, les compagnies de construction et les organisations responsables pour le sauvetage et la lutte contre les incendies.

2 External connectors indicators and controls In figure 1, below, pictures of the HDR-160MHz are shown. All antennas in this series have the same basic layout, only that for the 750MHz, no-side handles are available. In the following a brief description of the unit is given, with reference to arrows and labels in figure 1. -
Page 8: Battery Mount
2.1 Battery mount In figure 2, below, a dummy battery as well as a normal battery is shown. They look similar but the dummy has a 4-pole fisher connector on the back. The dummy is used when the antenna is powered from an external 12V battery. Both of these units are mounted in the same way on the antenna, see below. -
Page 9: Cables
For this reason all MALA cables have ferrites attached to them as well as recommended routing. If you experience some ring-down, please first check your cable mounting, it has been the main cause of internal complaints, previous acceptable routings are no longer valid. -

ON/OFF-Switch Figure 6, ON/OFF-Switch 2.5 LED-indicators Three LED-indicators are mounted beneath the product label, see figure 7 below. The meaning of these indicators is as follows: DATA: Continuous flashing light means that the unit is working properly and ready for data collection, no proof of that a monitor is able to receive data, though. -

LED-Indicators Figure 7, led indicators. 2.6 Mounting of measuring wheels The several measuring wheels are available for the HDR-units. Each one of them has been designed to fit to the field-proven ruggedized connector housing on the back of the antennas. To connect a wheel, gently push the wheel connector into the connector housing and attach the secure-pin. -

Soil velocity: The operator must know this value, if hesitant please refer to tables available in MALA-literature. It does not matter for the actual data acquisition; the only risk is that not deep enough data is gathered. Normal values are 70-120m/us. - Page 16 Point interval: define the distance between every point of measurement, i.e. the distance between every trace. Default values, guarantees no data aliasing.
