RANGE:
The RANGE can be set to suit the circumstances e.g. if a water depth of 35 m is indicated, the
50m range will give a better resolution and accuracy than the 200 m range. The range can be
altered in the same way as the gain, except that here, pressing the RANGE key V will decrease
the range and pressing the RANGE key W will increase the range. There are 6 ranges to choose
from, 10, 20, 50, 200, 500 and 2000 m (or the equivalent in fathoms or feet). Selecting the unit of
measurement is described in chapter 4.5.2.
Increasing the range to more than 2000 m scale an "A" will appear together with the 200 m scale.
"A" indicates the selection of the automaticc mode. When the water depth decreases the range will
at depth less than 50 m switch automatically in the 50 m range scale, if the depth increases, the
200 m range will be selected. Pressing in the automatic mode the range keys, manual control is
activated.
NOTE: When DBS is used, the ranges 0-10 m; 0-20 m are not available, only 0-50 m.
DIM:
The display backlighting can be set in 10 steps to suit the ambient light. To increase the display
backlighting, press the DIM key V. To decrease the display backlighting, press the DIM key W
(see NOTE below).
All other parameters and settings are altered within so called MENUS, as described in chapters
