Motion Sensors, Inclinometers and
Longer Interconnect Cables
This valuable accessory unit must be mounted correctly to obtain any benefit from it:
a) Select a mounting location that is dry and vibration free
b) The selected location should be as close to the sonar hoist unit as possible
c) Mount the unit level (only compensating for normal vessel trim)
d) Line the unit up "fore and aft" accurately
e) Mount the unit "right side up" only
If a longer interconnect cable assembly is required, the following options are available:
Part number
Description
MS1-CBL-15M 15 meter signal cable assembly
MS1-CBL-30M 30 meter signal cable assembly
MS1-CBL-50M 50 meter signal cable assembly
Note:
The MS100 compensates for any vessel pitching and rolling at sea. To properly set itself the
motion sensor must be powered up while the vessel is in a stable condition. This step is easi-
er to accomplish at the dock. Please get in the habit of powering up the entire CH270 system
prior to departing from the dock. This one easy step will ensure proper operation of the
MS100 and enhanced CH270 performance for the duration of the voyage.
Soundome Cover Removal and Replacement
To detach or replace the soundome cover assembly, remove the 8 stainless steel cross
head cap screws.
Once the soundome has been filled with oil, keep it in a vertical position to prevent any
internal seepage. If the soundome assembly has to be removed for repair or shipment, the oil
must always be removed.You may wish to retain the soundome packing material for future
use.
