Operation Manual
NOTE: The GYRO HDG bearing data becomes “XXX.X” and the buzzer sounds in
the following circumstances:
1. When no gyro signal is input.
2. When no power is applied to KSA-08A. Check the power supply line to KSA-08A
for power failure, disconnection, etc.
3. When initial setting of the gyro bearing is not completed.
In case at least one condition has been met, the bearing stabilized picture in relative
or true motion mode such as N UP RM (North Up Relative Motion), C UP (Course
Up Relative Motion) or N UP TM (North Up True Motion) will be reset to H UP RM
(Head Up Relative Motion) mode.

NOTE for NMEA sentences, VHW and VBW:
When the VHW sentence is selected, the Doppler Log or a speed log (Magnetic or
Mechanical) can be selected according to the talker device name included in the
sentence. When the VBW sentence is selected, only the Doppler LOG is selected.
