This setting is essential for best sonar performance.
Adjust to fine tune the transducer frequency to ensure
maximum target strength. The transducer frequency is
displayed above FQ (e.g. 20.500 kHz). The optimum
frequency will vary slightly for each unit. The frequency
changes in discrete steps (e.g. 0.500 kHz steps for a 90
kHz
transducer).
Initially, set this to the frequency stenciled on the
transducer cable near the Transceiver Unit connections.
This setting is calibrated at the factory and may need
minor adjustment to compensate for transducer aging
or when the transducer shield is removed
(the factory
calibration is set with the shield installed)
