[CA] [CA11] B164 Settings with a C90W

[Jett Ward]

What should the default B164 Speed Offset setting be programmed on a C90W interfaced with a DSM370?
Select Speed Transducer... Auto
Frequency Calibration
Depth Offset... 1.4' (Trophy 2302)
Speed Offset... ??? (requires a percentage and 000% is not an option)
Temperature Offset... 0.0F

For the DSM, I currently have:
SONAR Interference Rejection... Auto
2nd Echo Interference Rejection... Off (Not sure what this is for or if it should be in Low)
Ping Rate Limit... 32 (the default setting)
Ping Enable... Enabled
