3-7 Setup > Comms

Use this feature when the FISH 4500/4600 is connected to other Navman instruments through NavBus or any compatible NMEA instrument.

Press MENU once or more until the Setup menu is displayed, then select Comms:

NMEA Out

NMEA is generally used with third party instru- ments. Select to transmit NMEAsentences (see Appendix A - Specifications).

NMEA data

Use this to specify which NMEA sentences will

be transmitted (see Appendix A - Specifications and section 5-7 Data display, for information about how to display NMEA data).

NavBus

NavBus is the preferred method for connecting the FISH 4500/4600 to other Navman instru- ments. Select if the instruments are connected using NavBus.

NavBus Group

Use this when a group of Navman instruments are connected together using NavBus, to specify a group of instruments for backlighting, if required. Then, if the backlight setting on one instrument in the group is adjusted, the other instruments change automatically. Otherwise, select 0.

Press MENU once or more until the Setup menu is displayed, then select Calibrate:

The fuel options can be calibrated only whentheoptionalsin- gle or twin engine kit is installed on petrol/ gasoline engines.

Speed

Calibration may be required because different hull shapes have different flow characteristics. Obtain an accurate measurement of the boat’s speed from a GPS receiver; or by following another boat travelling at a known speed; or by making a timed run over a known distance.

Note: for accurate calibration:

The speed from a GPS receiver should be greater than 5 knots.

The speed from another paddlewheel trans- ducer should be between 5 and 20 knots.

Best results are achieved in calm conditions where there is minimal current (best at high or low tide).

Use the cursor keys to display the speed readout box, then increase or decrease the readout to match the independent speed value.

Speed Filter

Increase this setting to stabilise an erratic speed reading. Decrease to improve reading respon- siveness. The speed filter can be set from 0 to

30seconds.

Temperature

The factory settings should be sufficiently accurate for normal usage. To calibrate the temperature readout, first measure the water temperature with a thermometer known to be accurate.

Use the cursor keys to display the temperature readout box, then increase or decrease the value to match the measured temperature.The tempera- ture can be set from 32° to 99.9°F (0° to 37.7°C) with a resolution of 0.1° unit.

To change the units between °F (Fahrenheit) or °C (Celsius), see section 3-6 Setup > Units.

Temp filter

Increase this setting to stabilise an erratic tem- perature reading. Decrease to improve reading responsiveness. The temperature filter can be set from 0 to 30 seconds.
