1.3 Speed key functions

The following flow chart shows the speed key functions.

Speed

The speed display can be either knots (Kts), miles per hour (Mph), or
kilometres per hour (Kph).

Trip distance

Trip is the distance covered between power on and power off. This can
be nautical miles (NM), kilometres (KM), or statute miles (SM).

Resetting Trip Distance

Press and hold the speed key until the trip distance is zeroed - distance
flashes after 1 second and during the resetting process.

Ships log

When this value exceeds 999 NM, SM, or KM, the Bidata displays the
log as thousands (th) and, after 3 seconds, hundreds, tens, and units. For
example, 1525 nm would be displayed as 1th then 525.
