Command link multifunction meters

Command link multifunction meters have 6
kinds of meter units; tachometer unit (square
or round types), speedometer unit (square
type), speed & fuel meter unit (square or
round types), and fuel management meter
(square type). The indicator system is slightly
different between the round and square types.
Check the model and type of your unit careful-
ly. This manual describes mainly the warning
indicators. For more details on setting meters
or changing indicator systems, see the at-
tached operation manual.
