lb, kg, PC
Three arrow annunciators on the right side of the

mode. The top and middle arrows, labeled lb and
kg, show primary and secondary units, as
described below:
•
If the displayed weight is in pounds, the top
arrow (lb) is lit; if kilograms, the middle
arrow (kg) is lit.
•
If the primary unit of weight is pounds, the
middle (kg) arrow is lit for secondary units—
or, if the primary unit is kilograms, the top
(lb) arrow is lit for secondary units, unless the
secondary unit of weight is the same as the
primary unit.
•
If neither primary nor secondary units are
pounds or kilograms, the top arrow is used as
a primary units annunciator and the middle
a r r ow i s u s e d a s t h e s e c o n d a r y u n i t s

A set of replacement overlay decals is included in
the parts kit for units other than pounds and
