Key Functions
The Count Hold key will start or stop the computation of dis-
tance pulses. When in Count Hold,
CH
will be displayed in
D-2 and the RAC will not accumulate any distance. If speed is
also being displayed, it will continue as CH
does not
stop the
computation of vehicle speed. When released, CH in D-2 will
go out and distance computation will resume.
Display Hold will stop the display from updating while the
RAC will continue to accumulate distance internally. When
in Display Hold,
DH
will be displayed in D-2. If speed is also
being displayed, it will continue as DH
does not
freeze the
speed display. Note: You cannot put the RAC in both Count
Hold and Display Hold at the same time. Count Hold will take
precedence over Display Hold.
The Unit key allows you to select the desired unit of measure-
ment. This can be selected/changed while moving or at rest.
When pressed, the distance will cycle from total feet to miles to
kilometers/meters. The LEDs to the left of D-1 indicate which
unit is currently being used.
The Speed key allows you to turn on or off the display of speed
(mph or kph) in D-2. The display of speed is not interrupted by
either the Count Hold or Display Hold keys.
