TIMEWISE 798A

Nevertheless, as is the case for the normal calculated time, the non-truncated individual
times for each CAST section are added together to make up the total auxiliary calculated
time. This is the method used by most rallymasters when computing official leg times.
The “Delta”
Counters
When the “ ” (the Greek letter “delta”) position of the
T I M E – –O D O
switch is selected,
you can see the
A m o u n t o f Ch a n g e
, or delta adjustment, applied to the main odometer or
the calculated time. There are two delta counters, one for the main odometer and one for the
calculated time. The position of the rotary switch dictates which delta counter is displayed.
When
Odometer
or
Adjust ORM
is selected on the rotary switch, the odometer delta
counter can be displayed, showing the sum total of adjustments made to the odometer. The
total includes all adjustments made using the
Adjust ORM
,
Odometer
, and
Odo & Time
functions. Note: The odometer delta counter does not include
LAST CAST
adjustments,
except when using the discretionary
Intelli-Fix™
feature (option 10).
When
Calc
Time
is selected on the rotary switch, the calculated time delta counter can be
displayed, showing the sum total of adjustments you’ve made to the calculated time using
the
Calc Time
function. IMPORTANT: Changes to the calculated time that result from use
of the
Adjust ORM
,
Odo & Time
, or the
LAST CAST
functions are not included.
The delta counters can show a value from –99.999 to 999.999 when displaying distance, or
–59.99.9 to 5:59.99.9 when displaying time. When a parameter exceeds this range, the
displayed digits will still be correct and the value will retain the correct sign. (Note that time
values greater than 5:59.99.9 roll over to –[6:]00.00.0).
The delta counters can be independently reset to zero. The odometer delta counter is reset by
selecting
RESET
on the
RESET–SHIFT
switch when
Odometer
or
Adjust ORM
is selected
on the rotary switch. The calculated time delta counter is reset by selecting
RESET
when
Calc
Time
is selected on the rotary switch.
CHANGING
THE DISPLAY
BRIGHTNESS
When the 798A is powered up, the displays illuminate at their brightest setting.
The display brightness can be adjusted to fit ambient lighting conditions. When the special
function position is chosen on the rotary switch, activating the “+ / –”
.10
toggle switch
changes the intensity of the displays on the main computer. If you depress
SHIFT
while
making the change, the driver’s display brightness is adjusted. Beneath the “+ / –”
.10
toggle
switch are the designations “
Brightness
” and “
Remote Brightness
”. The displays become
dimmer when you select the “–” position; they get brighter when you select the “+” position
The
AUXILIARY
display indicates the brightness level selected for the main and remote
displays. There are 32 levels for each display group. The two rightmost digits show the
main display setting, whereas the two leftmost digits show the driver’s display setting.
All displays (including those in the driver’s module) turn off when the main computer is
dimmed below level 1. All measurements continue while the displays are off. The displays
will re-illuminate with the activation of any switch. Using a “+ / –” toggle to re-illuminate
the displays will not alter a parameter regardless of the rotary switch position.
Note: After 16 minutes of inactivity, the displays automatically turn off. Use any switch, or
drive the vehicle, to re-illuminate the displays. The “+ / –” toggle switches will not alter a
value when exiting this automatic power saving mode. To prevent the displays from turning
off when the 798A is idle, place the rotary switch in its
Next Speed
position.
