Addendum to NAVMAN’s Tracker 500/500i Owner’s Manual
New feature – Centre on boat /
follow boat.
Once the -ctr- key combination (simultaneous press
of zoom-in and zoom-out) is pressed the track plot
screen will follow the boat until the mode is
“unlocked”. Unlocking is by panning the track plot
screen (when the cursor gets to the edge of the
screen), or zooming in until the boat moves outside
the central area of the screen. Activation of the
centre on boat mode feature is indicated by a small
hollow boat diamond between the speed and
heading on the bottom line of the track area.
Note: This feature will be activated by default on
power up and may be activated from anywhere,
not only the track screen, compared with the earlier
centre feature noted on P9 of the manual. The unit
will switch to the track plot screen whenever the -
ctr- key combination is pressed.
New feature – 3 Configurable alarms
The highway width is no longer changed in the setup
menu as indicated on P33 of the manual. This
setting has been replaced with an “ALARM” menu
with settings for 3 alarms.
1) Highway XTE alarm.
When the setting “HIGHWAY” is turned on, the XTE
(Cross track error) is continually monitored while
navigating to a waypoint. If the boat moves outside
the selected highway screen road width, an alarm
prompt will be shown, and the buzzer will sound.
Notes: 1) The alarm will reactivate every time the
boat moves inside the highway screen road width,
then strays outside it again. 2) The highway screen
does not have to be showing for the alarm to
activate.
2) 1 MINUTE alarm
When the setting “1 MINUTE” is turned on, the TTG
(Time to go) is continually monitored while
navigating to a waypoint (during navigation of a
route, the setting is active for each waypoint in the
route). The first time that the TTG drops below 1
minute, an alarm prompt will be shown, and the
buzzer will sound.
Note: The alarm will not reactivate if the TTG raises
above 1 minute, then drops below 1 minute again.
3) Anchor drag alarm.
When the setting “ANCHOR” is turned on, the
change in position is continually monitored. If the
boat moves a distance greater than that set by
“ANCHOR 0.xx” from the boat’s position when
“ANCHOR SET >” was activated, an alarm prompt
will be shown, and the buzzer will sound.
Notes: 1) The alarm will reactivate every time the
boat moves inside the anchor circle, then strays
outside it again. 2) Without DGPS (Differential
GPS), selective availability may cause the reported
position to deviate by up to 900 feet. This will trip
the anchor alarm, the distance of “ANCHOR 0.xx”
may need to be increased.
New feature - Distance log.
The position screen as pictured on P15 of the
manual now also displays distance travelled since
last cleared. This works by measuring a succession
of straight lines (similar to the track drawing). This
means that it will not be highly accurate if you drive
around in small circles (e.g. 600ft) all day. However,
if you forget to turn it on at the start of the journey,
you will still get a good approximation of the distance
from the position where the unit last had a fix. The
distance units setting as indicated on P34 of the
manual has been replaced by a distance menu,
which allows clearing of the distance log and setting
of the distance units.
New feature – User configurable
waypoint display.
New options have been added to enhance the
display of waypoints on the track screen.
On the waypoint edit screen (see P25 of the
manual), two extra settings have been added.
“NAME | ON/OFF”, “SYMBOL | ON/OFF”. By
default, when a new waypoint is created, only the
symbol will be shown on the track screen. Turning
the name display on will cause the waypoint’s name
to be displayed to the right of the waypoint on the
track screen. Turning the symbol display off will
prevent the waypoint from being shown on the track
screen.
Notes: 1) Turning the symbol off does not delete
the waypoint. The waypoint can simply be selected
from the waypoint list and the symbol turned back
on again. 2) You cannot have the waypoint name
turned on, and the waypoint symbol turned off.
On the main waypoint menu (see P22 of the
manual), two extra settings have been added.
“NAMES | ALL/NONE/SEL.”, “SYMBOLS | ALL/
NONE/SEL.” When SEL. (short for SELECTED) is
chosen the name/symbol will be displayed
according to each individual waypoint setting. When
ALL is chosen, the name/symbol will be displayed
regardless of each waypoint setting. When NONE
is chosen, the name/symbol will not be displayed
regardless of each waypoint setting.
Note: You cannot have the waypoint names turned
on, and the waypoint symbols turned off.
New feature – Goto key.
Holding the zoom-in key, while any screen is
showing, will take you immediately to the GO, TO
WAYPOINT, TO MARK, ALONG ROUTE screen
as shown on P21 of the manual.
Note: If you are already navigating to a waypoint,
an option will first be presented asking whether you
want to cancel that navigation first.
