The top of the page will display the date with the tide station below.
The top of the chart will show a 24-hour block of local time (LCL)
for your position, with the reported station time (STA) appearing at the
bottom. Daylight (light bar) and night (dark bar) will show across the time
scale, with the time progressing from left to right. (Local time scales and
sunrise/sunset info may not be available for a few stations). The solid, light
vertical lines are in 4-hour increments, with the light, dotted vertical lined
in 1-hour increments. A dark vertical line (with arrows at the ends of the
line) will indicate the time of day when using current date and will intersect
the tide graph to show their relation.
The tide curve will show as a shaded area, with higher tides being taller and
lower tides shorter. The dark horizontal line (with arrows at the ends of
the line) will indicate the current tide height. The ﬁ gure to the left of the
line will show the current tide level in feet. The Mean Lower Low Water
(MLLW) will appear as a solid vertical line near the bottom of the chart
(This line will only appear if the tide ranges to the zero value or below).
The top and bottom numbers to the left of the chart, ‘LCL and ‘STA’ indicate
the maximum/minimum levels, respectively. The four data ﬁ elds below the
chart, indicate event times and levels at which the tide changes starting in
the upper left ﬁ eld, going downward, then to the upper right and down

Hunt and Fish —
The Hunt and Fish Page displays data for Good and Best
times for hunting and ﬁ shing at the selected location. There is also a Rating
(excellent, good, normal, poor) displayed, that will reﬂ ect the productivity of
the day. You may display this information for your current location or you
can use the Map or Points Menu to select a location. To display the location
options, press ENTER with Location ﬁ eld highlighted. You can also use the
current date and time or enter a date and time of your choice.
The MapSource Info Page displays a list of the MapSource data stored in the
unit and description of the highlighted list item. You can choose to ‘Show’ the
data on the map, by placing a checkmark in the ‘Show’ Box. To select/deselect a
box, place the highlight over the MapSource Item then press ENTER.
The System Info Page will show your software version number and the unit
The Setup Menu is arranged in an easy to use tab format. Each tab (General,
Time, Units, Location, Alarms, Interface) contains the settings that will determine
how the unit functions. To select a tab, the highlight must be on the tab name
then use the ROCKER Key (right/left) to scroll through the tabs. To select a data
ﬁ eld on a tab, user the ROCKER Key (up/down) to highlight the selection then

Setup Menu — ‘General’ Tab
The ‘General’ Tab contains settings for the Receiver Mode, WAAS, Backlight
Time Out, and Beeper. To change a setting, highlight the ﬁ eld then press ENTER.
Make your selection then press ENTER to activate the selection.Mode —
The Mode selections are ‘Normal’, ‘Battery Saver’ and ‘Simulator’.
This is the default mode set from the factory. Use this setting
for best performance.
‘Battery Saver’ —
When ‘Battery Saver’ is selected, the receiver is optimized to
save battery power. When in the Battery Saver mode you may experience
slower screen updates, but should notice a signiﬁ cant increase in battery
life. While in Battery Saver mode, the unit will not receive WAAS satellite
When in ‘Simulator’ mode the GPS receiver is turned off and
the unit simulates satellite reception. Use the Simulator mode when the
unit is indoors and you wish to practice with the unit.
WAAS is an acronym for “Wide Area Augmentation System”. You
can use the WAAS capability of the GPS 76 to increase the accuracy to
approximately 3 meters. When enabled the GPS receiver searches for a WAAS
satellite, then receives data that will help correct differentials in the GPS
signal. When the unit is using WAAS data, a “D” will be displayed in the
Satellite Strength Indicators on the GPS Information Page, and the receiver
status will indicate a 2D or 3D Differential Location.
Currently the WAAS system is not fully operational and there are only two
satellites in place, one over the Paciﬁ c Ocean and one over the Atlantic Ocean.
You must have a clear unobstructed view of the sky for the GPS 76 to be
able to receive a WAAS signal, even then, at times it may not be possible to
receive a WAAS signal.
For more information on the WAAS system visit the Federal Aviation Adminis-
tration website at (gps.faa.gov).
