Sun and Moon —
The Sun and Moon Page displays data for Sunrise/Sunset,
Moonrise/Moonset, and the approximate location of the Sun and Moon on a
skyview. The moon phase will display the current visible portion of the moon
in a light color. 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
press ENTER. To restore the GPSMAP 76 to the factory settings for items on the
tab, press MENU and with ‘Restore Defaults’ highlighted press ENTER.
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 —

‘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
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 GPSMAP 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 GPSMAP 76 to
be able to receive a WAAS signal, even then, at times it may not be possible
to receive a WAAS signal. WASS satellites are not received in Battery Saver
For more information on the WAAS system visit the Federal Aviation Adminis-
tration website at (gps.faa.gov).
‘Backlight Timeout’ —
Sets the time that the Backlight will remain on once
activated. The options are ‘Stays On’, ‘15 Seconds’, ‘30 Seconds’, ‘1 Minute’
and ‘2 Minutes’.
This setting determines when the Beeper is used. The options are
‘Key and Message’, ‘Message Only’, and ‘Off ’.

time in a 12 or 24 hour format.
‘Time Zone’ —
The ‘Time Zone’ setting has nine options, Atlantic, Eastern,
Central, Mountain, Paciﬁ c, Alaska, Hawaii, Samoa, and Other. If you choose
‘Other’ a new ﬁ eld “UTC Offset” will be displayed. Enter the correct offset for
your Time Zone. You can ﬁ nd a chart with UTC Offsets in Appendix C.
‘Daylight Savings Time’ —
Has three options, ‘Yes’, ‘No’, and ‘Auto’. If
you select ‘Auto’ the unit will automatically determine when Daylight Savings
Time should be displayed. If you select ‘Yes’ Daylight Savings Time for the
current location will be displayed. If you select ‘No’, Daylight Savings Time
will not be displayed. If you have ‘Other’ selected in the ‘Time Zone’ ﬁ eld, this
option will not be available and Daylight Savings Time will be off.
‘Current Date’ —
This ﬁ eld shows the current date as determined by the unit,
it is not accessible by the user.

Setup Menu — ‘Units’ Tab
The ‘Units’ Tab contains settings for Elevation, Depth, Distance and Speed,
Temperature, Direction Display, and Speed Filter. These settings are used in
related ﬁ elds throughout the unit.‘Elevation’ —
Can be set to show in ‘Feet’ or ‘Meters’.
Can be set to display in ‘Feet’, ‘Fathoms’ and ‘Meters’. The
GPSMAP 76 cannot measure depth on its own. The depth input has to come
from a NMEA device providing the “DPT” sentence.
‘Distance and Speed’ —
Can be set to ‘Nautical’, ‘Statute’ or ‘Metric’.
Can be set to ‘Fahrenheit’ or ‘Celsius’.
‘Direction Display’ —
Can be set to ‘Numeric Degrees’ or ‘Cardinal Letters’.
The setting will be used in all ﬁ elds that relate to direction throughout the
‘Speed Filter’ —
Can be set to ‘Auto’ or a ‘User’ deﬁ ned setting. If ‘User’ is
selected, a Seconds ﬁ eld will be displayed. To enter a ‘User’ deﬁ ned setting,
highlight the Seconds ﬁ eld then press ENTER. When ﬁ nished, press ENTER
to save the entry. When using a ‘User’ deﬁ ned setting, the unit will average
the speed and heading at the rate speciﬁ ed in the time setting.
Setup Menu — ‘Location’ Tab
The ‘Location’ Tab contains the settings for ‘Location Format’, ‘Map Datum’,
‘North Reference’ and ‘Magnetic Variation’. The settings are used in related ﬁ elds
throughout the unit.‘Location Format’ —
There are 28 different formats to choose from. See the
sidebar for a list of the formats. You should not need to change the format
unless you are using a chart or paper map for navigation. If so, ﬁ nd the
format that most closely matches your chart or map. hddd.ddddd°
