GX1600/GX1700
14.4 TIME OFFSET
From the factory the GX1600 and GX1700 shows GPS satellite time or UTC
time. A time offset is needed to show the local time in your area. The time
offset must be changed in order for the radio to display the current time in
your area. Refer to section “6.7 CHANGING THE GPS TIME” for setting.
14.5 TIME AREA
This selection allows the radio to show UTC time or local time with the offset.
Refer to section “6.8 CHANGING THE TIME AREA” for setting.
14.6 TIME DISPLAY
This selection allows the radio to setup to show time in 12-hour or 24-hour
format. Refer to section “6.9 CHANGING THE TIME DISPLAY” for setting.
14.7 MAGNETIC
This selection allows the GPS COG (Course Over Ground) to be selected
to show in “True” or “Magnetic”. Factory default is “True” however the COG
can be changed to “Magnetic”. Refer to section “6.10 CHANGING COG TO
TRUE OR MAGNETIC” for setting.
14.8 POSITION INPUT
This selection allows the latitude and longitude of your vessel to be manually
entered so a DSC distress or a position report call will contain position infor-
mation. This feature maybe useful when the GX1600 and GX1700 is located
in an area where GPS reception is limited. Refer to section “9.9 MANUAL
INPUTTING A GPS POSITION
(
LAT/LON
)
” for setting.
14.9 GPS SELECTION (GX1700)
This selection allows the GX1700 to:
a. use the internal GPS to compute and display position information
(default setting).
b. use the NMEA output of Standard Horizon GPS Antenna (Q7000619A)
to input position information into the GX1700 when the GPS reception
is limited, such as the ush mounting of the GX1700. Refer to page 15
for connections. This is a useful feature when the GX1700 is located in
an area where GPS reception is limited.
NOTE
When using an external GPS antenna or chart plotter to input
position data, turn off the GPS receiver, refer to section “14.1 UNIT
POWER (GX1700)”.
