Deep Water—sets an alarm to sound when the depth is  
greater than the specified value.  
When the unit is receiving a DGPS signal, the SNR (Signal to  
Noise Ratio) and Distance fields contain data. The SNR range  
is 0dB to 30dB, with 30dB being the best. The Distance field  
may or may not show data, depending upon the signal being  
broadcast from the DGPS site.

Settings  
Acquiring Satellites—The receiver is looking for, and  
collecting, data from satellites visible at the last known or  
initialized position, but has not collected enough data to calculate  
a fix.  
Using the Celestial Tab  
The Celestial tab shows information about sunrise, sunset, moonrise,  
moonset, the moon phase, and the approximate sky view location of  
the sun and moon. By default, the unit shows celestial information  
for the present date and time.  
2D Navigation—At least three satellites with good geometry  
have been acquired and a two-dimensional position fix (latitude  
and longitude) is being calculated.  
From any Main page, press Menu twice and highlight Celes.  
To select a date and time for which to view celestial information,  
select the date or time field and enter text as described on  
page 2.  
3D Navigation—At least four satellites with good geometry  
have been acquired and your position is now being calculated in  
latitude, longitude and altitude.  
If your orientation is set to North Up and you want to quickly  
switch to Track Up while viewing the Celestial screen, press  
Menu and select Track Up.  
Poor Satellite Reception—The receiver is no longer tracking  
enough satellites for a 2D or 3D fix.  
Using the GPS Tab  
The GPS tab displays GPS satellite positions and signal strength  
bars.  
Receiver Not Usable—The receiver is unusable, possibly due  
to interference or abnormal satellite conditions. Turn the unit off  
and back on to reset.  
Simulating Navigation—The receiver is in simulator mode  
From any Main page, press Menu twice and highlight GPS.  
(page 23).  
Receiver status is indicated by the bar across the top of the screen.  
GPS accuracy information is indicated along the bottom of the  
screen.  
Looking For Satellites  
AutoLocate®—The receiver does not know your previous  
location. This process can take up to five minutes.  
Accuracy—indicates the approximate accuracy of the unit.  
DGPS Rcvr—indicates the status of the DGPS receiver  
(page 16).

Settings  
DOP (Dilution of Precision)—displays DOP, which is an  
indication of satellite geometry quality measured on a scale of  
one to ten. Lower numbers indicate higher quality signals.  
You can manually enter your altitude when in 2D navigation  
or simulator mode. Any altitude entered will be automatically  
calculated when the unit is in 3D navigation mode.  
DGPS SNR—displays the SNR when the unit is receiving a  
DGPS signal. The SNR range is 0dB to 30dB, with 30dB being  
the best.  
To set 2D altitude:  
1. From any Main page, press Menu twice and highlight GPS.  
2. Press Menu, and select 2D Altitude.  
WAAS (Wide Area Augmentation System) can provide more-  
accurate GPS position information in North America. However,  
when using WAAS, the device takes longer to acquire satellites.  
Using the Tide Tab  
From any Main page, press Menu twice and highlight Tide.  
The Tide tab shows a chart that displays tide station information  
in a 24 hour span, starting at midnight station time. You can select  
different dates.  
To disable WAAS:  
1. From any Main page, press Menu twice and highlight GPS.  
2. Press Menu, and select Disable WAAS.  
When your unit is turned on, it starts the search for your location  
based on where you were when it was turned off. AutoLocate is used  
by the GPS 152H to find your location when the unit does not know  
your previous location.  
To use AutoLocate to find your location:  
1. From any Main page, press Menu twice and highlight GPS.  
2. Press Menu, and select AutoLocate.

1. From any Main page, press Menu twice and highlight Tide.  
The top of the screen displays the tide station. The top of the chart  
shows a 24-hour block of local time (LCL) for your position, with  
the reported station time (STA) appearing at the bottom. The solid,  
light vertical lines are in 4-hour increments, and the light, dotted  
vertical lines are in 1-hour increments. A dark, vertical line indicates  
the current time.  
2. Press Menu, and select Nearest Tide Station. The name of the  
nearest tide station appears along the top of the screen.  
Note: You must be within 100 nautical miles of a tide station to  
use this feature.

Cleaning the Screen  
The lens on the screen is coated with a special anti-reflective coating  
that is sensitive to skin oils, waxes, and abrasive cleaners. Cleaners  
containing ammonia, alcohol, abrasives, or anti-grease detergents  
will harm the anti-reflective coating. It is important to clean the lens  
using an eyeglass lens cleaner (that is specified as safe for anti-  
reflective coatings) and a clean, lint-free cloth.  
If you are connected to COM2 for sonar NMEA input, the unit  
interface must be set to GARMIN DGPS, Other DGPS (4800  
only), or NMEA In/NMEA Out. If connecting to COM1, the unit  
must be set to NMEA In/NMEA Out (see page 15).
