We encourage you to read through this manual and experiment using the
built-insimulator. ThiswillhelpyouquicklymasterthepoweroftheGPS50.
1.2 OPERATIONS
You may use your GPS 50 for both portable and fixed operations. The unit
may be operated from external AC power using a battery charger, external
5-40 volt DC power using the power/data cable or cigarette lighter adapter,
or using a battery pack.
HandheldOperation:
Forhandheldoperation,theGPS50is poweredbyaAAbatterypackwhich
should be filled with four high quality alkaline batteries commonly found at
retailstores. Arechargeablenicadbatterypackisalsoavailableforhandheld
operation.
In order to track GPS satellites, the unit must be situated with the antenna
pointed straight up and should not be blocked by objects or people (signal
receptionthroughthinfabricsuchascanvasmaybeadequatebutdegraded).
A lanyard is provided to prevent accidental dropping of your GPS 50.
(Connect the lanyard to the eyelet on the back of the unit.)
FixedMountOperation:
A universal mount is supplied for swivel or surface mount installation in a
boat. Theunitmaybeoperatedusingvehiclepowerthroughthepower/data
cable or it may be operated using the battery pack. While using vehicle
power, you may wish to leave the battery pack in the unit. In the event of
vehiclepowerfailure,theGPS50willautomaticallyswitchtobatterypower.

external antenna for an unobstructed view of the sky. This weather-proof
antennaincludes30feetoflow-lossantennacable. Theremoteantennahas
been constructed to thread onto a standard 1" antenna mount. Antenna
mounts,commonlyusedtoattachVHFradioantennasandLoran-Ccouplers,
are readily available from your local marine accessories dealer.

GETTING STARTED
2.1 FRONT PANEL
The front panel consists of a 20-key keypad and a LCD display which
includesthreelinesofinformationandvariousbanners. Boththedisplayand
keypad are illuminated for operating in darkness.
2.2 BANNERS
Information displayed on the LCD is commonly referred to as a “page”. A
pageconsistsofalphanumericinformationandbanners. Banners,illustrated
below, are used to indicate the type of page, navigation units, and data
displayed(seeAppendixB). Theyalsoindicatenavigationfixtype,satellite
tracking, and provide user prompting.

2.3 CURSOR AND FIELDS
Alphanumeric Field Cursor on
Confirmation Field
Numeric Field Cursor on Cyclic Field
The area of the page which is underlined is called thecursor. The cursor
maybemovedtolocationsonthepagecalledfieldswhichallowyoutoenter
data. You will encounter four types of fields.
·Numeric fields accept numbers. For example, you will enter a
waypoint's latitude in a numeric field.
·Alphanumericfieldsacceptnumbersaswellasletters. Forexample,
you will enter a waypoint's name in an alphanumeric field.
·Cyclicfieldsallowyoutoselectfromoneofseveralavailableoptions.
For example, you may select between DTK (desired track), BRG
(bearing to waypoint), or CTS (course to steer) using a cyclic field.
Cyclic fields are indicated on the display by the “MORE” banner.
·Confirmationfieldsallowyoutoindicateyourapproval. Forexample,
you will be asked to confirm that you want to delete a waypoint.
Confirmation fields always end with a “?” character.
2.4 KEYPAD OPERATION
The PWR/BRT key is a dual function key thatcontrols unit power
and panel backlighting.
When the unit is on, pressing the PWR/BRT key will turn on the
panelbacklighting. Pressing thePWR/BRTkey again willturn off
thebacklighting.
To turn the unit off, press and hold the PWR/BRT key for three
seconds until the display is blank.

Pressing the NAV key selects the Navigation Pages which allow
youtoviewnavigationinformationandperformplanningfunctions.
(See Sections 3.3 and 3.5 and Chapter 5.)
PressingtheWPTkeyselectstheWaypointPageswhichallowyou
tocreate,edit,delete,andrenamewaypoints. Inaddition,youmay

Pressing the RTE key selects the Route Pages which allow you to
edit, review, activate, and delete routes. (See Chapter 6.)
Pressing either of the arrow keys allows you to move the
cursor,scrollthroughinformation lists, and enterlettersof
thealphabet.
The alphanumeric keys allow you to enter letters and
numbers into the GPS 50.
Ifyouwanttoenteranumberinanumericfield,forinstance
“1”, simply press the 1 key. If you want to enter a letter in
an alphanumeric field, for example “A”, press the 1 key to
display B, then press the left arrow key once to select “A”
(you may also press the right arrow key three times to
display the “A”).
Pressing the CLR/MORE key erases information in the
cursor field. If the cursor is over a cyclic field, pressing the CLR/
MORE key will toggle through several available options.
Pressing the ENT key completes the process of data entry. If the
cursor is over a confirmation field, pressing the ENT key indicates
yourapproval.

2.5 ENTERING DATA
To enter data you must first move the cursor under the desired field by
pressing the right or left arrow key.
To enter a number...
·Press the key that is labeled with the desired number. The numbers
willfillinfromtheleftsideofthefieldsimilartoatypewriter. Youmust
enterany leading zerosinthe field. For example,ifyou wish toenter
“51” in a three space field, you must press the 0, 5, and 1 keys in that
order.
·Press the CLR key if you enter an incorrect number.

feedback tone can be turned off if you wish (see Section 4.5).
2.6 VIEWING MESSAGES
From time to time, the GPS 50 will use a message to tell you of conditions
thatneedyourattention. WhentheGPS50hasanewmessageforyou,the
MSG banner will flash. When this occurs, press the MSG key to view new
message(s). ContinuetopresstheMSGkeyuntilthepageyouwereviewing

Refer to Appendix A for a complete list of GPS 50 messages.
2.7 OPERATING MODES
ThreemodesareavailablewhichwillallowyoutooperateyourGPS50inthe
way which best suits your needs (see Section 4.2).
Normalmodeismostsuitableforhighdynamicsapplications. TheGPS50
will typically operate up to six hours on a single pack of batteries.
Battery Saver mode is suitable for most applications and will extend the
battery life to as much as ten hours.
Simulator mode allows you to simulate the operation of the GPS 50 while
athomeorinyouroffice. Thesimulatormodecanbeusedwhilelearningto
use your GPS 50 and is ideal for planning routes and entering waypoints.
KeepinmindthattheGPS50isnottrackingsatellitesinthesimulatormode.
You should never attempt to use the simulator mode for actual navigation.
If you are using your GPS 50 for the first time, we encourage you to review
Chapter 3 which introduces the GPS 50's basic features. Additionally, you
may wish to review Chapter 4 on custom setups. Afterward, you may want
to read through the rest of this manual and make further use of the built-in
simulator to practice with the advanced features.

CHAPTER 3
BASIC OPERATION
3.1 POWER ON
AfteryouturnyourGPS50on,itwillconductaseriesofselftestsanddisplay
the following notices: “VER x.xx”, “COPYRIGHT”, “1991-1992”, and
“GARMIN”. Following completion of the tests, the GPS 50 will begin
acquiringsatellitesthatwilltypicallytaketwominutestoobtainapositionfix.
Initially,theGPS 50 will displaythe“ACQ” banner;itwill inform youwhena
position fix is obtained by transitioning to either the “2D” or “3D” banner.
Whenfourormoresatelliteswithgood geometryareavailable,theGPS50
will automatically operate in the 3D mode in which latitude, longitude, and
altitude are computed. If only three satellites are available, the unit will
operatein2Dmodeinwhichonlylatitudeandlongitudearecomputed. When
operatinginthe2Dmode,theunitwillusethelastcomputedaltitudeoryour

YourGPS50willautomaticallyupdatesatelliteorbitaldataasitoperates. If
youhavenotoperatedyourunitforaperiodofsixmonthsorlonger,itwilltake
approximately 12.5 minutes to search the sky and collect new orbital data.
You will be informed when your unit is searching the sky with the message
“SRCH SKY”. Additionally, the “DATA” banner will be displayed. Once
satelliteorbitaldataiscollected,itwillbestoredinbatterybackedupmemory.
This means the data will not be lost when you turn your GPS 50 off.
