INTRODUCTION

Congratulations on your selection of the Trimble Navigation TRANSPAK GPS Personal Navigator! The

TRANSPAK

is a rugged, portable navigation device which receives and uses signals from the Global Positioning System (GPS) satellites to determine the time of day and your position, velocity, distance from locations, and time of arrival at a destination.

The

TRANSPAK

is a three-channel receiver that can track two satellites on two channels while sequencing on the third channel. This provides very stable velocity, heading and position solu-

tions under acceleration. In addition, LAND, SEA, or AIR modes can be selected to optimize the receiver dynamics for land, sea, or air navigation situations.

Your

TRANSPAK

was fully tested at the factory and will provide

years of trouble-free operation.

ABOUT THIS MANUAL

This manual provides information to quickly familiarize you with the

TRANSPAK

and enable you to use it to perform positioning

and navigation functions. The manual is arranged in three main parts: Description: describes the Global Positioning System (GPS)

and the

TRANSPAK

receiver, identifies the controls, indicators, and

connectors, and defines basic operations.

Operation:

describes how to prepare the

TRANSPAK

for use,

defines the functions it can perform, and provides essential information for each of the display formats.

Maintenance and Reference:

describes operator maintenance

and provides a list of the reference datums built into the unit.

The manual is organized for ease of use. In most cases, example screens or figures are presented on the left-hand page, and the corresponding text is located on the righthand page. In the Operation section, the descriptions of the operations are arranged in the same order as the rotary switch positions which select them.

For clarity, the same abbreviations displayed by the unit are used throughout the manual; refer to the Glossary for their meanings.

GPS and the TRANSPAK

GLOBAL POSITIONING SYSTEM (GPS)

GPS is a satellite-based radio navigation system. The system ul-

timately will be a constellation of 21 active satellites and 3 spares in orbits around the earth. This configuration will ensure worldwide operation with 24-hour, all-weather coverage. Each satellite transmits data that enables GPS receivers to provide precise position and time.

NOTE

Until the constellation is complete, coverage may be

limited

to specific hours of each day in certain areas of

the world.

TRANSPAK

The

TRANSPAK

GPS Personal Navigator is a hand-held, batterypowered navigation set that receives data from GPS satellites and calculates and displays position, velocity, time, and navigational data in any one of three operational modes: land, sea, and air. Three-dimensional fixes are obtained when tracking 4 or more satellites; 2-dimensional fixes can be obtained from 3 satellites plus user-entered altitude. The

TRANSPAK

receiver requires line-of-sight access to the satellite signals. Hold the unit level, with its intemal antenna facing toward the sky. GPS navigation signals are similar to light, so anything that blocks light will block or reduce the effectiveness

of the signals. The more unobstructed view of the

sky you have,

the better your

TRANSPAK

will perform. Avoid

placing your hands

an or over the antenna when the

TRANSPAK

is in operation.

Page 10

CONTROLS and INDICATORS

Page 11

Display Screen

The

TRANSPAK

displays information on the backfit 4-line LCD screen. The screen contents are determined by the rotary knob and user-selected options.

Rotary Knob

This 8-position switch selects the type of operation that the

TRANSPACK

will perform—for example: "POS" (positioning) op-

erations.

Ru (Left-Right) Switch

This 2-way switch is used to select items on the screen (indicated by a flashing box). Momentarily pressing the switch to the left or right selects different screen items.

pINC

DECq (Increment/Decrement) Switch

This 2-way switch is used to walk through numbers, letters of the alphabet, or options (as on a list). Momentarily pressing the switch upward or downward changes the value of the selected item on the screen.

The pINC-DECq switch is also used as a trigger when the

selected screen item represents an action to be performed

(indi

cated by brackets: <action>).

Both switches automatically repeat at a rapid rate when held on. This feature can be used to quickly roll up to high numbers or to scan past many screen items to select one farther on.

Low Battery

A battery symbol will blink in the

lower right corner of thescreen in all knob positions to indicate a low battery condi

tion. The

TRANSPAK

should be powered down and the

batteries

replaced or recharged when this symbol appears.

CONTROLS and INDICATORS

Page 12

Refer to Section 3,

Maintenance

(page 40), for procedures to remove or install battery packs, recharge the nickel-cadmium battery pack, and replace batteries in the alkaline battery pack.

External DC Adaptor

This adaptor enables the

TRANSPAK

to be powered by an external,

9- to 32-volt, 5-watt DC supply, such as a cigarette lighter outlet

in your vehicle. Refer to Section 3,

Maintenance

(page 40), for procedures to

remove or install the adaptor.

OTHER PARTS AND ACCESSORIES

This pack holds eight AA batteries and provides over 3-1/2 hours of continuous operation.

Optional:

Rechargable nickel-cadmium battery pack.

This pack also provides over 5 hours of continuous operation; it can be recharged in about 16 hours.

Page 13

OTHER PARTS and ACCESSORIES

Increased Storage Option

The standard

TRANSPAK

can store up to 99 waypoint descriptions in its internal memory. An optional configuration is available that will store up to 999 waypoint descriptions.

External Antenna Option

An optional external antenna with mounting hardware and cable

is available for stationary mounting of the receiver

antenna up to

50 feet (15 meters) from the TRANSPAK. The

external antenna can

be mounted to provide unobstructed

satellite coverage if the

TRANSPAK

must be operated indoors or

in a vehicle. When not in

use, the antenna connector dust cover

should be installed to keep

the connector clean.

HOW TO CHANGE DATA

Typical Screens

Waypoint units digit selected by initial pINC-DEC q

switch toggle.

Waypoint digit modified by subsequent pINC-DECq

switch toggles.

Waypoint number selected by t L-R u switch.

The

tL-Ru

switch only selects screen items; it does not

affect their values. However,

pINC-DECq

alters the

value of the selected item. Before using

pINC-DECq

make

sure the correct item is selected.

Page 19

HOW TO CHANGE DATA

Most screens contain some user-alterable items. These may

include numbers, letters, or options that can be changed, or "triggers" that cause an action. In this manual' s example screens, the alterable items are shown in reverse type.

On the screen, a flashing box indicates the selected item. The box

is represented by a gray shading in the example screens. Use the

tL-Ru

switch to select a different item. Pressing the switch once to the right selects the next screen item; left selects the previous item. At the last item, the next selection returns to the first item on the screen.

Using

pINC-DECq

alters the value of the item or triggers the action. Pressing the switch upward once changes the value of the selected item on the screen to the next level; downward changes to the next lower value. At the highest value, the next step returns to the lowest value.

For example, to change the waypoint identifier from 19 to 15 in

the TO line of the top screen (opposite page), use the

tL-Ru

switch to move the flashing box to the waypoint number (19 on second screen). Press the

pINC-DECq

switch once to open

the

item for modification; the digit 9 will flash. Then press the

pINC-DECq

switch down four times to change the value to 5

(third

screen).

Safety Timer

If no switches are pressed for 25 seconds, the selected item stops

flashing and

pINC-DECq

has no effect, thus preventing

acciden

tal changes. After this occurs, the

tL-Ru

switch must

be used

to once again select an item to be changed.

Turn-On

Page 21

Turn-On

Turn the

TRANSPAK

on by tuming the rotary knob to any one of the operating positions. A brief sign-on message is displayed, while the

TRANSPAK

performs a self-test. No switches are active during this time. When the power-on sequence is completed, the rotary knob position determines the type of operation.

Turn-Off

When you turn the rotary knob to OFF, the screen displays a 15second countdown before power is turned off. During the countdown, you can return the

TRANSPAK

to full operation instantly by

turning the rotary knob to another position.

Backlight Control

Pressing

pINC-DECq

during the turn-off countdown varies

the

screen backlight level. The backlight is off when the

TRANSPAK

is first turned on. Increasing the backlight level

increases battery

wear.

TURN ON/OFF

fixes.

GETTING STARTED: YOUR FIRST GPS FIX

Page 23

GETTING STARTED: YOUR FIRST GPS FIX

To turn the

TRANSPAK

on, rotate the knob from the OFF position

to the POS position. Your

TRANSPAK

was initialized at the factory with the date, time, and the location of Trimble Navigation. Initially, the POS screen will display the current date and time, and the LAT, LON, and ALT for Trimble Navigation. Once the

TRANSPAK

locks onto three SVs, the LAT, LON, and ALT fields

are updated to reflect your position. The operating mode is displayed in the lower right corner of the

screen. OLD indicates that the

TRANSPAK

is not performing

position fixes. This is to be expected when die

TRANSPAK

is first

powered on.

Your

TRANSPAK

can provide a fix in as little as 1 second, assuming that at least three SVs are "visible" to it. However, it may take as long as 5 minutes to get that first fix if the unit has been moved thousands of miles while powered off. You can expect to get your first position fix within 5 minutes with subsequent fixes at 1-second intervals. Refer to

Troubleshooting The

TRANSPAK

(page

44) if you are not getting fixes after 5 minutes of operation. The screens on the opposite page are typical for the POS

position.

Page 24

Altitude can be modified when AUTO is selected in the SETUP

position and the

TRANSPAK

drops into 2D operation.

A blinking

ALT field must be updated.

Altitude Entry Example

 ±

Example:

To set altitude to 4345 feet:

•

move to ± position and toggle to +

•

move to 10,000 position

•

if it already contains a value, set it to 0

•

if it is already at 0, ignore it

•

move to 1,000 position and set it to 4

•

move to 100 position and set it to 3

•

move to 10 position and set it to 4

•

move to 1 position and set it to 5

POS

Page 25

POS

Position information is displayed when the rotary knob is set to POS. If position fixes are not being performed (as when the

TRANSPAK

is first turned on), the word OLD will appear in the lower right corner of the display, indicating that the position is old.

Line 1 of the display shows the date and the time (a 24-hour clock is used) in either UTC, GMT (or Zulu), or local time. Local time is not labeled. Lines 2 and 3 show the position coordinates in degrees and minutes. Line 4 shows the altitude in either meters or feet and the mode of operation of the

TRANSPAK

(AUTO, 3D or

2D).

Entering Altitude

If the

TRANSPAK

is providing 2D fixes, you must manually enter an altitude. The altitude contains a 5-digit number preceded by a sign to indicate above (+) or below (-) sea level. Select the item by using the

tL-Ru

switch.

Change to the proper sign by pressing the

pINC

switch, then use

the

switch to move to the first non-zero digit and toggle in the desired value. If the remaining digits are zeroes, you are done; if other values are required, continue with the

and

pINC

switches until all non-zero values are displayed.

Only altitudes between -500m (-600ft) and +20000m (65000ft are allowed.

Altitude also can be entered in the

SETUP

Position.

Page 26

POS

Auto/2D/3D Operation

The

TRANSPAK

provides either 3D or 2D fixes. In AUTO mode,

TRANSPAK

uses signals from 4 SVs to provide position fixes in 3 dimensions including altitude. If only 3 SVs are available, 3D fixes are not possible; the

TRANSPAK

then performs 2D fixes (no

altitude). The

TRANSPAK

uses the last altitude either calculated by

a 3D fix or entered by the user.

The accuracy of the 2D fix

depends on the accuracy of the estimated altitude.

The

lower

right corner of the screen shows either AUTO-3D or

AUTO-2D

if the

TRANSPAK

is performing position fixes, or

AUTO-OLD if no

fixes are being made.

If the

TRANSPAK

is in AUTO mode and has been receiving signals from 4 SVs and loses contact with one of them, it switches from 3D to 2D operation. If you do not enter a new altitude value within 30 minutes, or if you move more than 1 mile from the position of the last 3D fix, the altitude field flashes, indicating that you should enter a new altitude. When 3D fixes resume, the

TRANSPAK

resumes display of the GPS-calculated altitude.

Your

TRANSPAK

typically is accurate to within 25 meters horizontally. Selective availability, a Department of Defense program to deny full GPS accuracy to unauthorized users, deliberately corrupts the GPS satellites' radio signals. When obtaining a 3dimension position fix, vertical (altitude) errors are 2 to 3 times worse than the horizontal errors (e.g., if your longitude is off by 25 meters, your altitude may be off by 50 meters).

Page 27

Manual 2D/3D Operation

Manual 2D

Manual 2D operation is intended for boating and other applica-

tions in which the altitude is not of concern. It provides for

entering a fixed altitude once and having the

TRANSPAK

perform

2D fixes without the need to update the altitude.

NOTE

It is vitally important that the altitude entered in manual 2D operation be correct to obtain accurate 2D fixes.

NOTE

Manual 2D/3D Operation is selected in the SETUP position.

The best way to ensure a correct altitude is to take a series of AUTO-3D fixes and use the GPS-calculated altitude when running in manual 2D.

Manual 3D

This mode is intended for the aviator and applications where

an estimate of altitude is just not good enough. Manual 3D operation provides for 3D fixes only. When 3D fixes are no longer possible,

TRANSPAK

will blink OLD until 3D fixes

resume.

POS

Page 28

(Screen shown in Land mode)

NAV

Page 29

NAV

The NAV knob position displays data to help you navigate from your present position to another position. In the NAV position, the

TRANSPAK

presents the Land, Sea, or Air screen format

selected in the SETUP position.

A typical Land screen is shown on the opposite page. The NAV

screen uses two waypoints to establish the great circle course between them. The NAV screen displays your velocity and heading, the range and bearing to the TO waypoint, and your distance (XTE) from the optimal course between the FRM waypoint and the TO waypoint. The TO field can be toggled between TO and FRM using the

pINC-DECq

switch to display the TO

and

FRM waypoints, respectively. Another TO or FRM

waypoint

can be selected from the waypoint library by

modifying either the

waypoint number or the waypoint label.

For example, to change the TO waypoint from 0 to 1, press the

tL-Ru

switch one time to the right. The waypoint number field

will blink. Press the

pINC-DECq

switch once to open the number field for modification; press it a second time to change the 0 to a 1. Whenever the TO waypoint is changed, the FRM waypoint is reset to your present position, thus defining an optimal course from where you are now to the TO waypoint.

Navigating with TRANSPAK

The figure on the opposite page shows how the present position is used to derive the range (RNG) and bearing (BRG) to the destination and how the velocity is used to find the heading (HDG). When a FRM waypoint is specified, the cross-track error (XTE) is calculated as the perpendicular distance from the unit's position to the straight line track between the source and destination.

This display provides the information required when you are traveling to your destination on foot or by car. Velocity, heading,

range, bearing, crosstrack error, and direction are

displayed.

Right crosstrack error indicates that the track

between the FRM

and TO waypoints is to your right.

SEA Mode

This display provides the information required when you are at sea. Speed over ground, course over ground, range and bearing, crosstrack error, and direction are displayed. The crosstrack error tells you which way to turn to reduce the crosstrack error.

Air Mode

Page 33

NAV

AIR MODE

This display provides the information required when flying to a waypoint. Bearing, distance, track, ground speed, estimated time enroute, and a course deviation indicator (CDI) are displayed. The CDI is calibrated to

unit (kilometer, statute mile, or nautical mile) of crosstrack error between vertical bars on the CDI. To reduce the crosstrack error, turn in the direction of the blinking vertical bar on the CDI.

In all three modes (Land/Sea/Air), if the

TRANSPAK

is not doing position fixes, the numbers displayed in VEL, RNG, BRG, etc. are replaced by asterisks. The units of measure for the display fields are selected by the METRIC/ENGLISH/NAUTICAL field of SETUP.

In the AIR mode, when the TO field is toggled to FRM, the BRG field changes to RAD and displays the radial from the displayed waypoint. The DIS field also displays the distance from the displayed waypoint. This is useful when you are flying away from a VOR.

TIME

The TIME knob position displays the date and time (24 hours, UTC or local), the estimated time of arrival (ETA), the time to go (TTG), and the time of the last fix (LAST FIX). Date of arrival is not indicated. In AIR mode, estimated time enroute (ETE) is

displayed rather than TTG.

The time of arrival and time to go are based on data entered in the NAV knob position. If the TO waypoint on the NAV screen is changed, ETA and TTG/ETE change accordingly.

The ETA and TTG/ETE fields are filled with asterisks if the

TRANSPAK

is not performing position fixes, or if you are moving

away from the TO waypoint.

It is not possible to modify the contents of a waypoint from the DIST knob position. The distance units (Km/MI/NM) and the bearing (T/M) are selected by the SETUP field (METRIC/ENGLISH/NAUTICAL) and (TR/ MG).

The radial to the FRM waypoint is supplied in the Air mode.

The WPT (Waypoint) knob position enables you to display, edit, and clear up to 99 waypoints (999 in optional configuration). Rotating the knob to WPT displays the waypoint selection screen. You can search for a waypoint, or enter one of the modes defined by the triggers (<FIX>, <EDT>, <R/B>, <CLR>) on the bottom of the display. You cannot modify or erase waypoints from the initial waypoint screen.

You may select a waypoint from the waypoint library by number, by label, or by alphabetic search.

Selecting a Waypoint by Number

To select a waypoint by number, press the

tL-Ru

switch until

the

waypoint numeric field is highlighted. Then press the

pINC-DECq

switch to open the numeric field for

modification and use

the

pINC-DECq

switch to modify the

number. Once the field has

been opened for modification, use

the

tL-Ru

switch to move

between the units, tens, and

hundreds digits.

Page 40

WPT

Selecting a Waypoint by Label

To select a waypoint by label, use the

tL-Ru

switch to high-

light the waypoint label field. Press the

pINC-DECq

switch

once to open the field for modification. Then use the

pINC-DECq

switch to select characters within the label field

and the

pINC-DECq

switch to alter the selected characters.

When the

pINC-DECq

switch is pressed, the highlighted character is modified to either the next or prior character and the waypoint library is searched for a match on the character string to the left of and including the modified character. If no match is found, the character is incremented or decremented again and another search is performed. If a next higher/lower label is found in the waypoint library, it is displayed. If the character string to the left of the selected character is unique, the label field will not change.

Selecting a Waypoint by Alphabetic Search

The alphabetic search field is located between the numeric field

and the label field. When the alphabetic search field is selected

using the

tL-Ru

switch, a character is displayed in

the space

between the numeric field and the waypoint label.

Pressing the

pINC-DECq

switch up displays the next

alphabetic waypoint

label; pressing it down displays the prior

alphabetic waypoint.

This provides a quick method of

scanning the waypoint library.

Page 41

WPT

Triggers

The <FIX> trigger stores the current fix into the next empty waypoint. The search for an empty waypoint begins with the displayed waypoint and is stored in that waypoint if it is empty. After the fix is stored, the waypoint into which the fix was deposited is displayed. The waypoint label field is filled either with the time if the fix was current or with the designator OLDFIX if the fix was old. You can edit the waypoint to rename the time. Time is stored as hours minutes seconds in six digits. The <EDT> trigger opens the currently selected waypoint for

modification. The waypoint number can be modified, which will copy the waypoint data into a new waypoint (copy a waypoint).

The waypoint label field can be modified by

moving into the

label field and using the

pINC-DECq

keys

to scroll through the

alphabet and numbers. The LAT and LON

fields can be modified

by selecting the field to alter and using

the

The <QUIT> trigger returns to the waypoint screen with no modifications made to the waypoints. Note that the distance units of the range are selected by the METRIC/ENGLISH/ NAUTICAL field of SETUP and that the bearing units are either magnetic (M) or true (T), based on die MG/TR field in SETUP.

The <CLR> trigger is used to clear a waypoint. You can clear the

selected waypoint by moving the blinking cursor to the <CLR> trigger with the

tL-Ru

switch and pressing the

pINC-

DECq

switch in either direction. The currently selected

waypoint is

displayed with the prompt

CLEAR

WAYPOINT <YES>

<NO>; <YES> is highlighted.

Pressing the

pINC-DECq

switch

clears the waypoint and the

next sequential waypoint is dis

played. A range of waypoints

is cleared by pressing the

pINC-DECq

switch a number of

times. To return to the Waypoint

screen, select the <NO>

field using the

tL-Ru

switch and press

the

pINC-DECq

switch.

In the Air mode, the BRG field can be toggled between BRG and RAD to enter either a bearing to or a radial from a waypoint.

STS

Page 45

STS

The STS knob position displays the status of

TRANSPAK.

Line 1

presents the number of satellites that the

TRANSPAK is

tracking.

Four SVs are required for 3D fixes. Three SVs are

required for

2D fixes.

Line 2 presents the current state of the GPS receiver: OK

indicates the

TRANSPAK

is making position fixes; N/A indicates that insufficient satellites are visible to make a fix; BAD indicates either that sufficient SVs are available but they are positioned such that a fix is not possible or that a receiver error has occurred; see page 44. The estimated accuracy of the fix is displayed if the

TRANSPAK

is making position fixes.

Line 3 indicates the window of satellite availability. 24-hour GPS coverage will be possible when the full complement of satellites has been launched. Until that time, there will be windows of GPS availability. If you are presently within a window of availability (sufficient SVs are visible), line 3 presents the amount of time remaining in the current GPS window and the start of the next window (REM 1:30 NEXT 14:14). If you are not now within such a window, line 3 shows the starting time of the next window and its duration (NEXT FIX 18:45 6:20). Time is displayed as local or UTC, as selected in the SETUP position.

Line 4 lists the operable antenna (INT or EXT for the internal or external antenna, respectively).

SETUP

The SETUP knob position displays the current display options. Each of the SETUP fields can be modified.

Time can be displayed in UTC, GMT, Zulu, or 24-hour local

time. When in the SETUP position, to adjust

TRANSPAK

time to

local time, use the

tL-Ru

switch to move the blinking cursor to

the UTC field. Use the

pINC-DECq

switch to set the local ti-

offset from UTC time. When you return to another

position of

the rotary knob, the correct local time will be

displayed.

The LAND/SEA/AIR field tailors the

TRANSPAK

for land, sea, or air operation. The AUTO/2D/3D selects the type of fix provided by the

TRANSPAK.

For a more detailed description of AUTO/2D/ 3D, see the POS section (pages 18 and 19). MGR/TR selects

either magnetic or true north for all heading

information.

NAUTICAL/METRIC/ENGLISH selects the

distance units. The last field selects the datum for LAT/LON display. All maps

have a reference earth model, or datum, relative to which the in

formation on the map is accurate. By selecting a datum,

you

select a LAT/LON correction which is applied to all LAT/

LON

displays. The correction is the difference between the

GPS

location of the datum and the survey's location of the

datum. The

LAT/LON displayed in POS and WPT will vary as

the datum is

varied. It is important to select the correct datum

for the map you

are using to have fixes that agree with the map

you are using. A

list of the datums included in the

TRANSPAK

is limited to recharging the NiCad battery pack or replacing the AA batteries in the non-rechargeable battery pack.

Recharging the NiCad Battery Pack

The NiCad battery pack provides more than five hours of continuous operation when it is fully charged. The battery pack charges to 85% of capacity in 16 hours and to full capacity in 24 hours. The battery pack slowly discharges when not in use and should be recharged prior to use if it has been stored for two weeks or more.

Removing and Replacing the Battery Pack or DC Adaptor

remove

the battery pack or DC adaptor:

Loosen latch at right-hand rear of

TRANSPAIC.

Pull latch end of battery pack or adaptor away from back of

TROUBLESHOOTING THE TRANSPAK

IF:

1. The

TRANSPAK

fails to power on.

•

Batteries are not connected.

•

Batteries are dead.

•

AA batteries are inserted incorrectly; check polarity.

2. The

TRANSPAK

fails to perform a fix.

•

The antenna may be blocked.

•

Ensure that there are no obstructions between the an

tenna and the horizon.

•

If you are using an external antenna, ensure that it is connected and that EXT is displayed on line 4 of the STS screen.

•

There may be too few SVs visible to obtain a position fix.

•

Turn the rotary knob to the STS

position. If NEXT FIX

and a time are displayed, there will be enough SVs

visible at the displayed time. If NEXT FIX: NO ALMANAC is displayed, the

TRANSPAK

must collect an

almanac from an SV, which takes 15 minutes.

•

The satellite almanac may be bad.

•

Turn the knob to the STS position. If NEXT FIX: NO ALMANAC is displayed on line 3, the

TRANSPAK

must

collect an almanac from an SV.

3. A receiver fault number is displayed.

If the

TRANSPAK

detects internal errors, it displays them on line 3 of the STS screen. These are "never should happen" conditions. Some of these errors are mere nuisances; others indicate

a serious problem which requires service — see

next page.

Page 53

essing error which may be transient. Turn the

TRANSPAK

off and then back on to clean the error. If

the error reoccurs, the

TRANSPAK

should be re-

turned for service.

Antenna feed line fault. This indicates an open or a short on the external antenna input. Check the external antenna cable for contamination (dirt, salt spray) or for an open or a short. A feed line fault should not occur when the internal antenna is in use. If it does, return the

TRANSPAK

for service.

Excessive bias dot. This indicates that the internal oscillator has drifted. The

TRANSPAK

will continue to operate, but should be returned for service if acquisition times become excessive.

SAFETY

The case of the

TRANSPAK

conducts electricity, even though it is made of plastic. When connecting the unit to an external power source, be careful to avoid electrical shock just as if the case were metal.

The

TRANSPAK

is designed for rugged use in difficult

field environments. It will operate continuously in air

temperatures from 0° to 60°C (32° to 140°F) and in

environments with up to 100% humidity. However, take reasonable care of the unit as with any other piece

of high-precision equipment.
