INTRODUCTION
The Lathem LT Series time stamps are considered "standard" by thousands of
businesses and institutions because of their low initial cost and years of proven,
trouble-free operation. The LT Series offers a wide variety of registration com-
binations that may be used for timing, numbering, and dating functions. The LT
Series consists of five models, and is designed to meet virtually all of your
validating needs. Standard features include: dual registration, allowing auto-
matic or manual action; motor-driven ribbon shift for smooth, quiet operation;
easy ribbon changing; registration position adjustment; and registration impact
pressure control. Available options include a digital display, as we!! as repeat
and advance numbering. All units carry a full one-year factory warranty.

24-HOUR FORMAT

also known as the Continental (0-23 hour) format. The time type wheel sections
can print in 24-hour format for an additional charge.

GETTING STARTED
Getting started with the LT Series iseasy. There are only a coupleoffundamental
decisions that must be made. After that, it's a breeze.
1. Plug the unit into the wall outlet.
2. Set the type section.
3. Set the digital clock (optional feature).
4. THAT'S IT! You're ready to go.

INSTALLATION
The LT Seriestime stamp installseasilyonany tabletop orflatsurface. Determine
whetheryouhavea 110/120VACor220VACunit,thenplugitintoanyappropriate
AC wall outlet. (Note: Avoid outlets with On/Off switches. These outlets may
be accidentally turned off, causing an interruption of the timing action.)
DUAL REGISTRATION
When forms are fully inserted into the
stamp, an automatic trigger causes reg-
istration. There may be times when it is
desirable to create a manual registration.
The LT Series gives you that option. To
operate manuaIly, insert a form to the
desired position by aligning the desired
registration position with the print lo-
cators (Figure J, Number J) on the side
of the case. When the form is properly
aligned. press the manual registration
switch on the front of the unit (Figure j,
Number 2).

SETTINGTHETYPEWHEELS
As noted in the earlier sections LT SERIES MODELS and OPTIONAL FEA-
TU RES, the LT Series Models are available with a variety of date, time, and num-
ber wheels. You may set the applicable type wheels according to the following
directions.
] . Disconnect the power source.
2. Remove the top cover by inserting the key in the back of the unit, turning the
key clockwise, and pulling the cover up and forward.
.,
-'. Remove the frame locking pin (Figure 2, Number I). Lift the top frame
(Figure 2, Number 2) to access time and date type wheels (Figure 2, Num-
ber 3) and number type wheels, if applicable.
4. Depress the time type setting lever (Figure 2, Number 4). Using a small
screwdriver or similar tool, rotate each individual date and time type wheel
down to the correct date and time. (Note: Month and date type wheels
must be reset manually the first day of each month.)
5. Depress the number type setting le-
ver (Figure 2, Number 5) and rotate
the number type wheels (Figure 2,
Number 6) to the correct position. 2
6. Close the top frame and insert the
locking pin, positioning the pull ring
down and inside the case. Reinstall
the top cover, fitting the top se-
curely into the grooves in the main
frame case. Lock the top in place. Figure 2
7. Connect the power source.
8. Make a registration to check for
accurate date, time, and number
readings. If necessary, reset the
digital display. (See Page 7.)

LT Series OperationsManual Page 7
SETTING THE DIGITAL DISPLAY
Models with a "C" affixed to their designation (LTTCand LTTNC)denote units
featuring a digital display. This display may be used in the 12-hour AMJPM
format or the 24-hour (Continental) format. The digital display should always
be synchronized with the time type wheels. To set the digital display and syn-
chronize the display with the time type wheels, do the following:
..-..
1. Connect the power source.
2. Locate the three (3) push-buttons
labeled SEC, HRS,and MlN on
the bottom ofthe unit. (figure4,
Number 1)
3. Return the unit to its upright position with the digital display facing towards
you. Pull the unit forward slightly so the front hangs over the edge of the
table, thereby giving you access to the buttons. (Remember: The'minute
button is on the right.)
4. Make a registration to see what time is indicated by the time stamp. Usethe
HRS (center) and MIN (right) buttons to set the time to the hour and
minutes indicated on the registration.
5. Place yourfinger on the minute button (right) but do not press itjust yet.
Listen for the type sectionto advance, you will hear an audible click. When
you hear the click, immediatelypress the minutebutton to advance one
minute. Secondsare now synchronizedwith the type section.
6. Make another registration to check the imprint feature for accuracy.
(Note: Interruptions in power lasting more than 3 to 5 seconds will cause the
digital display to flash, indicating that it is necessary to reset the display.)
ADJUSTING PRINT IMP ACT
Print impact may be set to any desired level, from very hard to very light.
The impact adjuster is located on the bottom of the unit. Turn the adjuster
to the right to increase or left to decrease the impact.
(NOTE: To extend the effective life-spanof the unit, use the lightest
adjustment possible, which still gives a legible imprint.)

Page 8 LathemTimeCorporation
CONSECUTIVEIDUPLICATECOUNT (Numbering Units)
Units equipped with the numbering feature may be configured for
Consecutive Count, advancing the number type wheel after each
registration, or Duplicate Count, advancing the number type wheel after
every two registrations. All units are shipped with the Consecutive Count
mode enabled.
To switch to the Dupicate Count mode, disconnect the power. Locate and
remove the Access Cover (Figure 5) using a philips-head screwdriver. The
shunt is placed over 2 pins (Figure 6), remove the shunt and place it over
just 1pin. To return to the Consecutive mode, reverse the procedure.

ADJUSTING THE REGISTRATION POSITION
Depending on thetype of document being stamped, it maybe necessary to change
the registration position. This can be accomplished by moving the trigger as-
sembly. The trigger assembly has a range of motion of about two (2) inches
forward or backward. The trigger assembly tells the unit how far the document
must be inserted before activating the stamp. The print locators on either side
of the top cover (Page 5, Figure 1,Number 1)can help you center the registra-
tion point.
To adjust the registration position:
I. Disconnect the power s(lurce.
2. Remove the top cover/and frame locking pin as described on Page 6. Lift
the top frame.
3. Loosen the trigger adjustment screw (Figure 8, Number 1) and s1idethe
trigger assembly (Figure 8, Number 2) to the desired position. (Note:
Moving the trigger assembly towards you p1acesthe registrqtion closer to
the edge of the document. Moving the trigger assembly away from you
places the registration farther from the edge of the document.)
4. With the trigger assembly in the desired position, tighten the trigger adjust-
ment screw.
5. Close the top frame, install the frame locking pin, and rep1ace the top cover.
6. Connect the power source.
7. Make a sample registration. If the registration is not in the desired loca-
tion, readjust the trigger assembly by following the previous six steps. If
the registration is in the desired location, reset the type wheels (see Setting
the Type Wheels, Page 6) and the digital display (Setting the Digital Dis-
play, Page 7).

CHANGING THE FUSE
Each model of the LT Series comes equipped with a fuse. The fuse protects the
unit from damage in case of a power surge or electrical overload. If too much
power reaches the fuse, the fuse burns out, or is "blown," stopping operation of
the unit and avoiding costly damage.
To change the fuse:
I. Disconnect the power source.
2. Remove the top cover and frame locking pin as described on Page 6. Lift
the top frame.
3. Locate the Fuse Holder Cap (Figure 10,Number 1).
4. RemC?vethe fuse cap by turning counterclockwise. Remove the old fuse.
5. Insert a 3 Amp replacement fuse (Type 3AG or equivalent). Press down on
fuseholdercapandturnclockwiseuntilit locksin place. .."
6. Close the top frame, install the frame locking pin, and install the top cover.
