INTRODUCTION
The Lathem 4000 Series time rectrders are considered "standaid" by thousands of
businesses and institutions because of their low initial cost and years of proven^
trouble-free operation. Many options are available with models to fit most business
needs for payroll and job timekeeping. The DWA-4000 series features touch plate
or automatic registration, right or left margin imprint, self reversing ribbon, digital
time display, coined steel type wheels, and easy installation. A p^uticularly useful
feature of the DWA-4000 series is akeypad-programmable signal relay, c^>able of
ringing bells (c^ other signal devices) at selected times as well as inhibiting their
(^ration when not desired.
Read all directions carefully before operating (h* maintaining the DWA-4000.
Should it be necessary to return the unit, retain the original packing materials for
shipping. Thisop»aiionsmanualisdesignedloprovidebasic(^)eratinginstiiictions.
Minor maintenance and adjustments can also be performed easily and effectively
by referring to these instructions. For service beyond the scope of this manual,
contact the dealer fiom whom the equipment was purdiasod or Lathm Time Company.

Before proceeding, you need to know the “registration time format” of your time
recorder. The fourth digit in the model number indicates this format. EXAMPLE;
Since the fourth digit in the model number 4054 is a “4”, it will print with 0-59
minutes and 0-23 hours, along with month mid'date (See Page 2).
1. Plug the clock into the wall sodcet
2. Install 9 V alkaline battery (not supplied).
3. Choose the time format desired. (Below)
4. Set the type section. (Below)
5. Set the digital face. (Page 9)
6. Program the signals. (Page 10)
7. THATS IT! You’re ready to go.
TO CHOOSE THE TIME FORMAT
The clock defaults to the 12 hour fmmat and will af^iear on the di^lay as

The clock's display and type section keep time according to line frequency (typically
60 Hz). During power failure, the unit automatically switches to an internal quartz
crystal to maintain time. A 9<voltnon-rechargeable battery maintains display time
and memory for up to 15 accumulated days. When power is interrupted, the digital
display disappears with the exception of the flawing colon.
When power is restored, the display indicates the correct time and day, and all
programmed signals are intact If the PM indicator is flashing when power is restored
the type wheels may need to be reset and synchronized with the time display. To
verify whether or not the type wheels should be re-synchronized with the display:
1. Press To clear the flashing PM indicator and set the clock in
normal mode.
2. Use a piece of p^pcr and make a registration on it by inserting it into the
card receiver.
3. Compare die registration with what is shown on the display. If they
match, there is no need for further action. If diey don't match:
4. Go to "GETTING STARTED” on page 7 and follow the steps for
"SEniNGTHETYPESECnObrarKi"SErnNGTHEDIGITALFACE”.
Since the battery is non-rechargeable, it should be replaced when the display
indicates ”Lo”.

HOW TO CHANGE A RIBBON
Lathem time recorders have self-
reversing ribbons. With normal use, a
ribbon should last for many months or
even years...and when the time comes,
it is easy to change.
1. Remove the top cover and raise
type section (see “Raise the type
section on page 7.)
2. Ranove the cotter pins (Fig. 8,7)
that retain the ribbon spools and
slide off old spools.
3. Liftribbonshield(Fig.8,15)—use
pencil to support in up position.
4. Remove ribbon and replace with
HGURE8
new Lathem ribbon. Make sure the
ribbon feeds frtnn bottom of spools
and runs BETWEEN reversing
fmgers (Fig. 8,10), the red side aligned with date wheel(s).
5. I nstaU cotter pins, remove pencil, and lower type section into place.
HOW TO CHANGE A TYPE SECTION
If your type section needs servicing,
you can easily remove and replace it
with a spare, without sending the entire
machine for service. Here’s how:
1. Remove the top cover.
2. Remove type section retaining ring
(Fig. 1,12).
3. Unplug connectors (Fig. 9,18).
4. Lift type secticm slightly and move
it to the right to release hinge pins
(Fig. 9,24) from their sodcet (Fig.
9,25). Unit wiU lift out (Fig. 9).

Operation Manual Addendum
DWA-4000
To improve the performance and reliability of this product, we have
replaced the previous 10 AMP Dry Contact Relay, with a 10 AMP
Solid State Relay. The new Solid State.Rclay only operates with 24 -
240 VAC external devices (bells, horns, etc.). External DC powered
devices should not be connected to this unit.
Due to this change, please note the following corrections to this
manual:
Inside Cover Signal Relay is no longer a Form A (10 AMP) Dry
Contact, instead it should read 10 AMP Solid State
24 ^ 240 VAC Only.
