INTRODUCTION
The Lathem 4000 Series time recorders are considered "standard” 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 particularly useful
feature of the DWA-4000 series is a keypad-programmable signal relay, capable of
ringing bells (or other signal devices) at selected times as well as inhibiting their
operation when not desired.
Read all directions carefully before operating or maintaining the DWA-4000.
Should it be necessary to return the unit, retain the original packing materials for
shipping. This operations manual is designed to provide basic operating instructions.
Minor maintenance and adjustments can also be performed easily and effectively
by referring to these instructions. For service beyond the scope of this manual,
con tact the dealer fixxn whom the equipment was purdiased or Lathem Time Company.

INSTALLATION INSTRUCTIONS
The DWA-4000 Series can be set on a desk or shelf, or mounted on a wall. Wall
p anting is recommended for payroll use because the clock can be installed at eye
level (about fourfeetfrom the floor to the card receiver). This provides the employee
with good aim for aligning his time card to the red pointer. Once the clock has been
installed, mount the bell(s) and or born(s) at the desired location(s). With the power
cord unplugged, wire the signal devices, through a single gang outlet box, to die
connector plate (two wiring schemes are shown in the diagrams below); mount the
connector plate to the outlet box, and insert the plug of the bell cord (Fig 1,22).

The type wheels and the digital clock function
independently of one another. Setting the
digital clock does not set the type wheels.
Similarly, setting the type wheels does not
set the digital clock. Each assembly must be
set individually and synchronized.
No security code is required to access program
functions since the keypad is behind the
locked cover. Unlock and remove the case

GSTARTED
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 socket.
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. THAT'S IT! You're ready to go.
TO CHOOSE THE TIME FORMAT
The clock defaults to the 12 hour format and will appear on the display as
12:00, if the 12 hour format is desired, no action is required. If 24 hour
format is desired:
1 .

NOTE: If your machine records in 1-12 hours, the PM hours are underlined. AM
hours are not underlined. Set time to the proper hour of die day to avoid errors
such as setting the day wheel to the next day at noon rather than midnight
5. Use a pointed object to rotate each
wheel until the correct time and day
are vertically aligned at the center
position, as shown (Fig. 6,23). If
you are using tenths (models with
4th digit of2 or 5), go to the section
“Setting Decimal Wheel with
Tenths” If you are using hundredths
or 0-23 hours, refer to the Dial of
Decimal Equivalents in Figure 7 to
determine the correct setting.
6. Rotate the main drive wheel to
advance the wheels for any time lost
during this setting procedure.
7. Release the white open latch by
pressing left. Gently lower the type
section.
8. Press firmly against face of the type section to lock into the closed position.
FIGURE 6
DIAL OF DECIMAL EQUIVALENTS
The dial in Figure 7 shows the tenths
andhundredtbs setting for each minute.
The small inner circle represents
minutes, the middle circle represents
tenths, and the outer circle represents
hundredths. For example:
45 minutes=.7 tenths = .75 hundredths.
Setting Decimal Wheel with Tenths
NOTE: Use only for recorders
printing in tenths (models witha4th
digit of “2” or “5”)
1. Rotate Tenths Wheel and set it at
“9”. A wheel is set when the desired
number is in line with 6:00 on the
clock face. FIGURE 7
2. Rotate Main Drive Wheel (Fig. 2,
16) until the Tenths Wheel clicks over from “9” to “0”.
3. Rotate Hour Wheel to set current hour.
4. Set correct minutes by rotating Main Drive Wheel one time each minute.
For example, at 10:05, rotate 5 times = 5 clicks * 5 minutes past ten o’clock.
