CONTROLS/INDICATORS
ON/OFF button turns unit on and off.
FORMAT/(ALM) button permits timing in four different formats:

decimal seconds, decimal minutes, decimal hours and clock.
Illuminated LED indicates the current timing format. During alarm
operation, FORMAT/(ALM) button allows user to advance digits.

DISPLAY/(ALARM) button allows user to view the running time of the

internal clock while unit is in Cumulative or Interval Timing mode.
During alarm operation, DISPLAY/(ALARM) button permits setting,
changing and deleting an alarm.

MODE/(ALM) button permits timing in four different modes: start/

stop, cumulative, interval, and time-out. Illuminated LED indicates
the current timing mode. During alarm operation, MODE/(ALM)
button allows user to select each digit on display for individual digit
advancement.

RESET button resets the internal clock and display to zero.
START/STOP button permits starting and stopping timing opera-

tions, performs time-outs and resets display to zero, depending on
current mode and number of times pressed.

TIMING OPERATION
Single action timing

In Single Action Timing mode, unit times uninterrupted single events.

the internal clock automatically resets to zero and begins timing.

6. Successive presses of START/STOP button “freezes” the display
and shows the elapsed time since the previous press.

7. Press DISPLAY/(ALARM) button to “unfreeze” display and show
the interval running time.

Time-Outs

In Time-out mode, unit permits any number of stops to be performed.
Unit stops and restarts internal clock upon user command. Total
cumulative time will not include time-outs.

1. Press MODE/(ALM) button until START/STOP light illuminates.

2. Press FORMAT/(ALM) button until desired format light
illuminates.

3. If display is not at zero, press RESET button to return display
to zero.

4. Press START/STOP button to begin timing.

5. Press START/STOP button a second time to stop clock for a
readout.

6. Press START/STOP button a third time to automatically reset the
internal clock and return the display to zero. This action also
restarts clock.

Cumulative Timing

In Cumulative Timing mode, unit records any number of cumulative
timing breaks while internal clock continues.

NOTE: Blinking digits on display indicate the internal clock continues.

1. Press MODE/(ALM) button until TIME OUT light illuminates.

2. Press FORMAT/(ALM) button until desired format light illuminates.

3. If display is not at zero, press RESET button to return display to
zero.

4. Press START/STOP button to begin timing.

5. Press START/STOP button again to stop timing for a time-out
(both internal clock and display will be halted).

6. Press START/STOP button a third time to resume timing from the
point at which it was stopped.

Simultaneous Timing

Up to 12 events may be timed using any combination of the available
timing modes (start/stop, cumulative, interval, time-out) and timing
formats (decimal seconds, decimal minutes, decimal hours, clock). To
view the status of any timed event, simply use MODE/(ALM) and
FORMAT/(ALM) buttons to enter appropriate timing mode and
format.

WARNING: When an attempt is made to set more than 12 different
event times or more than 4 alarms, unit emits a signal and the display
will not respond to the keyboard.

Continuous Timing

For events lasting longer than the unit’s maximum timing capacity, unit
instantly rolls over to zero and continues timing.

ALARM OPERATION

Up to four alarms may be set. When an alarm time is reached, an
audible alarm sounds while timing continues.

WARNING: Turning off unit clears all preset alarms.

Setting an Alarm

1. Press MODE/(ALM) button until desired mode light illuminates.

2. Press FORMAT/(ALM) button until desired format light illumi-
nates.

3. If display is not at zero, press RESET button to return display to
zero. Alarms may not be set unless display is at zero or timing
is stopped.

4. Press DISPLAY/(ALARM) button. The far lefthand digit will blink,
indicating the alarm is ready to be set.

5. Press MODE/(ALM) button to select each digit on display until
desired digit begins blinking.

6. With desired digit blinking, press FORMAT/(ALM) button to
advance digit to desired setting.

7. Repeat steps 5 and 6 until desired alarm setting is displayed.

8. Press DISPLAY/(ALARM) button to return to normal timing
operation. The alarm is now set.

(ALM) buttons until the appropriate lights are illuminated.

2. Press DISPLAY/(ALARM) button. The far lefthand digit will blink,
indicating the alarm is ready to be set. The current alarm setting
will be displayed.

3. Press DISPLAY/(ALARM) button to return to normal timing
operation.

Deleting an Alarm

Adjusting Alarm Volume

The unit features a Volume Adjustment Screw that controls the
volume of sounding alarms and the audible “click” produced when
any button is pressed.

1. Turn unit over to expose its four rubber feet.

2. Using a small screwdriver, turn Volume Adjustment Screw,
located in hole on bottom of case, clockwise to increase alarm
and “click” volume. A counterclockwise turn decreases alarm
and “click” volume.

WARNING: Do NOT insert anything into the sound transducer hole
located at the rear of the unit. The alarm speakers within may be
damaged.

Default Alarm Sounds

When a preset alarm setting is reached, unit will sound an alarm and
the corresponding mode/format lights will illuminate to indicate which
alarm is sounding. If more than one alarm sounds, the first alarm
heard will sound one beep per second. The next alarm will sound two
beeps per second, etc.

AC CONNECTION

Connect the power supply to a 120-volt, 60 Hz AC electrical outlet
and insert the DC power plug into the jack located at the rear of the
digital timer. Use only the power supply supplied with the unit.
When plugged into an outlet the power supply is normally warm to
the touch.

CLEANING

Clean the membrane switch with a clean, lint-free cloth. A damp cloth
may be used to clean a spot. Do NOT use cleaning fluids or solvents.

BATTERY BACKUP

The unit has a 9-volt alkaline backup battery for uninterrupted
operation during brownouts or power failures. Replace battery
annually. A fresh battery will maintain timing continuously for over
one week.

NOTE: During power outages, all timing operation will be maintained
by the backup battery. However, the digital and LED displays will
NOT function and the buttons will NOT respond when pressed.

1. Verify unit is unplugged, turn unit over and remove the four
rubber feet.

2. Using a screwdriver, remove the screw from each of the rubber
foot positions.

3. Remove lower portion of case to expose battery compartment.

4. Attach the supplied 9 volt alkaline battery to the battery clip. Replace­ment battery Cat. No. 1112.

5. Reposition lower portion of case and reattach the case by
inserting and tightening the four screws removed in step 2.
Replace rubber feet.
