REMARKS ON BATTERY REPLACEMENT
• Remarks on installing the battery
· Keep the battery level while installing it lest it should
touch the circuit block cover.
· Be careful not to short-circuit the battery connection (–)
and the circuit block cover. If this occurs, the display may
remain blank after the battery is installed.
* If the display remains blank, wait until the battery voltage
returns to the normal level. The normal display will
return.

• Remarks after installing the battery
III.
▼
After the battery is replaced with a new one, or after
the battery is re-installed following the repairing
procedures, be sure to short-circuit the AC terminal
of the circuit block and the circuit block cover with
conductive tweezers for more than 2 seconds as
illustrated at right to reset the circuit.
REMARKS ON DISASSEMBLING AND REASSEMBLING
Use the universal movement holder for disassembling and reassembling.

Case
Module (Only for Cal. S143A)
The jack and the jack lead terminal are soldered together.
• How to remove
Unsolder them with a soldering iron, soak up the
melted solder completely with a solder wick or the
like, and then, remove the jack lead terminal.
Soldered portion
Liquid crystal panel
• How to install
Set the jack lead terminal to the jack pin, taking care
not to set it upside down. Then, re-solder them with
the soldering iron.
Jack lead terminal
Note: When using the soldering iron, take utmost care not to deform or damage the case and other
parts by the heat of the soldering iron.
5
Jack
The jack is only available for supply with the nut.
• How to install
To reassemble the jack, set the notch of the jack to the groove of the case.
9
Buzzer lead terminal
• How to remove
Remove the buzzer lead terminal after detaching the circuit block case from
the circuit block.
• How to install
To install the buzzer lead terminal, set the end portion of the buzzer lead
terminal to the groove of the circuit block case, and then, turn the buzzer lead
terminal slightly so that it does not come off.

Set the switch connector with the conductive
portion (black) up.
IV. VALUE CHECKING
• Current consumption
:
Less than 12 µA (with voltage of 3.0 V supplied from a battery)
For the circuit block alone :
Less than 10 µA (with voltage of 3.0 V supplied from a battery)
For the whole module
How to measure the current consumption
While applying the probe of the tester as shown in the illustrations below, reset the circuit with conductive
tweezers for more than 2 seconds. Then, measure the current consumption.
For the whole module
For the circuit block alone

Switch operation of the System Printer SP12
Print mode selection switch : Split time and lap time are printed out while the switch is set at “LAP.
SPLIT”.
Power switch
: The switch turns on and off the printer. (When the switch is set to “ON”,
the roll paper will be advanced by one line.)
• Checking the operation of the Stopwatch Cal. S143A and the System Printer SP12
Printout during the measurement
1.
Turn on the power switch of the printer.
2.
Slide the print mode selection switch of the printer to “LAP. SPLIT”.
3.
Press button “D” to show the STOPWATCH mode.
4.
Press button “A” to start the measurement. The block number, for example, “BLOCK : 1” will be
printed out.
* If the stopwatch is counting, press button “A” to stop the measurement, press button “B” to reset
the digits to “00”, and then press button “A” again to start the measurement.
5.
Press button “B” repeatedly. With each press of the button, the split/lap number, split time and lap
time will be printed out.
Printout of the stored data
* Measure the split and lap times without connecting the stopwatch and the printer.
1.
Press button “A” to start the measurement.
2.
Press button “B” repeatedly to measure split and lap times.
3.
Press button “A” to stop the measurement.
4.
Connect the stopwatch with the printer, turn on the power switch of the printer, and then, slide the print
mode selection switch of the printer to “LAP. SPLIT”.
5.
Press and hold button “C” for 2 to 3 seconds. “PRINT ALL” will be displayed.
6.
Release button “C”. All the stored data will automatically be displayed and then printed out
successively.
Printout of the elapsed time
1.
In the STOPWATCH mode, press button “B” to reset the digits to “00”.
2.
Press button “D” to show the TIME/CALENDAR mode.
3.
Press button “A” to start the measurement. The year, month, date and starting time will be printed out.
4.
With each press of button “B”, the time and number of measurements are printed out.
* The elapsed time cannot be printed out by pressing button “C”.
* If the digits have not been reset to “00”, the time cannot be printed out.
If the measurement data are not printed out properly, check the following points for the cause of failure.
1.
Check if the connecting cord (SC-11) is broken, by using the tester.
2.
If the batteries of the printer have run down, replace them with new ones.
3.
Check if the soldered portion of the jack lead terminal of the stopwatch is damaged to cause short
circuit.
* If the printer will not operate properly after correcting the above conditions, take both the printer and
the stopwatch to a SEIKO SERVICE CENTER for repair.
* Please be informed that the repairs of the System Printer SP12 will be made only at the SEIKO
factory.
