1) Setting or changing the operational mode
(1) When the UP or DOWN key at the first digit is pressed with the set/lock switch
pressed, the mode is changed over to the setting mode.
(2) Now release the SET/LOCK key.
(3) The operational mode in the setting mode is changed over sequentially in the left or right direction by pressing the up or down key at the first digit, respectively.
(4) The operational mode displayed at present is set by pressing the RESET key, and the display returns to the normal condition.
2) Checking the operational mode
When the UP or DOWN key at the second digit is pressed with the set/lock switch pressed, the operational mode can be checked.
The display returns to the normal condition after indicating the operational mode for about two seconds. (While the display indicates the operational mode for about two
seconds, the other indicators continue to operate normally.)
3) Setting the lock
When the UP or DOWN key at the fourth digit is pressed with the set/lock switch pressed, all keys on the unit are locked.
The timer does not accept any of UP, DOWN and RESET keys.
To release the lock setting, press the UP or DOWN key at the fourth digit again with the set/lock switch pressed.
* Operational mode, adding and subtracting and minimum input signal range cannot be set at T
4) Changing over the T
The T1/T2 setting display is changed over by pressing the SET/LOCK switch. (This operation gives no effect on the other operations. The set time and elapsed time

• Changing the set time
1. It is possible to change the set time with the up and down keys even during time delay with the timer. However, be aware of the following points.
2. When the set times at T
becomes OFF.
1) If the set time is changed to less than the elapsed time with the time delay set to the addition direction, time delay will continue until the elapsed time reaches full
2) If the time delay is set to the subtraction direction, time delay will continue until “0” regardless of the new set time.

time reaches the new set time.
