29 QM4H Changing the time setting • It is possible to use the up and down keys to change the time setting even during timer delay. However, attention should be paid to the following. 1) When the time setting is shorter than the elapsed time, and timer delay is set in the plus direction, the time setting will return to “0” after the timer delay reaches full-scale, timer delay will be performed up to the changed time setting, and time up will be reached. 2) When timer delay is set in the minus direction, timer delay will be performed up to “0” regardless of the time, even if the time setting...
