6. Setting of the presets
If a push-button with an arrow or the "P" push-button is
pressed, the device jumps from the display of the counter
to the display of the preset. About 4 seconds after the last
operation of the button, the device jumps back to the dis-
play of the counter and takes over a new preset value.
Exception: in the time counter mode, the new value is
taken over immediately.
Once the preset is displayed, the " " push-button allows to
choose the decade to be modified. This decade then blinks
at a 1 Hz frequency. The "" push-button allows you to
raise the value of the decade. On the most significant
decade, after the value "9", the sign "-" is displayed. The
following operation of the "" push-button displays "-1"
again. A new operation of the "" push-button lets the dis-
play of this decade start again at "0".
Caution: in case of automatic repetition, the preset cannot
be given negative values.
