Programming of the push-button response time
The INSERT and +48V push buttons on the front panel are tactile toggle switches. They can be programmed to 6 different
response times: 32 msec, 63 msec, 125 msec, 250 msec, 500 msec or 1 second.
The preferred response time depends on the temperament of the operator. Default factory setting is 250 msec, which is
suitable for most situations.
The unit is switched into programming mode by holding down the CH8 INSERT while powering up. The response time is
selected by pressing the CH1 to CH6 INSERT switches. The chosen setting is indicated by the corresponding INSERT
LED and is immediately saved into memory. No need to do anything special.
To exit the programming mode, press CH7 INSERT or turn the power off or wait 15 seconds for automatic exit.
The graphical representation on the next page illustrates the procedure.
