If the other panel has no LOCK button, that panel’s TAKE button will blink.
To unprotect the output:
1. Press the PROT button again.
The PROT button will stop blinking.
If the output cannot be unprotected, it has been protected by another panel. The display will indicate “Protect” and show
the name of protecting panel.
An output may be force unprotected, no matter which panel protected it, if the password level of the unprotecting panel is
level 90 or greater. The password level is defined on the MPK Device table (page 5−107). This operation is useful for a master
panel capable of switching any source to any destination. The operator would be required to force unprotect the output prior
to changing its source selection.
For additional protect/lock information − see page 6−12.
CHOP OUTPUTS
To chop* an output, you must use the Category/number keypad. Select the first source and press TAKE. Then select the second
source and press CHOP. The CHOP button will blink, with the message “IN CHOP” displayed in the Current window.
The chop operation will automatically stop after approximately two minutes. The chop will finish with the source in the Preset
window being switched to the destination. The chop may be manually terminated by performing another source selection and
pressing TAKE.
For additional chop information − see page 6−13.
