PRT82MF).
Remove connections to CLK and DTA terminals
Connect CLK with DTA
Restart the controller (place and remove jumper on RST contacts – see fig. 5 or switch power
supply off/on) - continuous acoustic signal shall be generated
Disconnect CLK and DTA
Connect PRT series reader with keypad (e.g. PRT82MF) to CLK and DTA lines (without switching
power supply off) and execute further steps by means of that reader.
