How do I stop my Grundig SC 303 radio switching off with the ignition?

on/off logic [ignition operated]when the vehicle ignition is switched off,the radio if on,will also be switched off.when the ignition is switched on again the radio will also be switched on again. the on/off logic via the ignition can be disabled so that the unit can only be switched on/off by the button.[logic off] to switch off the logic,switch on the ignition,press and hold the the station presets1 and 3 and switch the set on.keep the presets pressed until a bleep is heard.[logic on]to switch the logic back on repeat the procedure for logic off.[note]if the unit is disconnected from the power supply, when reconnected it will have the logic on. regards jim
