RDC sensorid Hex

[tsau]

Just installed new rdc sensor and tried to wake it up by deflating tyre, won't work. Then I went to local car tyre dealer. They had some Atoc device and it said the id is 340FB5. When I try to enter that id, F nor B are not accepted... what should I do?
Convert it to decimal?

Ps. Those of you wondering why don't I just try... I had no time today and if I need to go test ride, it's still winter here...
