MSO channels toggle

[Eknolspk]

Hi.
I just received my 2205 MSO scope, but I have some problems that some NOT connected MSO channels are toggling high.
For example, I've connected a 3.3 V, 10 kHz clock pulse on D0 and ground. I measure the same clock pulse with analog CHA. This is as expected.
But I also see some very short "HIGH detections" on D1 and D5 at rising edge of D0. This pins are NOT connected. Only D0 and ground are connected in MSO connector.
When I connect analog CHB to D1 it show 0.7 V, and is increased about 50 mV synced with clock pulse measured on D0/CHA. Level settings on all DI is set to 1 V.
Am I missing something here, or is my scope broken?

Thankful for reply.
Anders
