MDO34 Internal noise on power up. New Unit

Hello,

I have a brand new MDO34. When I power on the MDO34 after being off overnight, the unit makes a random low volume muted clicking sound.
The range and cycle changes during the power on. Almost sounds like a very slow speed fan blade tick.

Sound ceases after about 5 mins of power on time. Maybe the function generator is performing a self test?

Is this normal?

Hello,

These sounds are standard for the power up time of our instruments. In these five minutes, the scope is running tests and diagnostics to ensure everything is working properly inside the unit.
