Open the lid and check that it actually has a 10811A rather than a simple gate oscillator.
We have so far refrained from opening it to preserve the right of return. Did HP ship 5370Bs with lesser oscillators than the 10811? I had assumed that if there is not a 10811 it's because someone subsequently swapped it out.
