CAUTION:
- Do not bend the CryoProbe.
Do not hold the CryoProbe at its upper tube, always carry it at its body.
- Do not open the CryoProbe.
There are no user-serviceable parts inside. A CryoProbe cannot be sealed
or reassembled without special equipment. Even undoing some screws can
destroy factory settings and will in general render the CryoProbe unusable.
- Never force a CryoCoupler into position.
- Do not obstruct the operation of the safety-valves on the top and front faces of
the CryoProbe body.
- Do not move a cryogenically cold device.
- Do not try to fix a leak on a cold part because cracking of frozen o-rings, valves
etc. may occur.
- Excessive RF power can destroy the CryoProbe or the HPPR CRP. Obey the
limitations given on the specific ‘L
IMITATIONS - WARNINGS’ sheet. See also
"RF power limitations" on page 58
