Safety Notes
Shutdown when defective
WCDMA Options Version 6.20

Shutdown when defective
In the following cases, safe operation is very likely to be no longer possible:
– if the test set exhibits visible damage,
– if the test set will no longer work,
– after a longish period of storage under the wrong conditions (see data
sheet),
– following transport under adverse conditions.
If you suspect that it is unsafe to continue operating the 4400, shut it down
immediately and pull out all power connectors.
Secure the test set in such way that nobody else can start it up again, in order
to protect any third party.
Get in touch with your nearest Willtek service center.
High voltages after power disconnect
High and dangerous voltages can still be present in the instrument even when
it is being powered from a battery.
Use proper fuses
Defective fuses must be replaced with fuses of identical specifications.
Never patch fuses or short the fuse holder.
