General rules
Check arriving pallets on transport damage!
Don’t use transducers from damaged pallets.
Use first in first out!
The transducers always should be stored in the original packaging only!
Don’t touch the membrane.
In case the transducer is mounted into assemblies where an ultrasonic welding process
will be used after the transducer is already in place, the function of the transducer can be
damaged due to the USW!
Keep transducers away from magnetic regions! Avoid humid and hot air! Prevent
transducers from dropping on the floor because of the risk of damage to spring contacts!

Transportation
First off all, beware that the transport unit is fragile and handle it with care.
Check arriving pallets on transport damage and remove the plastic cover carefully.
In each situation keep the delivery unit dry.
Use the delivery units according the first in -first out principle in your warehouse.
If pallets should be stored consider that each transport unit has to stand separate.
To keep the effect of magnetism as low as possible, notice the special form to pile single
boxes on a pallet.
