Chapter 10: Maintenance and Cleaning
10.1.3 Maintenance of Transducers
Keep the transducers in a dry environment, where the temperature should be lower than +45°C
(+113 °F).
Gel must be wiped from the US transducer after use. These precautions will prolong the life of
the transducer.
Avoid contacting the transducers with hard or sharp objects. Although transducers are designed
for durability, they should be handled with care. Rough handling could damage the cover,
piezoelectric crystals and mechanical movement.
Do not excessively flex the cables.
10.1.4 Storage of Recorder Paper
The thermosensitive recorder paper is not intended to be used as a long-term storage medium. We
recommend you save the monitoring data to another medium.
When storing recorder paper (including used paper with traces):
Do not store in plastic envelopes.
Do not leave exposed to direct sunlight or ultraviolet light.
Do not exceed a storage temperature of +40 ºC (+104 ºF).
Do not exceed a relative humidity of 80%.
Storage conditions outside these limits may distort the paper and adversely affect the accuracy of
grid lines or make the trace unreadable.
10.1.5 Maintenance of Recorder
WARNING
Switch off the monitor and remove the power cord prior to recorder cleaning.
Check to see if the paper sensor is covered with dust. If it is dirty, gently wipe it clean with a dry
cloth or a cotton swab.
