Check after Cleaning
Confirm that the cuff bladder is correctly inserted inside the cuff
cloth. If it is not correctly inserted, damage or explosion may
occur during inflation.
Cleaning the recorder
Wipe the dirt and dust on the exterior of the recorder using soft dry
cloth. Clean blood, medicines, etc. using a cloth moistened with mild
detergent.
Cleaning the cuff
Do not squeeze the cuff and cuff cover when washing. Submerge
the cuff and cuff cover in a mild detergent and wash so that the cloth
avoids damage. Rinse with water.
The cuff and cuff cover are consumable goods.
When measurement error occurs frequently and measurement
cannot be performed, replace the cuff and cuff cover with new ones.
Refer to "10. Optional Items (requiring order)" for information on
ordering options.
