MEMORY FUNCTION
Measured result is stored in either M1 or M2. Each of two memory banks can hold up to 30 results and their average. When the number of
measurements exceeds 30, the oldest data will be deleted to record new data. You may decide which bank to store your measurement results to
avoid data mixture with someone else's, or may use two banks to save data measured in the morning and evening separately.

TECHNICAL DESCRIPTION
DS-500 complies with the EMC, electromagnetic compatibility, standard, IEC60601-1-2.
Refer to the tables below for speci c information regarding compliance to the standard.
DS-500, as a medical electrical equipment, needs special precautions regarding EMC and needs to be installed and put into service according to the EMC information
provided below.
Portable and mobile RF communications equipments can a ect the device.
e use of accessories other than those speci ed in this manual may result in increased emissions or decreased immunity of the device.
DS-500 should not be used adjacent to or stacked with other equipment.

Electromagnetic environment - guidance
DS-500 uses RF energy only for its internal function.
erefore, its RF emissions are very low
and are not likely to cause any interference in nearby electronic equipment.
DS-500 is suitable for use in all establishments, including domestic establishments and those
directly connected to the public low-voltage power supply network that supplies buildings used
for domestic purposes.
e customer or the user of DS-500 should assure that it is used in such an environment.
