It does not represent how much RF the device emits. All devices are tested at theirhighest value in strict laboratory settings. But when in operation, the SAR of a device can besubstantially less than the level reported to Industry Canada. This is because of a variety offactors including its proximity to a base station antenna, design and other factors. What isimportant to remember is that each device meets strict federal guidelines. Variations in SARsdo not represent a variation in safety.
