# Analysis 5:

The subject device maximum IR output energy density ranges from a lower limit of 0.17 W/cm² to an upper limit of 0.63 W/cm². The upper limit of the subject device (0.63 W/cm²) falls within the range of the predicate device's upper limit, while the lower limit (0.17 W/cm²) is similar to that of predicate device 2 (0.21 W/cm²); the slight difference of 0.04 W/cm² falls within the margin of error(±20%) and does not impact the safety or effectiveness of the subject device. Therefore, the difference in maximum IR output energy density does not affect the safety or effectiveness of the subject device.

# Analysis 6:

Compared with predicate device, although there is a difference but the reasons are as follows. Although the "Vacuum" of the subject device is different than in the predicate device, the high "Vacuum" within the range of the predicate device's.

Therefore the difference doesn't impact essential performance, basic safety or substantial equivalence.

# Analysis 7:

The lower and upper limits for the IR Treatment Area of the subject device are 634mm² and 3433mm², respectively. The upper limit of the subject device (3433 mm²) is similar to that of predicate device 1, and the lower limit (634 mm²) falls within the range of predicate device 2. Therefore, the differences in IR Treatment Area do not affect the safety and effectiveness of the subject device.

# Analysis 8:

Not identical. That difference does not generate a safety and effectiveness issue.

# Analysis 9:

Not identical. That difference does not generate a safety and effectiveness issue.

# Analysis 10:

Not identical. The subject device provides a different "Power supply" than the predicate device. Electrical safety testing and EMC testing have been performed for the subject device. Risk analysis have also been performed to support proof of safety
