| The<br>actions<br>taken to<br>mitigate<br>the risks | -Temperature is controlled by temperature sensor |
| | -If the temperature control system is bad, power turns OFF by<br>bimetal. |
| | -Temperature control of lower heat is designed to make lower<br>temperature than actual temperature. (Checking temperature<br>variation) |
| | -If the Hall effect sensor and Photo sensor are not connected, error<br>occurs and system stops. |
| | -System turns OFF when the remote control and 2D-GX is<br>separated. |
| | -Motor should go to head side, and up/down position should be<br>down side when the device is off. Device does not turn off if it is<br>not initialized. |

# J. Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence is as follows:

The Model 2D-GX thermal massage bed has been tested to and meets the requirements of the following standards.

IEC60601-1 :88+A1:91+A2:95 Medical electrical equipment-Part1:General requirements for safety

IEC 60601-2-38:1996+A1:1999Medical electrical equipment Part2: Particular requirements for the safety of electrically operated hospital beds

IEC60601-1-2:2007 Medical electrical equipment-Part1-2: General requirements for basic safety and essential performance-Collateral standard: Electromagnetic compatibility-Requirements and tests.

## K. Discussion of Clinical Tests Performed:

The performance test was performed in order to show the safety of the device and to show the device can make the therapeutic range (40-45℃) from the users' skin surface temperature. By testing 30℃ and 65℃ (minimum and maximum of the device temperature setting) for 5 people, the device is able to elevate skin surface temperature from normal baseline temperature to the therapeutic range (40~~45℃) when the device activated by 65℃ setting. And for 30℃ setting, device has not been shown to provide a therapeutic effect and is indicated for comfort warming only.

## L. Conclusion:

The non-clinical testing and clinical study results demonstrate that the 2D-GX, thermal massage bed is safe, accurate. It also demonstrates that the 2D-GX, thermal massage bed is substantially equivalent to the predicate device, 2D-LX, currently sold on the U.S. market.
