2. Attaching Massage Heads:

3. Heat and Cold Mode Operation:
The device features an aluminum plate for both heating and cooling.
- Heat Mode: The aluminum plate heats up in 3 seconds, with 4 adjustable levels ranging from 102-113 °F (39-45 °C). Heat compression activates muscles and boosts blood circulation.
- Cold Mode: The aluminum plate cools down in 3 seconds, with 4 adjustable levels ranging from 46-57 °F (8-14 °C). Cold compression contracts muscles and reduces blood circulation, alleviating swelling and soreness.
