1. Introduction
Thank you for choosing the MLAY RF02 RF Radio Frequency and EMS Beauty Device. This advanced instrument combines Radio Frequency (RF) and Electrical Muscle Stimulation (EMS) technologies to provide comprehensive skin care, targeting various concerns such as skin tightening, wrinkle reduction, and lifting effects for both face and body. Please read this manual thoroughly before use to ensure safe and effective operation.
Key Features:
- Multipolar Deep Radio Frequency: Heat energy penetrates deep into the dermis to promote metabolism and stimulate collagen formation.
- RF+EMS Mode: Offers a dual beauty effect for enhanced skin rejuvenation.
- EMS Electromyography: Stimulates facial muscles for lifting, face thinning, and wrinkle reduction.
- Innovative Circular Bipolar RF Technology: Ensures effective and targeted treatment.
- Comprehensive Skin Benefits: Lifts and firms, smooths and tenders skin, reduces fine lines, and shrinks pores.
- Dual Probes: Includes both a body probe and a face probe for versatile application and improved skin care efficiency.
2. Safety Precautions
- Do not use this instrument on dry skin surfaces. Always apply a matching ice refreshing nourishing repair essence or conductive gel before use.
- Avoid using the device in the same area for prolonged periods to prevent burns or overheating.
- If you experience any discomfort or feeling of overheating during care, immediately reduce the gear level or stop use.
- Ensure the device is clean before and after each use.
- Keep out of reach of children.
- Do not attempt to disassemble or repair the device yourself.
- Consult a physician before use if you have any underlying skin conditions, medical implants, or are pregnant.

6. Operating Instructions
- Select Mode: Short press the on/off button to switch between RF and EMS modes.
- Adjust Gear: Press the gear toggle keys to select the appropriate intensity level for your treatment.
- Apply Essence/Gel: Apply a generous amount of matching ice refreshing nourishing repair essence or a suitable conductive gel to the treatment area. This is crucial for effective and safe operation.
- Apply Device: Place the probe gently on the skin.
- Treatment Technique: Operate the device using spiral circling techniques. Move the probe continuously to avoid concentrating heat in one area.
- Monitor Heat: If you feel any overheating, immediately reduce the gear level.
Facial Application:
During facial manipulation, a comfortable warmth is a good experience. The cool nourishing and repairing essence is easily absorbed by the skin. Pay attention to supplement the essence to keep the probe operating smoothly.

Body Application:
The operation methods for body parts are consistent with facial techniques. For example, when treating the arm, divide it into two parts (a) and (b). Start from the left outer arm, circle up, and then gently pull down to the origin. Repeat the operation 3-4 times according to the time. The inner arm is operated in the same way. All other body parts can be operated by partial spiral winding.

Understanding RF and EMS:
RF Radio Technique: By touching the skin with the probe, RF transforms electric energy into heat energy, penetrating into the dermis to raise temperature, accelerate the temperature of the dermis and subcutaneous tissue, stimulate the formation of collagen, and achieve multiple cosmetic effects such as lightening skin, improving dark yellow skin, and keeping muscles smooth.

EMS Electrical Stimulation: Electromyographic stimulation exercises facial muscles through electrical stimulation, contraction, and relaxation of muscles, to achieve the effect of pulling and slimming the face and reducing wrinkles, particularly in areas like nasolabial folds.

7. Maintenance
- Cleaning: After each use, long press the on/off button to shut down the machine. Disconnect the power supply. Use a soft, dust-free cotton cloth to gently wipe the probes and the main device. Do not use abrasive cleaners or immerse the device in water.
- Storage: Store the device in a cool, dry place, away from direct sunlight and moisture. Keep it in its original packaging or a protective case when not in use.
- Cable Care: Ensure the power cable and probe cables are not twisted or kinked during storage to prevent damage.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on | Power cable not connected properly; Power outlet issue; Device malfunction. | Ensure power cable is securely connected. Try a different power outlet. If problem persists, contact customer support. |
| No sensation or weak sensation during use | Insufficient conductive gel; Low intensity setting; Probe not in full contact with skin. | Apply more conductive gel. Increase the intensity level. Ensure the probe is in full contact with the skin. |
| Skin feels overheated or burning sensation | Intensity setting too high; Probe held stationary for too long; Insufficient conductive gel. | Immediately reduce the intensity level. Keep the probe moving continuously. Apply more conductive gel. If discomfort continues, stop use. |
| Display screen not working | Device malfunction. | Try restarting the device. If problem persists, contact customer support. |
