The Low-Frequency Therapy Device KLM808 is a physiotherapy instrument that utilizes low-frequency electrical stimulation to relieve pain, improve muscle function, and promote overall muscular health. By delivering controlled electrical impulses, the device helps stimulate nerves and muscles to achieve therapeutic effects.

Therapy Application

Treatment Program Selection

Select an appropriate treatment program based on the user’s needs. Place the electrodes on the correct body area; conductive gel or a lubricant may be used to improve contact.

Output Intensity Adjustment

Adjust the output intensity according to the user’s comfort level. If the stimulation feels weak during treatment, the intensity may be increased gradually.

Output Rhythm Adjustment

During treatment, users may adjust the output rhythm (treatment time and rest time) to achieve the most comfortable sensation.

Usage Time Limitation

The total daily usage time should not exceed 90 minutes. Proper hygiene and cleanliness of the device should be maintained.

Indications and Therapeutic Effects

Massage

Improves tissue oxygenation, restores muscle contraction function, promotes blood circulation, relaxes the body and mind, reduces mental stress, alleviates tissue fatigue, improves sleep quality, and enhances overall quality of life.

Lower Back Pain

Relieves pain through the release of endorphin-like substances, increases blood flow, and is suitable for pain relief in chronic lower back pain.

Dysmenorrhea

Promotes blood circulation, increases local blood flow, helps inhibit abnormal uterine contractions, and relieves spasmodic pain caused by ischemia of uterine smooth muscles.

Muscle Training

Muscle Pain, Sports Bruises, Strains, and Sprains

Improves muscle contraction quality, restores or enhances cellular exchange, increases muscle fiber diameter, improves muscle endurance, prevents muscle atrophy and overuse injuries, strengthens muscles, improves muscle shape, and promotes muscle regeneration.

Slimming and Weight Loss

Stimulates muscles, improves oxygen absorption capacity, enhances endurance performance, improves overall physical health, reduces excess body fat, and increases compound amine levels in the blood.

Tapping and Kneading Modes

Relieves pain caused by nerve conduction blockage or poor blood circulation, reduces muscle tension, and relaxes muscles. Suitable for sports strains, sprains, elbow pain, cervical spine pain, and various other pain conditions.

Battery Usage and Replacement

Low Battery Indicator

When the battery symbol appears on the display, the power voltage is low and the batteries must be replaced.

Battery Specification

This device uses three AAA (1.5V) batteries. Do not use batteries of other specifications. Alkaline batteries are recommended.

Operating Modes

Power-Off Mode

No display on the LCD screen.

Power-On Mode

Allows time setting, treatment program selection, and intensity adjustment.

Treatment Mode

Treatment begins, the timer counts down, and therapy parameters are output.

Pause Mode

Temporarily pauses treatment and can return to treatment mode.

Operating Instructions

Operations in Power-Off Mode

Press the power button to enter standby mode.

Operations in Power-On Mode

• Power Off: Press the power button to turn off the device.
• Set Treatment Time: Press the [E] key to set treatment time (range: 5–90 minutes, adjustable in 5-minute increments).
• Select Treatment Program: Press the [P] key to choose the desired program.
• Adjust Treatment Intensity: Press [CH1+] or [CH2+] to increase intensity. Maximum intensity level is 50.

Operations in Treatment Mode

• Adjust Intensity:
• Press [CH1+] / [CH2+] to increase intensity
• Press [CH1-] / [CH2-] to decrease intensity
• When intensity is reduced to 0, the device returns to standby mode
• Key Lock / Unlock:
• If no button is pressed for 15 seconds, the keypad will automatically lock. Only the [CH1-] or [CH2-] keys can unlock it.

• Electrode Detection:
  If poor electrode contact is detected, the corresponding channel will automatically reset to zero and stop output.

• End of Treatment:
  When the countdown finishes, all channels are turned off and the device returns to power-on mode.

• Pause:
  Press the [P] key to pause treatment; press [P] again to resume.

Precautions

• After use or cleaning, do not expose electrodes to environments prone to bacterial growth. Store electrodes in a sealed bag in a clean, dry, and cool place.
• If electrode adhesion weakens, lightly moisten with clean water to restore partial stickiness. Replace electrodes once aged.
• If skin allergy, redness, swelling, or itching occurs after replacing electrodes, discontinue use immediately as it may indicate material incompatibility.
• Electrodes are for personal use only. Do not share electrodes to avoid cross-infection.
• Do not exceed 90 minutes of treatment per day. Excessive use may cause skin irritation or burns. Mild soreness after initial use is normal and indicates therapeutic effectiveness; it usually subsides after several days.
