1. FOREWORD Introduction The device ZZACOMBO is a dual channel output TENS, EMS, and MASSAGE stimulator. Before using, please read the instruction manual. The COMBO stimulator belongs to the group of electrical stimulation systems. It has three basic functions: TENS (Transcutaneous Electrical Nerve Stimulation), EMS (Electronic Muscle Stimulation), and MASSAGE.

1.2 Medical Background 1.2.1 About Pain Pain is an important signal in the human body warning system. It reminds us that something is wrong without which abnormal conditions may go undetected, causing damage or injury to vital parts of our bodies. Even though pain is a necessary warning signal of trauma or malfunction in the body, nature may have gone too far in its design.
1.2.3 What Is EMS? Electrical Muscle Stimulation is an internationally accepted and proven way of treating muscular injuries. It works by sending electronic pulses to the muscle needing treatment that causes the muscle to exercise passively. It is a product deriving from the square waveform, originally invented by John Faraday in 1831.

2.2.2 Warning 1) The long-term effect electrical stimulation is unknown. Electrical stimulation devices do not have any curative value. 2) This device should only be used under the continued supervision of a licensed medical practitioner. 3) Electrical stimulation is not effective for central origin pain such as headache.
Page 9
11) Stimulation should not take place while the user is connected to high-frequency surgical equipment, it may cause burn injuries on the skin under the electrodes, as well as problems with the stimulator. 12) Do not use the stimulator in the vicinity of shortwave or microwave therapy equipment, since this may affect the output power of the stimulator.

5. OPERATING INSTRUCTION 5.1 Battery 5.1.1 Check/Replace Batteries Open the battery cover and insert three batteries (type AAA) into the battery compartment. Make sure you are installing the batteries properly. Be sure to place the batteries according to the markings of positive terminal (+) and negative terminal (-) in the battery compartment of the device.
Page 20
5.2 Connect Electrode Pads to Electrode Wires Insert the electrode wires connector into the electrode connector. Make sure they are properly connected to ensure good performance. Please refer to the picture below. Caution Always use the electrode pads that comply with the requirements of the IEC/EN60601-1, ISO10993-1/-5/-10 and IEC/ EN60601-1-2, as well as CE and FDA 510(K) regulation.

5.4 Electrode 5.4.1 Electrode Options The electrodes should be routinely replaced when they start to lose their adhesiveness. If you are unsure of your electrode adhesive properties, please order new replacement electrodes. Replacing electrodes should be reordered under the advice of your physician or the device manufacturer to ensure proper quality.
Page 22
5.4.3 Electrode Placement The placement of electrodes can be one of the most important factors in achieving successful therapy. Please consult a physician to try the various styles of electrode placement to find which method best fits the needs of the individual patient. Every patient is differing from the responds to electrical stimulation, and their needs may vary from the conventional settings suggested here.
6. INSTRUCTIONS FOR USE 6.1 Turn On When using it for the first time, open the battery cover and load three new batteries (Please review Section 5.1.1 for the operating steps and schematic diagram). Press the [ON/OFF/M] button to turn the device on; the LCD will be lit.
Page 24
6.3 Select Treatment Program Based on your need, press [P] button to select the treatment program. The LCD displays as follows: 6.4 Set Program Parameter Press and hold [P] button to enter the setting mode. 1) In the program p1 to p6 of the TENS mode and the program p1 to p5 of the EMS mode, press [+]/[-] button to adjust treatment time.
Page 26
6.5 Start Treatment Press the [+] button of CH1 to increase the channel 1 intensity press the [+] button of CH2 to increase the channel 2 intensity. The LCD displays as follows: 6.6 Adjust the Output Intensity Place the electrodes on the body parts. Press the [+] button to increase output intensity.
Page 27
Caution If you feel or become uncomfortable, reduce the stimulation intensity to a more comfortable level and consult with your medical practitioner if problems persist. 6.7 Stop the Treatment and Turn Off the Device Press the [ON/OFF/M] button to stop treatment during the treating mode.

7. CLEANING AND MAINTENANCE Fully comply with the following necessary daily maintenance requirements to make sure the device is intact and guarantee its long-term performance and safety. 7.1 Cleaning and Caring for the Device 7.1.1 Pull the electrodes out of the stimulator; clean the device with a soft, slightly damp cloth.
Page 30
Use only the electrode placements and stimulation settings prescribed by your physician or therapist. 7.3.2 It is recommended to use electrodes measuring 50 x 50mm that are manufactured by BodyMed ® 7.3.3 Inspect your electrodes before every use. Replace electrodes if needed.
Page 31
To use these electrodes: 1) Attach the electrode to the lead wire. 2) Remove the protective backing from the electrode surface. Do not throw away the protective backing because it can be reused after the treatment session has been completed. 3) Place the tacky surface to the prescribed skin area by pressing the electrode firmly to the skin.
7.4 Cleaning the Electrodes Cords: Clean the electrode cords by wiping them with damp cloth. Coating them lightly with talcum powder will reduce tangles and prolong the life. 8. TROUBLESHOOTING Should any malfunction occur while using the device, check whether the parameters are set appropriately for therapy, and adjust the control correctly.
9. STORAGE 9.1 Storing the Electrode Pads and Lead Wires 1. Turn the device off and remove the lead wires from the unit. 2. Remove the electrodes from your body and disconnect the lead wires from the electrodes. 3. Place the electrodes onto the plastic film and then store in the sealed package.
