TENStem eco basic

Intended use The TENStem eco basic has been designed for the generation of the transcutaneous electrical nerve and muscle stimulation and may not be used for any other purposes.

Safety instruction Please read the operating instructions carefully before using the device! Only use the device with original accessories. Keep the device away from water or other liquids. Do not drop the device, do not use it inappropriately or expose it to extreme temperatures or high humidity (not less than 10 °C or more than 40 °C or a relative humidity of more than 90 %). Do not use the device if it is not working properly or if it has been damaged in any way. Be careful when using the device near or on children. Always store the device in its case to protect it from damage and dust. Caution! Patients with medical implants (e.g. cardiac pacemakers) should consult their doctor before using the TENStem eco basic. The TENStem eco basic may only be connected to one person at any one time. Long treatment sessions are subject to limited periods of time. Do not extend the treatment time of the fixed programs. After a treatment session wait for several hours before using the TENS unit again. Warning! The simultaneous use with a high frequency surgical unit can cause burns underneath the electrodes. The application of the TENS unit close to a shortwave or microwave device can cause variations in the output values of the TENS. In addition, portable or mobile high frequency communication devices may affect the operation of electrical medical devices. The size of the electrodes should not be less than 2 cm².

Operating the TENStem eco basic Starting the device Insert the batteries into the battery compartment (no. 5). Please also read the chapter “Battery change” for more information. All symbols appear automatically on the display. An acoustic signal indicates that the unit is ready for use. Connecting electrodes and cables First connect the 2 mm diameter male connectors of the cables (red and white connector on each cable) to the black female connectors of the electrodes (always 2 electrodes per cable). Connecting the cables to the TENStem eco basic Connect the white plug at the other end of the cable to the sockets on the upper front face of the TENStem eco basic (no. 6). You may use the device with one or two cables depending on the therapy. Switching ON the TENStem eco basic Press to switch ON the TENStem eco basic. A double beep sounds. The display indicates the selected program, the therapy time, the frequency, the pulse width and the intensity. Program

ON/OFF, Stop Selecting a program

Press P until you have selected the program of your choice. Once you have reached P15 you will return to P1. Starting the stimulation / setting the intensities Press the left key to increase the intensity of channel 1. Press the right key to increase the intensity of channel 2. Press the left key to reduce the intensity of channel 1. Press the right key to reduce the intensity of channel 2. It is not possible to adjust the intensity of both channels at the same time.

Stopping the stimulation The stimulation stops automatically at the end of each program. You can stop the stimulation manually at any time by pressing the P key or the key. Switching OFF the device Press the key to switch OFF the device. A single beep sounds. The TENStem eco basic switches OFF automatically after 2 minutes if no key pressed.

Setting date and time (From series C) Before you can use the memory query mode you need to set the date and time. Pressing and holding the E key for about 3 seconds leads you to the date/time mode. In date/time mode the LCD shows two figures: The left figure indicates the date, the right figure indicates the time. Pressing the left key increases the date by one day (max. 30). Pressing the left key decreases the date by one day (min. 1). Pressing the right key increases the time by one hour (max. 23). Pressing the right key decreases the time by one hour (min. 0). Press the key to save all parameters and to leave the date/time mode again. Date and time are continuously updated. The TENStem eco basic switches OFF automatically after two minutes if no key is pressed. In this case none of the adjusted parameters are saved.

Memory query mode (From series C) First set the date and time (see above). The memory query mode is used to read out saved therapy data from patients. By pressing and holding the left and E key for about 3 seconds you enter the memory query mode. If no values are saved, the display shows “null” for about 2 seconds and the device returns to standby mode automatically. If you have saved therapy data, the display shows the parameters of the last therapy session as shown below: -

Used program = P01 Frequency = 100 Hz Pulse width = 200 µs Therapy duration = 0 min 44 s Day of therapy = 5 (fifth day) Therapy session no. = 3

You can save up to 90 therapy sessions respectively the first 3 of each day. With the left key you can return to the values of the previous day (until you reach the first recorded day). The left key lets you proceed to the next day (until you reach the current day). The right key brings you to the parameters of the last therapy session of the respective day (until you reach the first session of the respective day). The right key shows you the parameters of the next therapy session (until you reach the last session of the respective day).

Resetting the memory Pressing and holding the E button for about 5 seconds will delete all saved data. The display shows “Clr” for about 2 seconds and the device can be used for stimulation again. The TENStem eco basic switches OFF automatically after two minutes if no key is pressed.

Battery change If the battery voltage is less than 3.7 V, the battery symbol appears in the display and it is necessary to insert in 4 new 1.5 V batteries (AAA, e.g. LR03). To change batteries: - Switch OFF the device. - Open the battery compartment on the back side of the device by sliding out the cover. - Remove the old batteries. - Insert the new batteries (check polarity). - Close the battery compartment. If you do not use the device for a longer period of time, always remove the batteries. In case you use rechargeable batteries, please follow the instructions of the charging unit. Please dispose old batteries properly!

This program could be called the last recourse if none of the other programs give analgesic effect. However, because of the high frequency this �� program is often felt as less pleasant. Furthermore, high frequency stimulation needs more battery power. Intensity ��

Electrode placement for dynamic stimulation (P10, P11, P15) The stimulation is not administered simultaneously on both channels. The current flowes from one electrode to the other just like a wave undulating on the body. This kind of stimulation is far more comfortable than traditional neuro-muscular stimulation. Dynamic stimulation can be used with high frequency parameters for a improved pain control or with low frequency parameters for optimized muscle stimulation. This treatment method also has an enhanced effect on lymphatic drainage stimulation. The placement of electrodes for dynamic stimulation depends on the direction of stimulation (rising/falling stimulation or sideways stimulation) Rising or falling stimulation for back or legs
