BY STEP USE and make sure that the electrodes are correctly placed Slightly change the position of the electrodes THE STIMULATION FEELS UNPLEASANT The skin is irritated For advice on skin care see chapter PRECAUTIONARY MEASURE The electrodes begin to lose their stickiness and do not stick properly to the skin Moisten the adhesive surface with a few drops of water before placing on the skin The electrodes are worn out and need to be replaced There is insufficient electrode gel on the carbon rubber electrodes Slightly change the position of the electrodes THE STIMULATION FEELS WEAK OR NOT AT ALL Check if the batteries need to be replaced see chapter REPLACEMENT OF BATTERIES Electrodes are too old and need replacement THE BROKEN CIRCUIT SYMBOL IS SHOWN ON THE DISPLAY SYMBOL The broken circuit symbol indicates that the resistance is too high or that a cable is broken 7M Atoo high resistance can be caused by a bad connection between the electrodes and your skin or that the electrodes need to be replaced A cable breakage can be checked by pressing the cable s pins against one another while increasing the amplitude for the corresponding channel to 11 mA If the amplitude now drops to 0 0 mA and X starts flashing the cable needs to be replaced Note Never increase the amplitude above 20 mA when you check for cable breaks since this can damage the stimulator THE STIMULATOR IS NOT WORKING
6. Relief programs impulses are sent through the nerves to block the pain impulses Pain Relief is usually most efficient during stimulation but the effect can also last after the program has finis hed It also increases the circulation The Pain Relief programs do not always treat the cause of pain If the pain persists seek medical advice WHEN AND HOW SHOULD USE TENS The programs in the CEFAR PRIMO PRO can be used on any occasion when Pain Relief or Muscle Relaxation is needed All the programs can be used as often as required Guidelines for using the preset treatment programs with indication examples suggested electrode placements and recommended treat ment time are included in this manual 3 PRECAUTIONARY MEASURES Inspect the equipment prior to use Use the stimulator only as stated in the operating instructions Only Cefar accessories should be used with the stimulator WARNING People with implanted electronic equipment such as pacemakers and intracardiac defibrillators must not be treated with TENS Pregnant women should not be treated with TENS during the first trimester 12 weeks Due to the location of the carotid arteries and the carotid bodies do not stimulate the front or sides of the neck since a drop in blood pressure can occur 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

10. ENT OF BATTERIES battery symbol is shown on the display when the batteries are almost empty 8 As long as the stimulator is working normally you can continue the treatment When stimulation feels weaker than usual or the stimulator turns off it is time to replace the batteries If the stimulator is not used for some time approximately 3 months the batteries should be removed from the stimulator The stimulator operates on either two non rechargeable 1 5 V AA batteries or two rechargeable 1 2 V AA batteries recharged in a separate charger The endurance of the batteries depends on the amplitude and number of channels activated during a pro gram being used For example if you use one channel at P1 with an amplitude of 30 mA the non recharge able batteries last approximately 11 hours and rechargeable 7 hours REPLACING THE BATTERIES Turn off the stimulator Locate the battery compartment on the back of the stimulator Remove the battery cover by pressing the mark at the top firmly and sliding the cover downwards Remove the batteries oF N Insert the new batteries correctly according to the polarity markings and inside the battery com partment see picture 6 Replace the battery cover 7 Dispose of the exhausted batteries in accordance with local and national regulations NOTE Non rechargeable batteries may not be charged due to the risk of explosion 7 PROGRAMS PRESET PROGRAMS
