Introduction
Thank youfor purchasing the PM-770.PM-770 isa singleoutputchannelTENS
device. Itis intended for pain relief inthe knee.TENSstands for Transcutaneous
Electrical NerveStimulation is recognized asa safe and highlyeffectivemethod of
relievingpain.TENS isnow regularlyrecommended by doctors,physiotherapists and
pharmaciststhroughout the world.Before using, pleaseread allthe instructions in this
user manualcarefully and keep it safe for future.
How doesTENSwork?
PM-770works by passingharmless electrical signalsinto the bodyfrom the support
wrap. This relieves pain intwo ways:
• Firstly, it blocks the body'spainsignals which are normallytransmittedfrom the area of
damagethrough the nervefibres tothe brain - TENSinterruptsthesepainsignals.
• Secondly,TENSstimulates the body'sproduction of endorphins - itsown natural
painkillers.
