The IR-1S Micro can be used hanging on a strap around the neck. Thread the thin loop of
the neck strap through the attachment loop on the transmitter. Adjust the length of the neck

strap can be pulled out eg. if the transmitter gets caught on something. Never make knots in
the neck strap!

Do not use any disinfectant except surgical spirit, Chlorhexidine or ethyl
alcohol.
These liquids are inflammable, handle with care!
