Recommended mounting of
TXP(H) transmitter
The TXPH transmitter is supplied with a wire belt-clip allowing the transmitter to be
attached to a belt or waist line of trouser or skirt. This is to ensure that the
transmitter is orientated in a vertical plane at the correct height and separation
from the body.
Placing the transmitter in a pocket of a shirt or trousers is not allowed in order to
avoid that the separation distance between the device, antenna, and the body of the
user will be less than the separation distance which is guaranteed by using the belt
clip.
Batteries
Upon finishing with any used batteries please dispose of them as special waste. In
order to protect the environment, only dispose of exhausted batteries.
