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.

TXP(H) Frequency ranges supplied for use in USA

The TXP transmitter can tune over a switching bandwidth of up to 40MHz. The

frequency ranges are listed below:

470.1-495.9MHz

496.1-523.9MHz
