SuperBroom Plus TA – Operating Manual

Non-linear junctions can also be formed when two metal

objects are in contact due to complex chemical behaviour at

the junction of the objects.

The signal generated by SuperBroom is a spectrally pure

radio signal within the frequency band of 869.4 – 869.65

MHz ( There are 19 frequency channels of which only the

10 optimum channels, selected during SuperBrooms's start

up self-check procedure, are used at any time). Any non-

linear junction within range re-radiates the radio energy at

harmonic frequencies of the incident signal. In this case the

frequencies produced are:

1738.825 – 1739.275 MHz - usually termed the 'second

harmonic'

2608.2375 – 2608.9125 MHz - usually termed the 'third

harmonic'

and so on. A complete frequency plan is given in appendix

The nature of the non-linear junctions within electronic

components is such that the strongest harmonic produced

is usually the second harmonic, with the third harmonic

usually appreciably weaker. Other harmonics are usually

very weak.

In contrast to this the nature of the non-linear junctions

between metal objects are such that the strongest harmonic

produced is usually the third harmonic, with the second

harmonic usually appreciably weaker (but may be roughly

equal in some situations). Other harmonics are usually very

weak.

Spent battery packs should be returned to Audiotel

International Ltd.Do not use the AC Power Lead or AC/DC

Adaptor if:

■ The AC Power Lead cable or its plugs become frayed

or otherwise damaged

■ The AC/DC Adaptor casing is cracked or otherwise

damaged

■ The AC Power Lead or AC/DC Adaptor are exposed to

rain, liquids or excessive moisture

The AC Adaptor should only be used in controlled offi ce

environments with a maximum ambient temperature of 35º

Centigrade and Relative Humidity of 85%.

Do not use the SuperBroom if:

■ The SuperBroom unit is exposed to rain or other

excess moisture

■ The unit has been damaged

■ You suspect the unit requires servicing

You should take the following precautions.

■ Do not point the antenna at a person's eyes or head

■ Do not leave the antenna in close proximity to any

part of the body for prolonged periods.

■ Do not use near infl ammable fl uids or explosives or

in any area where the use of radio communications

equipment is prohibited

■ Do not use in close proximity to any person fi tted with

a heart pacemaker or any other life support system

■ Switch off SuperBroom when not in use, this

minimises exposure to RF energy and prolongs battery

life.

SuperBroom may interfere with operation of some electrical

equipment.
