CLICK

Selects Click audio output, (default audio output) the audio

output is a 'Geiger' type click which increases in frequency

as the signal strength increases. This is used mainly when

pinpointing the location of a target as the click rate will

usually be at its maximum closest to the target

Note 1 During start up in the 'Set Tx power' menu this button

(click) sets the maximum TX power to 20mW (EU low power

setting).

NITIAL

ODE

This is the default mode for power control. The user

manually sets the transmitter output power level using the

rotary Power Control (9) from L up to the maximum power

set during startup.

DSP M

ODE

In DSP mode due to the continually controlled power output

level the battery life is optimised, this can extend battery life

considerably compared with manual mode.

In this mode a software algorithm is used to control the

transmitter output power. As the antenna approaches a target

non-linear junction the transmitter power is reduced. This

avoids overloading the target junction with radio energy

which can give rise to false indications. When the antenna

is moved away from the target junction the power output is

increased by the controlling algorithm.

In DSP mode the changes in power level are transparent to

the user as the received signal indication levels (Geiger click,

bar graph, front panel display) will continue to rise and fall

as the antenna gets closer to or moves away from the target.

When in DSP mode the rotary power output control (9) can

be used to reduce the transmitter power below the maximum

set during startup to a minimum of power level 2.

EARCH

ECHNIQUE

It is strongly recommended that users have electronic devices

concealed for them by a colleague in order to gain practical

experience under controlled conditions.

Some users prefer to carry the SuperBroom with the carrying

strap around the neck rather than over the shoulder so that

the front panel display is easily seen.
