Scope of Delivery
Frequency detector, Operating instructions,
9V monobloc battery
Unpacking the Equipment
Remove the packaging from all components
and check that the delivery is complete.
Function
The frequency detector shows in a simple way
whether an interference signal has been
detected in the corresponding frequency band.
The device detects 433,92 MHz and 868,3
MHz amplitude (AM, ASK, OOK) and
frequency-modulated (FM, FSK) signals.
Trends can be clearly recognized via the quasi
analog LED display. In this way the source of
the interference can be more quickly localized.
Start-Up
Set the ON/OFF switch to the corresponding
frequency (433 MHz oder 868 MHz). LED1
glows indicating that the unit is ready for
operation (see fig. 1).
Depending on the intensity, existing 433 / 868
MHz frequency signals are then indicated in
the measuring value display by LEDs 2 – 10
Inserting the 9V Monobloc Battery
If after switching the unit on, LED1 (see fig. 1)
glows weakly or not at all, then change the
battery.
Changing the battery:
•Grasp the battery compartment cover at
both sides A and slide in the direction of
arrow B (see fig. 2).
•Insert a new battery. Make sure the poling
is correct (observe symbols + and – in the
battery compartment). Use 9 V monobloc
batteries only (see fig. 3).
•Slide battery compartment cover back on.
Caution! Keep batteries out of reach of
children!
Cleaning
•Wipe the casing carefully with a damp,
fluff-free cloth.
•Do not use cleansing agents containing
organic solvents. These pose a health risk
and may damage the surface of the
casing.
Disposal
Waste electrical products and batteries
should not be disposed of with household
waste!
Dispose of the waste product via a
collection point for electronic scrap
or via your specialist dealer.
Dispose of used batteries in a
recycling bin for batteries or via
the specialist trade.
Put the packaging material into the
recycling bins for cardboard, paper
and plastics.
