On / Off Switch; Backlighting; Replacing The Battery; Calibration - TESTBOY TV 700 Bedienungsanleitung

Operation

On / off switch

To switch the instrument On / Off, press the button 5.
After switching on, locating metal is automatically activated.
The TV 700 automatically switches off after approx. 5 minutes, in order to save the battery capacity.

Backlighting

The display backlighting is permanent.

Replacing the battery

To replace the battery, open the battery compartment (12). When inserting the new battery, ensure that the polarity
is correct. Close the battery compartment.
Replace the battery when the battery symbol is displayed without segments on the display, or the instrument
switches off immediately after switching on.
Batteries must not be disposed of with normal domestic waste. There will be a collection point
near you!
Remove the batteries if the instrument is not in use for a long period of time, in order to
protect the instrument from damage.

Calibration

Hold the TV 700 in the air remote from all objects that could be detected. The instrument is activated by briefly
pressing the On/Off button. Do not wear a ring on the hand carrying the instrument and remove wristwatches,
because metallic objects can influence the search result.
Before using each time, the instrument must be examined for signs of damage or
contamination.
Self-calibration
The self-calibration is carried out directly after switching on the instrument or switching the measuring function.
This is confirmed by an acknowledgement sound and the green LED illuminating. For the maximum sensitivity, it is
recommended to keep the instrument away from metallic and magnetic disruptive variables in the air.
Recalibration
For this, press the button [6] or [7] (when switched on) for 3 seconds, depending on the range selected.
Recalibration is always recommended if the instrument responds oversensitively. This is best carried out at a free
position of the wall, well away from metallic and magnetic disruptive variables.
For limiting, recalibration must be carried out several times in the immediate vicinity to the measurement object by
moving over the area several times.
