introduction

The FieldSENSE 2.0 is the next generation in Personal RF Moni- tors specifically designed for

protecting personnel working near broadcast and telecommunications transmitting antennas from

EMF/RF overexposure.

The FieldSENSE 2.0 measures both E and H fields spanning from 50 MHz to 6 GHz with an

isotropic probe architecture. The probe response is shaped to internationally accepted exposure

safety limits and is designed for both body worn, handheld or remote monitoring applications.

Make sure that the device is within its 2-year calibration cycle and do not use it if it appears to have

been damaged.

Used correctly, it will give an indication of field levels approaching or exceeding associated exposure

limits and is a valuable tool to assist in preventing EMF/RF overexposure.

** NOTE: This device is only to be used by RF trained personnel with a complete understanding of

the risks involved with working with RF and know the necessary precautions to be taken.

Furthermore, only use this device within the limits of the design specifications and ensure that it is

not damaged prior to usage.

•Prior to entering an area where transmitting antennas could be present be sure to switch your

FieldSENSE on.

•Switch the FieldSENSE on by pressing and holding the On/Off button for approximately 1

second.

•The LEDs illuminate in sequence followed by a BEEP. Once on the power indicator will flash.

•Should the battery level below the low battery indicator will illuminate. Replace the batteries

•When the exposure level rises above 50% an audible alarm is sounded.

•When close to or exceeding 100% of the exposure limit, the necessary precautions need to be

taken.

•Once switched on the field strength data logger will record all field values measured. These are

accessible via the PC application available from www.FieldSENSE.com. A micro B male USB

connection will be required.

•Once the FieldSENSE is on, the fall detect & alarm system is armed and in the event of a fall

being detected an alarm will sound which can only be cleared by switching the device off and on

again.

•To ensure that the device is not inadvertently left switched on causing unnecessary drain on the

batteries a timer will switch the unit off after 8 hours.

* Always adhere to the relevant safety regulations pertaining to RF exposure in the country of use.

•Once the FieldSENSE is switched on the cumulative exposure from all sources present are stored

as Maximum, E and H percentages together with the associated date and time.

•The values are a percentage of the associated exposure guideline power density, either

referenced to E or H field.

•The FieldSENSE 2.0 can also capture voice notes which are paired with the measured data.

•Once the device is on, double tap the power button and the Audio re- cording LED will illuminate.

•Speak directly into the front of the device slowly and clearly for best performance.

•A single press of the button will end the audio recording.

•Voice notes can be downloaded from the FieldSENSE using the program available from

www.fieldsense.com

Fall detection & alarm

•The FieldSENSE 2.0 is equipped with a 3-axis accelerometer which is able to detect if the device

experiences a fall.

•This is immediately active when the device is switched on, and should the device detect a fall of

approximately 2m it will sound an alarm

•The alarm can only be cleared by switching the device off again.

•The goal of this is to immediately draw attention to a climber who may have fallen and may be

unconscious.

•The alarm, if uncleared, will continue until the batteries are exhausted.

Replacing the batteries

•When the Low Battery Indicator begins to flash, replace the batteries.

•Open the elastomer flap at the bottom of the FieldSENSE revealing the battery lid screws.

•Remove the screws and lid and slide out the old batteries. Dispose of these correctly.

•Insert 2 x new AAA (LR03) batteries.

•Replace the battery lid and retighten the screws.

•Securely close the elastomer cover to ensure the moisture seal remains intact.

*Removing the batteries for an extended period of time will

cause the device to lose time on the internal clock. This is

corrected by plugging it into the USB connection on a PC.

1. The response is a combined E & H field deviation from the relevant standard including the isotropy

as is reported by the LED indicators.

2. Positive values indicate conservative readings i.e. early warning.

3. NB! Only use the device in this frequency range, measurements outside of this frequency range will

not be accurate and cannot be guaranteed

4. H field contributions assessed from 50MHz —1 GHz only.

5. Not suitable for Radar applications.
