GAMMA-SCOUT
®
is powered by a Lithium Thionyl Chloride cell of 2.7 - 3.7 voltage. The device will
continue functioning until the cell voltage is down to 2.8. When the voltage drops below this value,
the battery symbol will appear in the display. The data will be retained, even at total breakdown of
voltage. The model RECHARGEABLE has a rechargeable power supply (via USB or power supply
unit that is included in delivery)
Indicating the Battery Voltage
Press the button to indicate the existing battery voltage. The display will show the cell voltage
available when the electronic system is under maximum load.
Battery change
The battery is soldered on the circuit board to prevent any data loss. Due to our extremely low
currents (of approximately 10 microampere), plug-in batteries would constantly lead to current
interruptions because the mating surface would oxidize). In case the user wants to integrate a new
battery, the basic parameters can be restored by pressing the reset button after having changed the
battery.

opening of the case beside the USB interface on the circuitboard. Any reset will set the clock back
to factory standards.
Attention:
The reset may delete your filed data.
Ticker (not available in the basic model)
A double click of the button will display the word “on” – which means that the ticker can be
switched on now. Pressing the button will switch on the ticker and the symbol “speaker” is dis-
played. In case the ticker is already on, pressing the button switches it off. The double click will
display the word “off” and the “speaker” symbol will disappear.

power than the monitoring operation at environmental impact. Therefore, the ticker is switched off
internally after 10 minutes of use. If the ticker is used once per day, the power consumption is still
within the limits of a long-lasting battery. If the ticker is used more often, the battery will last for a
shorter period. In this case, a maintenance fee will be charged for a battery change. Number and
duration of ticker use is locked internally.
