QUICK REFERENCE
GUIDE
1. Turning the device on and off. To turn the device on or off, press and hold the buon. Immediately aer turning on,
the device will sound (in morse code) the baery voltage level. When the device is on, the top LED indicator is acve and
indicates the current baery power level. Each LED is assigned a level value (%). When it lights up the energy level is at
least as the value in the descripon, when it blinks it is 10% less of that value.
2. Connecng the power supply - charging the baery. The device can be powered by a photovoltaic panel or other DC
power source. We recommend using photovoltaic panels with a nominal power of 20 was or more. While the power
source is connected, the built-in baery is charged, and the LED indicator shows the level of current that is currently
being directed to the baery. When the baery is >90% charged, and no load is connected to the power output, the
charging current indicaon will decrease unl all LEDs turn off when charging is complete. The device has an MPPT
funcon, which maximizes the obtaining of energy from the photovoltaic panel, MPPT performs a full scan of the
photovoltaic panel every few minutes. During this me, for about 1 second, the lower LED indicator will turn off and
then return to the current display.
3. Usage. Connect the transceiver to the power output, keep the correct polarity. The diameter of the power wires
should be appropriate for the current drawn. Do not use wires with a diameter of less than 1 mm2. While the
photovoltaic panel is connected to the power input, and the transceiver is connected to the power output, the energy
from the photovoltaic panel will be directed to charge the built-in baery, the rest to the power output. The device has
overload and short circuit protecon at the power output. When an overload or short circuit occurs, the device will shut
down. The device will be ready to turn on again aer a period of 5 seconds.
When it is on, press the buon quickly 2 mes, the morse code will be generated again.
The first full discharge or charge of the baery calibrates the internal energy meter.
