QUICK REFERENCE
GUIDE
1. Turning the device on and off.
To turn the device on or off, press and hold the bu on. Immediately a er turning on,
the device will sound (in morse code) the ba ery voltage level. When the device is on, the top LED indicator is ac ve and
indicates the current ba ery power level. Each LED is assigned a level value (%). When it lights up the energy level is at
least as the value in the descrip on, when it blinks it is 10% less of that value.
2. Connec ng the power supply - charging the ba ery.
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 wa s or more. While the power
source is connected, the built-in ba ery is charged, and the LED indicator shows the level of current that is currently
being directed to the ba ery. When the ba ery is >90% charged, and no load is connected to the power output, the
charging current indica on will decrease un l all LEDs turn off when charging is complete. The device has an MPPT
func on, 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 ba ery, the rest to the power output. The device has
overload and short circuit protec on 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 a er a period of 5 seconds.
When it is on, press the bu on quickly 2 mes, the morse code will be generated again.
The first full discharge or charge of the ba ery calibrates the internal energy meter.
