1 When connecting the device to a charger with an output current of at least 3A.
2 If your PC is limited to the maximum current supplied to the USB port, the instrument will automatically limit the
maximum charging current according to the current USB specification.
3 At an ambient temperature of plus 20 ± 5 ° C after a full charge of the battery. The display is on, the volume of the built-
in speaker is at a medium level.
5. Turning on the receiver
Do not connect the RF input jack while the charger is connected or USB connected to a PC. If these recommendations
are not followed, the radio receiver may fail.
The use of the receiver in the open air during snowfall or rain is prohibited. If the receiver is brought in during the
cold season from a cold room or from the street to a warm room, do not turn it on for a sufficient time for the condensate
to evaporate from the receiver.
5.1. Make sure that the radio receiver has no external damage and the battery is charged. Charge the discharged battery.
When the charger is connected, the maximum charging current is automatically determined. To reduce the battery charging
time, it is recommended to use industrial power supplies (chargers) with a maximum output current of 3 A as a charger. When
charging is complete, the CHARGE indicator will turn off.
It is allowed to operate the device while charging the battery, provided that the power source is capable of providing an
output current of at least 1500 mA. If the charger or the USB port of the PC is not able to provide the current required for the
operation of the device and charging the battery, the device will automatically lower the current consumption until the battery
is completely stopped charging.
5.2. Press and hold button (2) for 2 seconds. The receiver turns on. Tune the receiver to the frequency of interest, select
the required type of demodulator, adjust the required graphs. User settings will be saved in the device's memory and will be
automatically installed on subsequent power-ups.
During operation, the receiver display may generate pulse interference at some frequencies. To listen to the
broadcast without interference, it is recommended to turn off the display by double pressing the multifunctional button (2).
5.3. To turn off the device, press and hold the button (2) for 2 seconds. The device screen will go off, the device will turn
off. Each time the device is turned off, the main user settings are recorded in non-volatile memory, which allows you to avoid
configuring the device at the next turn-on.
6. Device screen
6.1. The instrument displays graphs of the spectrum /
waterfall of the bands of interest. The current settings and
interactive buttons for controlling the instrument interface
are located at the bottom of the screen.
6.2. The main components of the screen:
(1) - graphs area;
(2) - the button for controlling the display of graphs. When
moving with pressing and holding, the ratio of the sizes of the
graphs on the screen changes. Pressing and holding without
moving opens a menu for selecting the types of graphs and
diagrams to display;
(3) - volume control button for audio devices;
(4) - S- meter;
(5) - the pull-out area of the device menu
(6) - tuning frequency selector with buttons for discrete
adjustment by selected digits;
(7) - information about the type of the current demodulator and demodulation bandwidth;
(8) – built-in battery status indicator.
6.3. Built-in battery status indicator:
lightning indicator-the battery is charging;
the battery indicator is completely filled with white color – the battery is fully charged;
indicator in the form of a white contour of the battery – the battery is low, it is necessary to charge it;
the device displays a message about a critical charge level – the battery is completely discharged, the device will
automatically turn off.
The red vertical line on the graphs indicates the current frequency of the receiver setting. The gray background around the
setting pointer reflects the selected demodulation band. As the demodulation band changes, the width of the gray area will
change.
The ARINST SDR Dreamkit V1D radio receiver has the ability to supply an internal voltage of 12V to the RF input. The
implementation of this function allows you to supply power to external preselectors, antenna amplifiers, low-noise amplifiers(
LCS), emitter repeaters, etc. active devices. The maximum current consumption for external devices should not exceed the
value specified in Table 4. Power on for external devices is carried out in the main menu of the receiver on the «Device» tab.
In case of exceeding the maximum permissible current for powering external devices, specified in Table 4, the voltage from the
RF connector will be removed, and the user will see a warning on the maximum current exceeding «DC overload detected!»
оn the screen. For further use of the power supply of the external device from the radio receiver, it is necessary to reduce the
current consumed by the external device, or connect a device, the maximum current for which does not exceed the value
indicated in Table 4. After that, turn on the power at the RF input using the switch in the menu.
It is strictly forbidden to connect a short-circuited load to the input of the receiver and supply an internal voltage to
the RF connector. It is also not allowed to connect a short-circuited load to the input if the voltage is already applied to the
RF connector. This will damage the radio receiver !!!
