6. Betjeningsvejledning
6.1 Tænd/sluk
- To power on the device, press the red Power button. The LCD display will illuminate.
- To power off, press the red Power button again.
6.2 Indstilling af frekvens
The frequency range is 0.5MHz to 470MHz. The display shows frequency in 7 digits (e.g., 439.6000MHz will display as 4396000KHz).
- Use the numerical keypad (0-9) to enter the desired frequency.
- Press a function button (e.g., F1) to confirm or set the frequency. (Specific button mapping for frequency setting is not detailed in the provided data, refer to the device's on-screen prompts or included user manual for exact steps).
- Use the Up/Down arrow buttons for fine-tuning the frequency if available.
6.3 Adjusting Signal Strength
The valid signal strength range is -70dBm to -132dBm. Other displayed values for signal strength are invalid.
- Locate the function button related to signal strength adjustment (e.g., F2 or F3).
- Press the corresponding function button and use the Up/Down arrow buttons to adjust the signal strength within the valid range.
6.4 Audio Modulation
The device has a built-in 800Hz audio modulation. Other audio modulation values are invalid.
- Identify the function button for audio modulation (e.g., F4).
- Press the button to activate or deactivate the 800Hz audio modulation.
6.5 Analog/Digital Sub-tone (CTCSS) Function
This feature enhances anti-interference capabilities.
- Consult the device's on-screen menu or the full user manual for specific instructions on activating and configuring analog or digital sub-tone functions.
- Typically, a dedicated function button or menu option will control this feature.
7. Vedligeholdelse
7.1 Rengøring
- Ensure the device is powered off and disconnected from the power supply before cleaning.
- Use a soft, dry cloth to wipe the exterior of the signal generator.

8. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Enheden tænder ikke. | Incorrect or no power supply connected. | Ensure an 8-12V DC power supply is correctly connected and functioning. |
| No RF signal output. | Incorrect frequency or signal strength settings; faulty cable. | Verify frequency and signal strength settings are within valid ranges. Check the RF OUT cable connection. |
| Display shows unusual values for signal strength or audio modulation. | Attempting to set values outside the valid range. | Remember that signal strength -70 to -132dBm and audio modulation 800Hz are the only valid values. Other values displayed are invalid. |
9. Brugertips
- Signal Waveform: The provided information does not specify if the generator produces sine wave or square wave signals. It is typically an RF carrier with AM modulation. For specific waveform details, further testing or manufacturer clarification may be needed.
- Signal Strength Conversion: The signal strength is provided in dBm. If you need to convert this to microvolts (µV), you will need to know the impedance of your system (typically 50 Ohms for RF). The formula for converting dBm to voltage (V) into a 50 Ohm load is V = sqrt(10^((dBm - 10)/10) * 0.05).
- Button Colors: Note that the colors of the buttons may vary and are sent randomly. This does not affect functionality.
