6. Instruccions de funcionament

6.1. Basic Frequency Measurement

1. Ensure the device is powered on and the antenna is attached.
2. Place the frequency counter near the two-way radio or signal source you wish to measure. For best results, position the counter's antenna close to the radio's antenna.
3. Activate the transmission on the two-way radio (e.g., press the PTT button).
4. The frequency counter will automatically detect and display the frequency of the transmitted signal. The display will show the frequency in MHz, along with a signal strength indicator.
5. To stop the measurement and hold the current reading, press the F2 (Stop) button. Press F2 again to resume continuous measurement.

6.2. CTCSS/DCS Measurement

The SF-103 / A-SF103 is capable of measuring CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digital Coded Squelch) codes, which are used to filter out unwanted transmissions on a radio channel.

Figure 6.1: The SF-103 / A-SF103 displaying its CTCSS/DCS measurement capability, allowing for testing of standard and non-standard codes.

1. While measuring a frequency, if the signal contains a CTCSS or DCS tone, the counter will automatically detect and display it.
2. The detected CTCSS tone will be shown as a frequency (e.g., 88.5 Hz), and DCS will be shown as a three-digit code (e.g., D023N).

6.3. Navegació del menú

Utilitza el F3 (Menu/Down) i F4 (About/Up) buttons to navigate through the device's menu options. The menu allows for adjustments such as gate time, display settings, and other advanced features. Refer to the on-screen prompts for specific menu functions.

6.4. Operational Demonstration Video

7. Manteniment

• Neteja: Feu servir un drap suau i sec per netejar el dispositiu. No utilitzeu productes de neteja abrasius ni dissolvents.
• Emmagatzematge: Guardeu el dispositiu en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes quan no l'utilitzeu.
• Cura de la bateria: Per allargar la durada de la bateria, eviteu descarregar-la completament amb freqüència. Si la guardeu durant un període prolongat, carregueu-la fins a un 50% aproximadament i torneu-la a carregar cada pocs mesos.
• Cura de l'antena: Handle the antenna carefully. Do not bend or force it, as this can damage the connector.

8. Solució De Problemes

• El dispositiu no s'encén: Assegureu-vos que la bateria estigui carregada. Connecteu el carregador i torneu-ho a provar. Si el problema persisteix, contacteu amb el servei d'assistència.
• No frequency reading:
  • Ensure the two-way radio is transmitting.
  • Check that the antenna is securely attached to the frequency counter.
  • Move the frequency counter closer to the transmitting radio.
  • Verify the signal strength of the transmitting radio is sufficient.
• Incorrect frequency reading:
  • Ensure there are no other strong interfering signals nearby.
  • Check the frequency range setting in the device's menu (if applicable).
  • Ensure the radio is transmitting on the expected frequency.
• La pantalla és tènue o parpelleja: Pot ser que la bateria estigui baixa. Torneu a carregar el dispositiu.
