• For at slukke: Tryk og hold nede F1 (Power) knappen, indtil displayet slukker.

6. Betjeningsvejledning

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. Menu navigation

Brug F3 (Menu/Down) og 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. Operationel demonstrationsvideo

7. Vedligeholdelse

• Rensning: Brug en blød, tør klud til at rengøre enheden. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
• Opbevaring: Opbevar enheden et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer, når den ikke er i brug.
• Batteripleje: For at forlænge batteriets levetid bør du undgå at aflade batteriet helt ofte. Hvis det opbevares i længere tid, skal du oplade batteriet til ca. 50% og genoplade det et par gange om måneden.
• Antennepleje: Handle the antenna carefully. Do not bend or force it, as this can damage the connector.

8. Fejlfinding

• Enheden tænder ikke: Sørg for, at batteriet er opladet. Tilslut opladeren, og prøv igen. Hvis problemet fortsætter, skal du kontakte support.
• 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.
• Displayet er svagt eller flimrende: Batteriet er muligvis lavt. Genoplad enheden.
