4. सेटअप
4.1 ब्याट्री स्थापना
- ट्रान्सीभर बन्द भएको सुनिश्चित गर्नुहोस्।
- युनिटको पछाडि ब्याट्री डिब्बाको कभर पत्ता लगाउनुहोस्।
- Slide or unlatch the cover to open the compartment.
- Insert one AAA battery (sold separately) according to the polarity indicators (+/-) inside the compartment.
- ब्याट्री डिब्बाको कभर सुरक्षित रूपमा बन्द गर्नुहोस् जबसम्म यो ठाउँमा क्लिक गर्दैन।
४.२ एन्टेना संलग्नक
The IC-4300 features an integrated antenna. No external antenna attachment is required.
5. सञ्चालन निर्देशनहरू
५.१ पावर अन/अफ र भोल्युम समायोजन
- To turn on: Rotate the Power/Volume knob clockwise until a click is heard and the display illuminates.
- To turn off: Rotate the Power/Volume knob counter-clockwise until a click is heard and the display turns off.
- To adjust volume: Rotate the Power/Volume knob while the unit is on. Clockwise increases volume, counter-clockwise decreases it.
5.2 च्यानल चयन
- Use the Up/Down arrow buttons to select your desired communication channel (1-47).
- Ensure all transceivers in your group are set to the same channel for communication.
5.3 प्रसारण र प्राप्त गर्दै
- प्रसारण गर्न: Press and hold the PTT button. Speak clearly into the microphone (located near the speaker grille). Release the PTT button when finished speaking.
- प्राप्त गर्न: Ensure the PTT button is not pressed. The transceiver will automatically receive signals on the selected channel.
5.4 मोनिटर प्रकार्य
- Press the 'Monitor' button to temporarily open the squelch. This allows you to hear very weak signals or background noise on the current channel, which can be useful for checking channel activity.
- Release the 'Monitor' button to return to normal squelch operation.
5.5 Group Mode
- The 'Group' button is used to manage group communication settings. Refer to the full user manual for detailed instructions on setting up and using group codes (CTCSS/DCS tones) for private conversations within a larger group.
6. मर्मतसम्भार
८.१ सरसफाई
- Wipe the transceiver with a soft, dry cloth.
- जिद्दी फोहोरको लागि, हल्का कपडा प्रयोग गर्नुहोस् dampपानी र हल्का डिटर्जेन्टले भिजाउनुहोस्, त्यसपछि सुकाउनुहोस्।
- कठोर रसायन, घोलक, वा घर्षण गर्ने क्लीनरहरू प्रयोग नगर्नुहोस्।
6.2 भण्डारण
- If storing the transceiver for an extended period, remove the AAA battery to prevent leakage.
- चिसो, सुख्खा ठाउँमा भण्डार गर्नुहोस्, प्रत्यक्ष सूर्यको किरण र चरम तापक्रमबाट टाढा।
T. समस्या निवारण
If you experience issues with your IC-4300, refer to the following common problems and solutions:
| समस्या | सम्भावित कारण | समाधान |
|---|---|---|
| शक्ति छैन | ब्याट्री सकिएको वा गलत तरिकाले स्थापना गरिएको। | ब्याट्री बदल्नुहोस् वा ध्रुवता जाँच गर्नुहोस्। |
| प्रसारण वा प्राप्त गर्न सकिँदैन | गलत च्यानल चयन गरियो। दायरा बाहिर। | Verify channel. Move closer to other transceivers. |
| कमजोर अडियो गुणस्तर वा स्थिर | कमजोर सिग्नल। हस्तक्षेप। भोल्युम धेरै कम/उच्च। | Adjust volume. Move to a clearer area. Use Monitor function. |
| Group mode not working | Incorrect group code (CTCSS/DCS) set. | Ensure all transceivers have the same group code. |
If the problem persists after trying these solutions, please contact ICOM customer support or your local dealer for assistance.
