4. સેટઅપ
4.1 બેટરી ઇન્સ્ટોલેશન
- ખાતરી કરો કે ટ્રાન્સસીવર બંધ છે.
- યુનિટની પાછળ બેટરી કમ્પાર્ટમેન્ટ કવર શોધો.
- Slide or unlatch the cover to open the compartment.
- Insert one AAA battery (sold separately) according to the polarity indicators (+/-) inside the compartment.
- બેટરી કમ્પાર્ટમેન્ટ કવરને સુરક્ષિત રીતે બંધ કરો જ્યાં સુધી તે જગ્યાએ ક્લિક ન થાય.
૫.૨ એન્ટેના જોડાણ
The IC-4300 features an integrated antenna. No external antenna attachment is required.
5. ઓપરેટિંગ સૂચનાઓ
૬.૧ પાવર ચાલુ/બંધ અને વોલ્યુમ ગોઠવણ
- 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 ચેનલ પસંદગી
- 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 પ્રસારણ અને પ્રાપ્ત કરવું
- ટ્રાન્સમિટ કરવા માટે: Press and hold the PTT button. Speak clearly into the microphone (located near the speaker grille). Release the PTT button when finished speaking.
- પ્રાપ્ત કરવા માટે: Ensure the PTT button is not pressed. The transceiver will automatically receive signals on the selected channel.
5.4 મોનિટર કાર્ય
- 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. જાળવણી
6.1 સફાઈ
- Wipe the transceiver with a soft, dry cloth.
