3.3 പവർ കണക്ഷൻ
Connect the DC power cord with the fuse to your vehicle's 12-volt power source. Ensure proper polarity (red to positive, black to negative) to prevent damage to the unit. The fuse provides protection against power surges.
3.4 ആന്റിന കണക്ഷൻ
Connect your external CB antenna (sold separately) to the antenna port on the main radio unit. For optimal performance, ensure your antenna is properly tuned and grounded. An improperly tuned antenna can lead to poor transmission/reception and potential damage to the radio.
4. അടിസ്ഥാന പ്രവർത്തനം
4.1 പവർ ഓൺ/ഓഫ്
Press and hold the Power button on the microphone to turn the unit on or off. The LCD display will illuminate upon power-up.
4.2 വോളിയം നിയന്ത്രണം
Use the Volume Up/Down buttons on the microphone to adjust the audio output level. An external speaker (such as Uniden's BC15) is recommended for very noisy environments.
4.3 Squelch Control (SQ/ASQ)
The Squelch control eliminates background noise when no signal is being received. Adjust the SQ/ASQ level to a point where background noise is suppressed, but weak signals can still be heard.
4.4 ചാനൽ തിരഞ്ഞെടുക്കൽ
Use the Channel Up/Down buttons on the microphone to navigate through the 40 available CB channels. The selected channel number will be displayed on the LCD.
4.5 NOAA കാലാവസ്ഥാ മുന്നറിയിപ്പുകൾ

5. വിപുലമായ സവിശേഷതകൾ
5.1 7-Color Backlit LCD Display
The microphone features a large 1 3/8" x 3/4" LCD display with 7 selectable backlight colors. This allows users to customize the display to match their vehicle's interior lighting or personal preference for optimal readability.
5.2 Noise Reduction Circuit (NRC)
The CMX760 incorporates a Noise Reduction Circuit (NRC) to minimize background noise during both transmission (Tx) and reception (Rx). This feature is particularly beneficial in noisy vehicle environments, enhancing communication clarity.
5.3 സ്കാൻ ഫംഗ്ഷൻ
Activate the scan function to automatically sweep through active channels. This allows you to monitor multiple channels without manually changing them. The scan can be configured for either squelch scan or time scan.
5.4 VOX (വോയ്സ് ഓപ്പറേറ്റഡ് എക്സ്ചേഞ്ച്)
The VOX feature allows for hands-free transmission by detecting your voice. You can adjust the VOX sensitivity level (VLE) and the VOX delay time (VTI) to suit your speaking habits and environment.
5.5 RF ഗെയിൻ കൺട്രോൾ
The RF Gain control adjusts the sensitivity of the receiver. In areas with strong signals, reducing the RF Gain can help prevent overloading the receiver and improve clarity. In areas with weak signals, increasing the RF Gain can help pick up distant transmissions.
5.6 Roger Beep
The Roger Beep feature transmits a short tone at the end of your transmission, signaling to other users that you have finished speaking. This can be enabled or disabled via the menu settings.
5.7 High Cut Filter
The High Cut filter reduces high-frequency noise components in the received audio, making voices clearer and less fatiguing to listen to over extended periods.
5.8 Microphone Gain Control
Adjust the microphone gain (MG) to control the sensitivity of your microphone. This helps ensure your transmitted audio is clear and at an appropriate level for other users.

- ആൻ്റിന ട്യൂണിംഗ്: Regularly check your antenna's Standing Wave Ratio (SWR) to ensure optimal performance and prevent damage to the radio's transmitter. Consult your antenna's manual for tuning instructions.
- ഫ്യൂസ് മാറ്റിസ്ഥാപിക്കൽ: If the radio does not power on, check the fuse in the DC power cord. Replace it with a fuse of the same type and rating if blown.
8. പ്രശ്നപരിഹാരം
- ശക്തിയില്ല: Ensure the DC power cord is securely connected and the fuse is intact. Check your vehicle's 12V power source.
- മോശം സ്വീകരണം/പ്രസരണ സംവിധാനം: Verify your antenna is properly connected, tuned, and grounded. Check the RF Gain setting. Ensure the microphone extension cable is not causing interference; some users report improved performance without it or with a shielded cable.
- വികലമായ ഓഡിയോ: Adjust the Volume and Squelch controls. Check the High Cut filter setting. If using an external speaker, ensure it is properly connected.
- Microphone Issues (e.g., weak transmit, stuck in transmit): This can sometimes be related to the microphone extension cable or grounding issues. Try connecting the microphone directly to the unit if possible to diagnose. Ensure proper grounding of the radio unit.
