To change station on your Monster Bluetooth FM transmitter, you need to tune the transmitter to an unused FM frequency and then match your car radio to that same frequency. This process eliminates static and interference, allowing you to stream audio from your phone through your car's speakers clearly.
Before you change station on your Monster Bluetooth FM transmitter: A quick checklist
Before adjusting the frequency, complete this setup to ensure the transmitter has power and you know which frequency to use. First, plug the transmitter into your car's 12V cigarette lighter socket. Then, turn on your car so the transmitter receives power. Finally, turn on your car's FM radio and scan for an empty FM frequency between 88.1 and 107.9 MHz, a channel that produces only static, with no music or talk radio. This empty channel is where you will set the transmitter to avoid interference from strong local stations. The FM transmitter typically operates within a frequency range of 88.1-107.9 MHz. The Monster Bluetooth FM Transmitter also has a USB port, allowing you to charge your device while using it.
Method 1: Using the multifunction knob to change the frequency
This method applies to Monster FM transmitter models that use a single multifunction knob for volume and frequency control. Follow these steps:
- Press and hold the multifunction knob button until the frequency display on the transmitter starts blinking.
- Rotate the multifunction knob dial left or right to adjust the transmitting frequency to match the empty frequency you found on your car radio.
- Press the multifunction knob button once to confirm the setting. The display will stop blinking, and the frequency is now locked.
Method 2: Using the CH button to change the frequency
Some Monster FM transmitter models have a dedicated "CH" or "FM Adjust" button for changing frequencies. If your model has this button, use this method:
- Press the CH (FM Adjust) button to enter frequency adjustment mode. The LED display will begin flashing to indicate you can change the frequency.
- Use the left (<) or right (>) buttons to adjust the frequency up or down until it matches the empty frequency you selected on your car radio. For some models (e.g., MHF9-1009-BLK), press the (<) or (>) buttons until the transmitting frequency matches the frequency selected on your car audio.
- Press the CH button again, or wait a few seconds for the frequency to stop flashing automatically, to confirm the new setting.
Finalizing the connection
After setting the transmitter to your chosen frequency, tune your car's FM radio to the exact same frequency you just set on the transmitter. For the best audio experience, it is important to select only one audio source, either your phone's Bluetooth or a wired auxiliary connection, to avoid audio conflicts or distortion. It is important to select only one audio source to ensure a better experience with the product.
Troubleshooting tips for clear sound
If you hear static or interference after changing the station, the most common cause is that the frequency you selected is already in use by a strong local radio station. Try a different empty frequency that has only static. Also, ensure the transmitter is positioned correctly in your car, place it away from metal objects and other electronics that can block the signal. If you encounter any issues with the connection or audio quality, try moving the Monster Bluetooth FM Transmitter to a different location in your car. For more detailed advice, see the guide on the best radio frequency for FM transmitters. These devices, commonly known as FM transmitters for cars, work best when you avoid frequencies occupied by powerful broadcasters in your area.
Frequently Asked Questions
What do I do if the frequency display doesn't start blinking when I press the button?
Make sure the transmitter is plugged in securely and your car is running. If the display still doesn't blink, try pressing and holding the button for a longer duration, up to 3-5 seconds, as some models require a longer press to enter adjustment mode.
Can I use a frequency below 88.1 or above 107.9 MHz?
No. The Monster Bluetooth FM transmitter operates only within the standard FM broadcast range of 88.1 to 107.9 MHz. Frequencies outside this range will not work with the transmitter or your car radio.
Why does my audio cut out or sound distorted after I change the station?
This usually means the new frequency is too close to a strong local radio station. Also, ensure your phone is the only audio source connected to the transmitter.
How do I know which frequency is truly empty in my area?
Scan your car radio manually through the entire FM band. An empty frequency will produce only static or white noise with no hint of music or voices. Avoid frequencies where you hear any broadcast, even faintly.
Will changing the station on the transmitter affect my Bluetooth connection?
No. Changing the FM frequency only affects the radio signal sent to your car stereo. Your Bluetooth connection between the phone and transmitter remains active and independent of the FM setting.
