Frequently Asked Questions - BTFM1IS iSimple
How do I pair my phone with the iSimple BTFM1IS?
Turn on the transmitter and set your phone to Bluetooth scan. Select iSimple BTFM1IS from the list. If prompted, enter PIN 0000 or 1234. The device will connect automatically next time.
Why is there static noise on the FM radio?
Static often occurs if the FM frequency is not clear. Try a different frequency with no active station. Move the transmitter away from other electronics. Ensure the vehicle antenna is fully extended.
What is the effective transmission range?
The FM signal typically works within 10-30 feet (3-10 meters) of the vehicle. Obstacles can reduce range. For best performance, place the transmitter near the radio antenna.
How do I find the best FM frequency to use?
Scan your car radio for an empty frequency with minimal static. Note it, then set the transmitter to the same frequency using the channel buttons. Avoid frequencies used by strong local stations.
Can I charge my phone while using the transmitter?
Yes, the BTFM1IS includes a USB charging port (5V/2.1A) to charge your phone or other devices while streaming music.
Why is the audio volume very low?
First, increase the volume on your phone. Then adjust the transmitter's volume control. If still low, check your car radio volume and ensure the aux input is not selected if using FM mode.
Does the transmitter support hands-free calling?
Yes, the device has a built-in microphone and button to answer/end calls. When a call comes in, music pauses. Press the call button to accept, and speak normally.
How can I update the firmware?
The iSimple BTFM1IS does not support user firmware updates. It is pre-configured with stable firmware. No update is required.
What devices are compatible?
Any device with Bluetooth 4.0 or higher (smartphones, tablets, laptops) or a 3.5mm aux output can be used. Also works with older phones via the aux cable.
Why does the Bluetooth keep disconnecting?
Interference from other Bluetooth devices or Wi-Fi can cause disconnects. Turn off unused Bluetooth devices and keep your phone close. Also, ensure the car's ignition does not cut power to the transmitter.
