connected, press and hold the control button for 2 seconds. The LED should
start flashing Red and Green on the back of ISFM2351 module once in
discoverable mode.

Please note: The ISFM2351 remembers the last 8 phones that were paired with it
and sorts them in priority from most frequently used to least. When a 9th phone is
paired, the least used phone will be bumped / removed.

additional settings and features. Download the App for free for your iPhone from the
iTunes App Store, or for your Android smartphone using Google Play.

to play back your streaming audio and phone calls through your vehicle. Additionally
the App allows you to clear the list of paired devices from memory. This is useful at
the point of installation.

5. User Operation

The ISFM2351 will automatically reconnect with your paired phone when entering the
vehicle. This ensures that your hands-free calls will be routed through the FM radio, or
Aux input in your vehicle.
