Troubleshooting
What can I do to improve poor FM reception?
1. Check for sources of FM interference. The FM antenna installed in the SP850 may be picking up outside
interference. Check to see if the device is within three feet of any other electronic devices such as: televisions,
cable boxes, wireless internet routers, dimmer switches, and fluorescent/energy-saving lights, blinking seasonal
lights, microwaves or similar appliances. If so, move the SP850 away from such devices.
2. Inserting a USB charging cable or audio cable into the port will enhance the signal reception as well.
