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. Inserting a USB charging cable or
audio cable into the port will eanhance the signal reception as well.

enter Backlight setting of LCD, press ‘NEXT’ button to select the time of
