3.4 USB issues
3.4.1
iPod/iPhone not charging or playing
– these devises are not supported through the USB. To play iPod/iPhone,
use the headphone jack and connect to the AUX inputs of the INFPRV-250. Recommended additional purchases
are the SEAMINI or SEAUSBMINI to clean up this connection and make it easier to use.
3.4.2
MP3 player is not charging or playing
– not all mp3 players will play via USB. The difference is in the
software of the mp3 player. Recommended additional purchases are the SEAMIN2 or SEAUSBMINI.
3.4.3
Flash Drive/ Thumb drive not playing
Only MP3 or Windows Media files are supported. These files can be recognized by viewing their file extension
on a computer; i.e., the file “My Favorite Song” will be followed by a “.” and the extension “mp3” or “wma”.
Some computer operating systems have extension view disabled. The feature can usually be enabled in the
computer’s folder properties.
ITunes music files will not play as these are not in mp3 format. Software converters can be purchased to
convert these files as others to mp3 format. Do not exceed a bit rate of 128 Kbps when converting.
Only drives formatted to FAT or FAT2 are supported. Most flash drives come this way standard.
Some flash drives com preloaded with proprietary software or other media organizational software that will
prevent the INFPRV-250 from reading the contents. Best practice is to completely format the drive to erase all
contents before loading music files.
Supported formats must not exceed a bit rate of 128 Kbps.
Check USB outlet for corrosion or rust. Initiate a warranty claim if rust is found and you are under warranty.
3.5
Poor or no Reception
3.5.1
For an amplified antenna
Ensure the antenna is connected to power and ground according to manufacturer’s instructions
The antenna wire should never be coiled or wound up.
Check proximity of radio, speakers and antenna to gages, GPS equipment, depth finders, LED lighting or any
other source of Radio Frequency Interference (RFI) and Electronic Magnetic Interference (EMI).
3.5.2
For all other antennas
Inspect the antenna for torn wires.
The antenna wire should never be coiled or wound up.
Check proximity of radio, speakers and antenna to gages, GPS equipment, depth finders, LED lighting or any
other source of Radio Frequency Interference (RFI) and Electronic Magnetic Interference (EMI).
3.5.3
LED lighting causes low FM/AM audio or poor reception
•
Never bundle the power source wires of the LED lighting to the power wires of the radio.
•
If needed, the LED power wires and radio power wires should intersect at a 90 degree angle.
•
The radio’s antenna must be as far away from the LED lights and power source as possible.
•
The radio’s speakers also must be as far away from the LED lights as possible
•
If all fails, upgrade the LED lights to a brand that is guaranteed not to emit RF or EMI.
