I am trying to help someone out who is currently cruising and can not
contact Furuno. THey are trying to use their FS1503 on lower sideband
but there is some 'unclipping' procedure required to enable lower
sideband. Does anyone have the details on this procedure? They seem to
think its a keying sequence on the controls. I'm pretty sure there is
a jumper which needs to be clipped.

Any help would be great.


Patrick, I hope you are still reading this thread as I can't seem to
find a valid email address for you.

Here is the procedure to unlock the LSB function in the Furuno FS1503:



You need to change system parameter 9914 to "0" to enable LSB capability.


SYSTEM PROGRAMMING PROCEDU


1) While pressing and holding down the [CH] key, turn the power on to
enter system programming mode, release the [CH] key after unit is on and
"MEMO" shows in the display.




2) Select function 9999 by rotating the FREQ/CH knob.




3) Press [CH], [1], [5], [0], [3], and [ENT] keys. ("1503" is password.)




4) Select function 9914 by rotating the FREQ/CH knob, then press [CH],
[0], and [ENT] keys.




5) To finish up, escape the programming mode by simply turning off the
radio.




The system programming is completed.
