I've had one of these radios for quite awhile but have one minor problem
w/ it. One of the pilot lamps for the display appears to have burned
out. This is the one on the left -- the one that stays on dim when the
radio is off while connected to the wall wart. The screws to get the
back cover off are odd -- look like a star (which I don't have a
screwdriver for). What type are they? Also, does anyone know
right-off-hand what type of replacement bulb is required?
