low end, remove the Bottom Lid and flip the tiny black DIP
switch on the lower right edge of the circuit board to the
LEFT (NORMAL) position.
NOTE: REPLACE THE BOTTOM LID after setting the
BOOST switch before using the unit. Some electronic parts
inside are static sensitive and can be damaged from even
a small static charge from a carpet or other soft surfaces.
Always replace the bottom lid after battery replacement or
switch adjustment before the unit is used. To do an A/B
comparison with the bottom removed – play the unit upside
down. DO NOT SET THE UNIT ON A METAL (or any)
SURFACE WITH THE BOTTOM REMOVED!

the “sweetness” they claim to hear from standard Carbon
Zinc type batteries, but you will have to decide what type
best serves your needs.
