Spectrum Display
1. By pressing the EQ/LEVEL switch once when the EQ mode
is engaged, the display will change into a spectrum display.
By checking the spectrum display readings, you may at a
glance confirm the level of each of the 7 frequency bands,
and make any necessary adjustments as you see fit.
2. Two sensitivity levels of the spectrum display are available:
Hl and LOW.
For proper readings, press the HI/LOW switch and set the
mode to LOW listening at high volumes, and set it to HI
when listening at LOW values.
The LOW position is also convenient if you find the level
readings
irritating
during
driving.
