TONE key
Turning the tone function on or off
The TONE status is presented below the TONE key on the display.
If TONE is turned off, TONE
If TONE is turned on, TONE is displayed with a value between -14 and 94 (tone reference value).
The unit of the TONE value is dBµV.
-14 dBµV = minimum level -30 dBµV + 16 dB
94 dBµV = maximum level at ATT ON 110 dBµV - 16 dB
Starting from this value, the level scale is expanded in the range -15 to +15 dB and the level magnitude
is represented by the pitch of a tone (0 dB corresponds to about 400 Hz). The TONE function is a
frequency tone, proportional to the input level.

One can recognize the instantaneous condition by the scaling of the level bar indirectly. See also
