Tone
Figure 4.15
Adjusts the tone of the threshold. The user may set this to the preferred
tone, e.g. the tone at which the operator’s hearing is most sensitive.
At minimum position, threshold is set at a low tone. Turning clockwise
increases the tone to higher pitch.
Signal Pitch
Figure 4.12
Adjusts the pitch response of the target signal.
In Figures 4.13 and 4.14 the curving line represents the high/low pitch
response to a target. The dotted line represents the threshold tone.
• At minimum position the high/low pitch variance to a target is
reduced.
• At maximum position the high/low pitch variance to a target is
increased.
