3.1 Functional Controls. For ease of use, all controls for
the F3 are located on the Handle. Figure 12 illustrates the location
of all controls:
a. On/Off Switch.
•
The F3 is switched on by sliding the On/Off Switch toward the
Handle. When switched on, the F3 completes a series of
internal start-up
microprocessor and self-tests which check internal power
supplies, transmitter etc.
•
These internal diagnostics take approximately 12 seconds to
complete during which the operator will hear a series of rising
tones (known as the Start-Up Tones).
•
At the completion of the Start-Up Tones the F3 emits a low
steady tone known as the Threshold Tone, which confirms to the
operator that the F3 is functioning correctly.
