3.1 Functional Controls.

For ease of use, all controls for the F3 are located on the Handle.
For information on the additional controls included in the F3L
configuration, refer to Chapter 4. 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 functions including initialisation of the 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.
