SECTION 7 - DESCRIPTION AND OPERATION (continued)
Legend - Figure 1 (continued)
6. Timer Mode Annunciation - Either the elapsed time (ET) or flight time
(FLT) mode is annunciated here.
7. Frequency Selector Knobs - Selects the standby frequency when FRO is
displayed and directly selects the active frequency whenever either of the
timer functions is selected. The frequency selector knobs may be rotated
either clockwise or counterclockwise. The small knob is pulled out to tune
the 1's. The small knob is pushed in to tune the 10's. The outer knob tunes
the 100's with rollover into the 1000's. These knobs are also used to set the
desired time when the elapsed timer is used in the countdown mode.
8. Off/Volume Control (OFF/VOL) - Controls primary power and audio
output level. Clockwise rotation from OFF position applies primary power
to receiver; further clockwise rotation increases audio level. Audio muting
causes the audio output to be muted unless the receiver is locked on a valid
station.
9. Set/Reset Button (SET/RST) - The set/reset button, when pressed, resets
the elapsed timer whether it is being displayed or not.
10. Flight Time/Elapsed Time Mode Selector Button (FLT/ET) - The Flight
Timer/Elapsed Time mode selector button, when pressed, alternatively
selects either Flight Timer mode or Elapsed Timer mode.
11. Frequency Transfer Button (FRQ) - The FRQ transfer button, when
pressed, exchanges the active and standby frequencies. The new
frequency becomes active and the former active frequency goes into
standby.
12. BFO Button - The BFO button selects the BFO mode when in the
depressed position (see Note under item 3).
13. ADF Button - The ADF button selects either the ANT mode or the ADF
mode. The ANT mode is selected with the ADF button in the out position.
The ADF mode is selected with the ADF button in the depressed position.
14. Index (Rotatable Card) - Indicates relative, magnetic, or true heading of
aircraft, as selected by the HDG control.
