Note: When you cross a waypoint the first time when sequencing is suspended, a message
will be generated to remind you to enter the desired inbound course for your hold. This
message will ask you to press ENT to enter your inbound course or any other key to ignore
the message. Pressing ENT when this message is displayed will result in displaying the
course entry page, just as if you had pressed Direct-To button twice.
7.4.4 Basic Communication Functions
a) Comm functions
To select the comm function display on the SL60 press the button labeled Comm. Pressing
Comm again, when in the Comm mode will activate the standby frequency monitor and an
‘M’ will be displayed by the standby frequency. The standby frequency will be monitored
by the audio output, with a slightly reduced volume and audio quality, unless there is activity
on the active frequency.
b) Flip Flop Key
Pressing the flip flop key will transfer the standby frequency to the active frequency and
vice-versa.
c) Standby Frequency Selection
The standby frequency may be selected by using the large and small knobs. The standby
frequency may also be selected from “stacks” of available frequencies for waypoints, last-
used list, user-stored list, weather channels, and the emergency channel (121.50). Refer to
the user’s manual listed in Limitation 1., for details.
d) Optional
The Apollo SL60 may optionally connected to an external frequency flip-flop switch which
duplicates the function of the flip-flop key. It may also provide internal 2-place intercom
capability when installed in aircraft without existing intercom systems. These features are
not used for this installation.
