Introduction
This guide describes the operation of the Apollo SL40
VHF Communication Transceiver.
Display The 1-line by 16-character display is composed of 5x7
dot matrix alphanumeric high intensity LEDs. A
photocell is located in the top left corner of the front
panel display. The photocell automatically controls the
intensity of the display from low brightness at night to
high brightness during daylight operation. Brightness
levels may also be controlled manually.
Annunciators Several annunciators are used to help indicate the
operating modes of your Apollo SL40. The TX
(Transmit) annunciator is lighted whenever you are
transmitting. If the avionics bus drops below 9 VDC, the
SL40 will not transmit. An LED will be lighted above
the MON and RCL buttons when these functions are
selected. An “s” will appear to the left of the Standby
frequency. An “m” will appear to the left of the Standby
frequency when you are using the Monitor function. An
“I” indicates the Intercom function is being used.

Controls Power/Volume/Squelch
The knob on the left side of the SL40 controls power
on/off, volume, and squelch test. Rotate the knob
clockwise (CW) past the detent to turn the power on.
Continuing to rotate the knob to the right increases
speaker and headphone amplifier volume level. Rotate
the knob to the left to reduce the volume level. Pull the
knob out to disable automatic squelch. The SL40 may be
installed to have the on/off switch disabled and to have
power controlled from the avionics panel.
Large and Small Knobs
The dual concentric knobs on the right side of the SL40
are used to select frequencies or to view the features
available within a function. Details are provided in the
appropriate section.
Buttons Five backlighted buttons allow you to access the
functions in your Apollo SL40.
Flip/Flop (Arrows)
Press the Flip/Flop button to switch between the active
(left-most) and standby (right-most) frequency.
Switching between frequencies is disabled while you are
transmitting.
EC (Emergency Channel)
Press the EC button to load the Emergency Channel
(121.500 MHz) as the standby frequency. The Monitor
function is automatically enabled.
MON (Monitor)
Press the MON button to listen to the standby frequency.
When the active frequency receives a signal, the unit
will switch automatically to the active frequency.
RCL (Recall)
Press the RCL button to retrieve stored frequencies.
MEM (Memory)
Press the MEM button to store the displayed Standby
frequency in memory.

Basic Operation
This section introduces the basic operating details of the
Apollo SL40 VHF Communications Transceiver.
Power
On/Off Turn the Power/Volume control clockwise past the OFF
detent. The SL40 may be installed to be powered from
the avionics panel so the on/off control will be disabled.
Volume Turn the Power/Volume control clockwise to increase
the volume level and counterclockwise to decrease
volume.
Selecting
Frequencies New frequencies are first selected as a Standby
frequency and then toggled to the Active side when
desired. While viewing the frequency display, use the
Large and Small knobs on the right side of the SL40 to
select the desired frequency.
1. Turn the Large, outer knob to change
the values in 1 MHz increments. The
MHz selection range is between 118 and
136 in 1 MHz steps.
2. Turn the Small, inner knob to change
the values in 25 kHz increments. The
kHz selection range is between 000 and
975 kHz in 25 kHz steps. Note that only
two digits are displayed to the right of
the decimal point.
Turn the Largeand Small knobs clockwise to increase
and counterclockwise to decrease the frequency values.
Standby frequency selection is not inhibited during
transmit.
Press the Flip/Flop button to toggle the
Standby frequency to the Active
frequency.

Frequency
Monitoring The Frequency Monitoring function allows you to listen
to the Standby frequency, while monitoring the Active
frequency for activity.
Press the MONbutton to listen to the
standby frequency. A small “m” is
displayed in front of the Standby
frequency. When the Active frequency
receives a signal, the unit will switch
automatically to the Active frequency
and then switch back when activity
ceases. An arrow (<or >) will point to
the frequency that you are currently
listening to. A slight clicking sound
occurs when the radio is checking the
Active frequency for activity. The
Monitor function is deactivated when
you press MON.
Recalling a
Frequency The SL40 can access several areas of stored frequencies.
The SL40 can also receive airport frequencies if
connected to certain Apollo GPS receivers.
Remote (REM)
The Remote function will allow the SL40 to access the
airport frequency database in an Apollo GPS receiver.
Press RCL to view the Remote (REM)
frequencies. Then, turn the Small, inner
knob to display the available
frequencies. The waypoint type and
frequency are displayed.
If not connected to an Apollo GPS, or
the list is not received, the list will not
be available.
