While the 400W-series unit is acquiring a position, 

let’s take a minute to dial in the active and standby 
frequencies you’ll be using for the first phase of your 
flight. The 400W-series display is divided into separate 
“windows” (or screen areas), including a COM window, 
VLOC window, and the GPS window.

Pushing the small left knob activates the tuning 

cursor in the desired frequency window. To select the 
active frequency, you must first enter the frequency 
in the standby field, and use the COM flip-flop (or 
VLOC flip-flop) key to move it to the active field. 

1.  If  the  tuning  cursor  is  not  currently  in  the 

desired  window  (COM  or VLOC),  press  the 
small  left  knob  momentarily  to  switch  the 
highlight between the COM and VLOC win-
dows. Adjusting the frequencies with the large 
and small left knobs will affect the standby 
frequency. 

2.  Turn the large left knob to select the desired 

megahertz  (MHz)  value.  For  example,  the 
“135” portion of the frequency “135.325”. 

3.  Turn the small left knob to select the desired 

kilohertz (kHz) value. For example, the “.325” 
portion of the frequency “135.325”. 

4.  To activate the selected frequency, press the 

appropriate flip-flop key—COM for commu-
nication frequencies or VLOC for VOR/Localizer 
frequencies. 

Once you’ve entered the active frequency, simply 

repeat steps 1 through 3, above, to enter the standby 
frequency. After both communication frequencies have 
been entered, you may elect to keep the COM window 
‘hot’ by leaving the cursor on the standby frequency, or 
move the cursor to the VLOC window by pressing the
small left knob. 

Once you’ve entered the active frequency, simply 

repeat steps 1 to 3, above, to enter the standby fre-
quency. After both communication frequencies have 
been entered, you may elect to keep the COM window 
“hot” by leaving the cursor on the standby frequency, 
or move the cursor to the VLOC window by pressing
the small left knob. 

 

NOTE: When selecting VLOC frequencies, the 
tuning cursor automatically returns to the COM 
window after 30 seconds of inactivity. 

 

NOTE:  GPS level of service annunciations (LPV, 
ENR, etc.) are not applicable to the external CDI 
(or HSI) when VLOC is active.
