Push the ENT key to accept the data and return to a standard display.   
Alternatively, push the ESC key to abort entry.   
 
Or, push the down arrow key to move to the next item on the configuration menu (LPF). 
 
6-13-2 Configure audio LPF (low pass filter) 
The audio low pass filter is useful to cut off high tones (allowing low tones to pass) to 
improve intelligibility of weak signals in close proximity to adjacent interference and...

The FM transmission in different world areas have been different defaults for de-emphasis. 
  
For example, a value of 759 is selected in Europe, the recovered audio will sound very   
muffled. 
 
The available range is as follows:      THRU, 25uS, 50uS, 75uS, and 750uS 
 
The audio de-emphasis can be set to automode to select the proper setting automatically. 
 
The default is AUTO. 
 
To access the configuration menu, push the FUNC key and then push the 7 key.

keeping 
an eye on a distress frequency while scanning or searching another frequency band. 
 
Note: Depending upon the frequency and mode stored as priority, an audible click may be   
heard when the priority function is in operation. This is quite normal and is caused by the 
internal switching of circuitry necessary to accomplish the frequency change (as two 
frequencies cannot simultaneously be monitored).

Or, push the down arrow key to move to the next item on the configuration menu (IF

6-16 Configure IF output frequency 
The function enables you to tap the 2nd IF signal (10.7MHz) or the 3rd IF signal (455KHz) 
from the BNC (marked as 10.7MHz) type connector on the rear panel. The 10.7MHz of the 
2
nd IF signal is to be used with an optional SDU5500 or SDU5600 spectrum display unit for 
signal analysis. The bandwidth at 10.7 MHz is +/- 5 MHz from the center frequency (10 
MHz total)....

The function enables you to select the reference signal of the receiver. 
The AR-ONE has built-in a stable reference oscillator, however, an external high stability 10 
MHz reference (such as off-air atomic coupled) can be accepted from the SMA connector 
(marked as 10 MHz IN) on the rear panel of the AR-ONE. 
 
Push the down arrow key to move the cursor to “REF SEL” selection point.   
  
Use the main tuning dial or the right arrow key or the left arrow key to select the desired   
reference signal...

A multiple command entry is only valid where specified. Where a multiple command entry is 
allowed, each command MUST be separated with a space “h20” (HEX DECIMAL). Each 
command is completed and a [CR] or [CR][LF]. Although there is no local echo, either [CR] 
or specified response should come back from the receiver after confirming the correct 
command. If no response has been gained after a short while, the receiver has failed to 
receive the command...
