CONTROL BUTTON
The LAN Scout™ Jr. has a single button to both start a test and select other 
functions and options. Presses of less than about 1 second (short press) 
and more than 1 second (long press) are recognized differently.
1. 
Cable Testing (short press): With the LAN Scout™ Jr. off, each short 
press of the button causes a cable test to be executed and the results 
displayed for 20 seconds before powering off. “TEST” is displayed 
while testing is being performed. If another short press occurs 
before the 20 second time out another test and 20 second time out 
begin. If the button is pressed and held until “LOOP” is displayed and 
then released, tests are run continuously and the display updated. 
The LAN Scout™ Jr. will turn off automatically if there is no test 
result change for 5 minutes. A long press of the button will cause 
the LAN Scout™ Jr. to exit cable test loop mode and enter mode 
selection as discussed below.
2.
Mode Selection (long press): Starting with the LAN Scout™ Jr. off, a 
long press of the button will cause the LAN Scout™ Jr. to enter mode 
selection. In mode selection the LAN Scout™ Jr. cycles through cable 
test and tone generator modes. The mode displayed when the button 
is released will begin execution. From powered off, the modes in 
order are:
•	 LOOP: Cable test that loops continuously until it times out or 
is exited by a long press that reenters mode selection. Used to 
troubleshoot intermittent problems.
• Four Tone Cadences (Hi Lo 1, Hi Lo 2, Hi, Lo): The next four
modes are all tone generator modes with different sounds. The 
“Hi Lo” tones are made up of two frequencies with different 
timings. “Hi” and ”Lo” are single frequency. Once in a tone mode, 
short presses change the pins carrying tone. The pins with tone 
are displayed. In a tone mode, the Jr. will turn off automatically 
30 minutes after the last button press or by exiting to mode select 
with a long press.
• OFF: When the button is released with “OFF” displayed, the Jr.
will power off. Once in one of the above modes, OFF is the first 
mode offered upon exiting to mode select. To select a different 
mode other than OFF, continue to hold the button down and the 
next mode in rotation will be displayed next.
• CABLE: The cable test mode is the single cable test mode with 20
second timeout that a short press from powered off executes.
