Number 4 should be it. I just looked up the manual and it does not list the tones. Here is what it says. "Selecting the Interference Eliminator Code
Interference Eliminator Codes help minimize interference by
blocking transmissions from unknown sources. Your radio has 121
Interference Eliminator Codes. Codes 1 – 38 are the standard analog
codes that appear on other FRS/GMRS radios. Codes 39 – 121 are
additional digital codes added for superior interference protection.
0 is the off position, no analog or digital codes are enabled.
And "
Note: You must set the Interference Eliminator Code to 0 on a radio
that uses Interference Eliminator Codes to communicate with radios
that do not have Interference Eliminator Codes. Select 0 for “no
tone, no code” and OFF will flash on your radio’s display.
Maybe this will help.
Actually its an 8 pin DIN on that radio. The KG-1000G uses an RJ45 and Buy Two Way Radios does have an extension cable for that radio but nothing listed for the KG-XS20G.
But it wouldn't hurt to give them a call and ask. You never know they may be able to make one.
Good luck!
