-To help quiet (squelch) unwanted signals, FRS radios have the option of transmitting a CTCSS tone or DCS code (AKA: "PL tones", or "sub-audible tones").  These are low "bass notes" or digital information that the radio transmits on top of the voice, but which can't really be heard.  If the receiver is configured to expect a specific tone/code, it will keep the speaker squelched unless that tone/code is detected.  This is useful to ignore chatter from others on a busy channel, but if two radios with different tones transmit at the same time on the same channel, they will interfere with one another.

 K0TFU has a really good article explaining all of this for FRS radios: [[https://www.k0tfu.org/deep-dives/frs-gmrs-privacy-codes-demystified |FRS/GMRS Privacy Codes Demystified]], and [[/hambasics/sections/vhfops#squelch |our own site]] goes a little deeper in the context of ham radios.

 Refer to the user manual for specific instructions, but in general, you should:
   * Disable the //CTCSS/DCS// on all 22 channels.  On the Revetis RB48, the CTCSS/DCS is represented by a number between ''1'' and ''121'' (on the right).  The number ''0'' means that CTCSS or DCS is disabled.

   * Disable //VOX//, which is an option to transmit without pressing the PTT.
