Using the Continuous Tone Coded Squelch System (CTCSS)
Privacy Codes
This feature allows you to ignore transmissions from other trans-
ceivers that are using the same channel. One of 38 privacy codes
may be selected. The same code must also be selected on those
transceivers which you desire to communicate with. When in use,
the transciever will play only strong signals from other FRS units set
to the same code number. Keep in mind, however, that this feature
does not prevent others from listening to your transmissions. To
activate or deactivate the CTCSS mode, press and hold the call
button for 2 seconds, this will toggle the mode on or off. Upon acti-
vation the current privacy code number will be displayed to the right
of the current channel number on the LCD and will flash for 5 sec-
onds to allow its adjustment. If no CTCSS number is displayed this
indicates that the system is off.
To select a CTCSS code number, activate the system as described
above and use the up or down keys to adjust the code number. If
the CTCSS mode was already active, a momentary press of the
call button will cause the current CTCSS number to flash on the
LCD, allowing its adjustment. The FR-314 will return to its standby
state if no buttons are pressed for 5 seconds, or if the call or PTT
buttons are pressed. See the table at the end of this manual for the
CTCSS frequency assignments
