Note that you can use any other memory as a priority channel in place of memory 1
in the above procedure when operation is to be on the Dial.
Tone Squelch Operation
The FT-212RH includes a CTCSS encoder (for transmitting), and can also be used
to silently monitor for calls on busy channels when the optional FTS-12 Tone
Squelch Unit is installed. The encode function superimposes a subaudible tone (at a
frequency too low to be heard) on the transmitted carrier, while the decode
function (of the FTS-12) monitors receiver audio through a narrow filter at the
same subaudible frequency, keeping the squelch closed until a matching tone is
received. Installation instructions for the FTS-12 are in the 'Installation' chapter.
To check or set the CTCSS tone frequency, press [F]+TONE. The tone frequency
will be displayed (in Hz), with a leading zero if that tone selection is a high-Q
type. To change the tone frequency, rotate the selector knob or press the
microphone DWN/UP keys until the display shows the tone frequency you require
(the display will step through the standard EIA tones, plus 97.4 Hz). Press TONE
to return to the operating frequency display when the tone frequency is selected.
To activate tone squelch press TONE. 'ENC' (encode) will be displayed and the
tone generator will be activated for transmission. Press TONE again and both
'ENC' and 'DEC' (decode) will be displayed together as tone squelch is activated
for both transmission and reception (only if the FTS-12 is installed: a matching
tone frequency will open the squelch). Pressing TONE once more disables tone
squelch features.
Once you have the tone squelch set up the way you want it, you can store it in any
memory. Afterwards, to change a memory, just recall it, reset the tone frequency or
function, and store the memory again (press and hold F/WRITE 0,5 second, and
then press it again momentarily.
