key. The current setting will be displayed with T/SQ/
DCS icons and relative frequency/code. Press the same key to
select T/SQ/DCS setting.
The numbers (such as 88.5) represent the CTCSS frequency in
2.
Hz. When it is displayed with the
icon only, the unit transmits
the sub-audible tone while the PTT
is pressed (encode) and the repeater
access is e n a b l e d (assuming the
repeater is using 88.5Hz tone).
Press the same key again so that the
3.
icon shows up on the display.
This is the CTCSS decode frequency.
This enables CTCSS squelch (or Tone
Squelch, TSQ).
Press it again so that the 3-digit number
4.
and
icon is displayed. This is the DCS code, and it enables
DCS encoding and decoding.
Many repeaters require a CTCSS tone or a DCS code encode
setting as a “key” to access the system, so-called “selective-calling”.
Sometimes, CTCSS or DCS decode features are used on the output of
a repeater so they can be used as a squelch. In this mode, regardless
of the main squelch status, the audio can be heard ONLY when the
matching tone/code signal is received. The combination of CTCSS
squelch and DCS function is not available; only one or the other may
be used for a given channel.The operation is available on VFO and
memory mode. Dealer-Preprogrammed units can't operate this function
manually. In the memory mode, the setting is temporary; changing the
channel or turning off the radio will erase the setting.
