Functions two and three are used to set
Busy Channel operation. There are three
types of busy channel operation available.
They are described more fully under “Busy
Channel” in the Owner’s Manual.
busy channel modes include:
busy channel Indicator - The yellow LED illuminates when a
signal is received on the channel selected, with or without the
programmed receive Code Guard setting.
busy channel lockout - The yellow LED illuminates and the
transmitter PTT is disabled when a signal is received without the
programmed receive Code Guard setting.
busy channel override - This function is similar to Busy Channel
Lockout except the transmitter PTT can be activated by rotating the
Squelch knob clockwise off the Code Guard detent.
To set Busy Channel operation, use the following chart:

When function 4 is enabled (flashing) the
ANI ID number will be transmitted (as a
DTMF tone sequence) with each press of
the PTT switch. See “Automatic Numeric
Identification (ANI)” on page 5 of this manual
for instructions on setting the ANI number.
When function 5 is enabled (flashing) the keypad becomes active for
manual DTMF operation.
When functions 4 and 5 are both enabled (flashing) the ANI tone
sequence will be transmitted only after the [ENT] key is pressed while
the transmit PTT switch is activated. A sidetone of the ANI number
transmitted will also be heard through the speaker.
