STANDARD GROUP CALLS

4. Press (and hold) the microphone PTT (push-to-talk) switch to talk and
release it to listen. Operation with LTR-Net, LTR, and conventional
calls is as follows:
LTR-Net and LTR Operation
• If tones are enabled, the proceed tone sounds shortly after the PTT
switch is pressed if the radio system was successfully accessed (see
page 27). If tones are not enabled, no tone sounds when the system
is successfully accessed.
• If the radio system is busy, the busy tone sounds (see page 53) and
“BUSY” is indicated in the display. Additional access attempts as
long as you continue pressing the PTT switch.
• If the radio system could not be accessed because of an out-of-range
condition or some other reason, the intercept tone sounds (see
page 53) and “NO ACCES” is indicated in the display. The PTT
switch must then be released and pressed again to make another
access attempt.
• When responding, busy or no access conditions may also occur the
same as when placing a call because the system is re-accessed for
each transmission with these calls.
Conventional Operation
• If the channel is busy and the Transmit Disable On Busy feature is
programmed (see page 51), “DSBL BSY” is indicated in the display
and the transmitter is disabled. Any channel activity is heard while
the PTT switch is pressed.
• Otherwise, busy and out-of-range conditions are not indicated and
speaking can begin when the PTT switch is pressed (if the channel is
not busy). If the proceed tone is enabled on conventional systems, it
indicates when speaking can begin but does not indicate that the
channel is free or has been successfully accessed.
