Coded Squelch Operation (Conventional Channels Only); Smart Ptt (Conventional Operation Only) - Motorola MTX150 User Manual

CODED SQUELCH OPERATION
(CONVENTIONAL CHANNELS
ONLY)
Tone Private-Line (PL), Digital Private-Line
(DPL), and carrier squelch operation are all
available in your radio, on a per-mode basis.
When in carrier squelch operation, all traffic on
the mode is heard. When in PL or DPL
operation, your radio responds to only those
messages intended for you. When this feature
is mode-slaved, PL, DPL, or carrier squelch is
programmed to each mode.
SMART PTT (CONVENTIONAL
OPERATION ONLY)
This feature is programmable by your
authorized Motorola dealer.
Smart PTT is a per-mode feature which gives
the system manager better control of radio
operators. When Smart PTT is enabled in your
radio, you cannot transmit on an active mode.
Three radio-wide variations of Smart PTT are
available.
• Transmit Inhibit on Busy Mode—you are
prevented from transmitting if any activity is
detected on the mode.
• Transmit Inhibit on Busy Mode with
Wrong Squelch Code—you are prevented
from transmitting on an active mode with a
squelch code other than your own. If the PL
code is the same as yours, you are allowed
to transmit.
• Quick-Key Override—This feature can
work in conjunction with either of the two
above variations. This feature allows you to
override the transmit-inhibit state by quick-
keying (two PTT button presses within a
programmable period -- the default is one
second -- of each other) the radio.
Note: If you try to transmit (press the PTT
button) on a Smart PTT mode that is
busy, a continuous alert tone is gener-
ated until the PTT button is released;
the transmission is inhibited.
• The red LED blinks when the radio is
receiving indicating that the mode is
busy.
