NOTE:
If your SMX-4150 is equipped with SELCALL, refer to additional
instructions for correct operation.
TRANSMITTING
1. Turn the radio on and select the desired frequency by
pressing either of the channel select buttons until the channel
number is visible in the display.
2. Pick up the microphone and listen briefly to make sure that
no one else is using the channel, or with the microphone On-
Hook, depress the Monitor Button/LED 2 to monitor the
programmed channel for activity. The Monitor LED 2 should
be illuminated and the BUSY LED should be off.
3. Press the PTT bar on the microphone and from a distance
of 1/2 to 2 inches, speak into it directly in a normal tone of
voice. The TX LED will light while pressing the PTT.
4. Release the PTT bar as soon as you have completed the
transmission.
NOTE:
License requirements normally require that you monitor a
frequency for activity before transmitting.
TRANSMIT TIME-OUT-TIMER
The Transmit Time-Out-Timer is a dealer programmable option that
disables the radio's transmitter if a single transmission (i.e., an
uninterrupted depression of the PTT Bar) exceeds a predetermined period
of time. The time-out timer minimizes channel occupancy and battery
drain.
The radio reverts back to the receive mode, even with the PTT Bar being
depressed. Following the time-out period, a continuous alert tone is
generated that lasts until the PTT is released and the TX LED goes off.
Another transmission may be initiated immediately after releasing the PTT,
simply by depressing it again. If the PTT is released before the
predetermined time-out, the radio operates as normal (reverts to receive
mode with no alert tone).
