6.4 TRANSMISSION
1. Perform “ 6.3 RECEPTION” discussion above.
2. Before transmitting, monitor the channel and make sure it is clear.
THIS IS AN FCC REQUIREMENT!
3. For communications over short distances, press the
key to select the Low power (1 watt: “ ” icon ap-
pears).
Note: Transmitting on Low power prolongs battery life. Low power should
be selected whenever possible.
4. If using Low power is not effective, select High power (5
watts (for HX150) or 2.5 Watts (for HX100): “ ” icon is
not shown) by pressing the key.
5. When receiving a signal, wait until communications stops before trans-
mitting.
NOTE
The transceiver cannot transmit and receive simultaneously.
6. Press the PTT (Push-To-Talk) switch to transmit. Dur-
ing transmission, the “ ” indicator will appear on the
display.
7. Position your mouth about 1/2 to 1 inch (1.2 ~ 2.5 cm) away from the mic
hole on the top right above the display. Speak slowly and clearly into the
microphone.
8. When the transmission is finished, release the PTT switch.
6.4.1 TRANSMIT TIME - OUT TIMER (TOT)
While the PTT switch is held down, transmission time is limited to 5 minutes.
This prevents prolonged (unintentional) transmissions. About 10 seconds
before automatic transmitter shutdown, a warning beep will sound from the
speaker. The transceiver automatically switches to the receiving mode, even
if the PTT switch is held down. Before transmitting again, the PTT switch
must first be released, then wait 10 seconds and then pressed again. This
Time-Out-Timer (TOT) prevents a continuous transmission that would result
from an accidentally stuck PTT switch.
