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: “ ” icon is not shown) by pressing the key.
5. When receiving a signal, wait until communications
stops before transmitting.
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.
WATER ENABLED LIGHT
When the HX300 comes in contact with water a red light will blink to
assist retrieving it in low light conditions. The light will automatically
turn off in about 15 seconds when it is removed from water.
The HX300 has a menu selection to enable, disable and select differ-
ent blinking light times. Refer to Menu Mode Item “ FL (WATER EN-
ABLED LIGHT)” on page 33 for details.
