GX5000S / GX5500S Operating Manual
1. Perform steps 1 through 6 of RECEPTION.
2. Before transmitting, monitor the channel to ensure it is clear.
3 Press the PTT (push-to-talk) switch. The “” indicator in the LCD is displayed.
4. Speak slowly and clearly into the microphone.
5. When the transmission is finished, release the PTT switch.
NOTE
This is a noise-canceling microphone. The oval slot on the bottom of microphone should
be positioned within 1.5 cm from the mouth for optimum performance.
10.3 TRANSMIT TIME - OUT TIMER (TOT)
When the PTT switch on the microphone is held down, transmit time is limited to 5 minutes.
This limits unintentional transmissions due to a stuck microphone. About 10 seconds before
automatic transmitter shutdown, a warning beep will be heard from the speaker(s). The
transceiver will automatically go to receive mode, even if the PTT switch is continually held
down. Before transmitting again, the PTT switch must first be released and then pressed
again.
NOTE
When a transmission was shut down by the TOT, the GX5000S/GX5500S can not transmit
afterwards for 10 seconds.
