antenna are properly connected.
2. Turn the VOL/PWR knob clockwise to turn the transceiver on.
3. Turn the SQL knob fully counterclockwise. This state is known as "squelch off".
4. Turn up the VOL knob until noise or audio from the speaker is at a comfort-
able level.
5. Turn the SQL knob clockwise until the random noise disappears. This state
is known as the "squelch threshold."

4. Speak slowly and clearly into the microphone.
We recommend that the duty cycle (TX:RX) is "1 : 3" or less.
5. When the transmission is finished, release the PTT switch.
This is a noise cancelling microphone. The oval slot on the bottom of
microphone should be positioned within 1.5 cm from the mouth for opti-
mum performance.
8.3 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.
When a transmission was shut down by the TOT, the GX1100E can not
transmit afterwards for 10 seconds.
