Wave Ratio) meter allows you to measure your antenna condition. To operate this function, connect
your antenna to the transceiver antenna connector, set the mode switch to AM and adjust the MIC Gain
to minimum. Select a frequency near the middle of the band you plan to use most. Activate the SWR
function and press the PTT button on the microphone. A bar on the meter is an indication of the
antenna matching. If there is no bar, it indicates that your antenna system is perfectly matched. The less
bar, the better matched. If several bars appear, your antenna needs adjusting. The SWR function is self
calibrating.
3.3.9 CTCSS - OPTIONAL
The RCI-2985DX / RCI-2995DX can operate with CTCSS frequencies for accessing repeaters, with an
optional CTCSS (Continuous Tone Coded Squelch System) encoding device installed.
3.3.10 PROCEDURE TO RECEIVE
(1) Be sure that the power source, microphone and antenna are connected to the proper connectors
before going to the next step.
(2) Press the POWER switch to apply power to the transceiver.
(3) Set the VOL. to a comfortable listening level.
(4) Set the MODE switch to the desired mode.
(5)
Listen to the background noise from the speaker. Turn the SQUELCH knob slowly clockwise until
the noise just disappears. The SQUELCH is now properly adjusted. The receiver will remain quiet
until a signal is actually received. Do not advance the control too far or some of weaker signals will
not be heard.
(6) Set the CHANNEL selector switch to the desired channel.
(7) Set the RF GAIN control fully clockwise for maximum RF gain.
(8) Adjust the CLARIFIER control to clarify the SSB signals or to optimize AM/FM signals.
3.3.11 PROCEDURE TO TRANSMIT
(1)
Select the desired channel of transmission
(2) Set the MIC GAIN control fully clockwise.
(3) If the channel is clear, depress the push-to-talk switch on the microphone and speak in a normal
voice.
