  • Page 6 RCI-2985 CHAPTER 3 RCI-2995 INTRODUCTION 11. PHONE JACK Accepts a plug from a headset of 4 to 32 Ohm impedance. Insertion of the plug will disable the built-in speaker and external speaker connected to External Speaker jack. 12. RF/SWR METER Used for two purpose - to indicate approximate transmitter power when transmitting and antenna SWR (standing wave ratio).

    RCI-2985 CHAPTER 3 RCI-2995 INTRODUCTION 3.1.2 PROGRAMMING KEY PAD 16. NB/ANL/OFF SWITCH In the NB/ANL position, the RF Noise Blanker and the Automatic Noise Limiter in the audio circuits are also activated. The Noise Blanker is very effective in eliminating repetitive impulse noise such as ignition interference.
  • Page 8 RCI-2985 CHAPTER 3 RCI-2995 INTRODUCTION 23. LOCK BUTTON (LOCK) This button is used to lock a selected frequency. Press it to activate the switch. In this position, it disables the Frequency Selector Control, up/down buttons on the front control panel and remote up/down buttons on the microphone.

  • Page 9: Frequency Selection

    3.3 OPERATION 3.3.1 CHANNEL SELECTION Frequency selection for the RCI-2985DX / RCI-2995DX is simple. Select a desired operating frequency by rotating the Frequency Selector, or using the (σ) Up and (τ) Down buttons on the front panel or the microphone. Press the LOCK button to lock into the selected frequency. This will disable the Frequency Selector and the up/down buttons on the front panel and the microphone.
  • Page 10 If - split is selected, the transmit frequency will be lower than the receive frequency. 3.3.6 MEMORY FUNCTION The RCI-2985DX / RCI-2995DX can store up to 10 most frequently used frequencies (from 0 to 9). To program a frequency into memory, follow the procedure described below: (1) Press the MAN button.
  • Page 11 (5) To stop scanning a certain channel, press the MAN button, or turn the Squelch knob counterclockwise until you hear the receiver noise. 3.3.8 METER The meter built into your RCI-2985DX / RCI-2995DX on the left hand side of the LCD display provides the following information: 1. SIGNAL/MODULATION METER In transmit mode, it provides a visual indication of modulation percentage when transmitting in the AM mode and received signal strength on the receive mode.
  • Page 12 RCI-2985 CHAPTER 3 RCI-2995 INTRODUCTION (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.

    10 and 12 meter dual band base station transceiver. 4.1 FREQUENCY SELECTION Frequency selection in the RCI-2985DX / RCI-2995DX can be accomplished using anyone of the three following methods: (1) The first method of frequency selection is through the use of the SHF (Shift) key and the (σ) Up and (τ) Down arrows.
  • Page 14 4.2.2 MEMORY SCANNING The RCI-2985DX / RCI-2995DX has 10 non-volatile (i.e. memory resident) memory locations which can be programmed with any available frequency within the operating band of the radio. The scan function of the unit can be programmed to scan these memory channels. The radio will then scan only those memory channels which have been programmed.

  • Page 15: Offset Frequency Operation

    4.3 OFFSET FREQUENCY OPERATION The RCI-2985DX / RCI-2995DX has an offset or split frequency feature that will permit the radio to be operated in a half-duplex mode. This will allow the user to talk on FM repeaters operating in the 10 and 12 Meter dual band.
