Ranger RCI-2950DX Installation, Operation, Transceiver Mounting, Power Connection, Front Panel

Chapter 3 Installation

The RCI-2950DX/2970DX-150 is easy to install. All necessary parts (less the antenna and coax cable) have been included to facilitate installation.

Transceiver Mounting

Choose a suitable location for the transceiver that will allow easy access to the front panel as well as proper air circulation to the back of the unit. If you are installing the unit in a vehicle, attach the mounting bracket first, then attach the transceiver to the mounting bracket using the hardware provided. Before making any electrical connection, ensure that the transceiver is turned off and the vehicle's battery is disconnected.

Power Connection

The transceiver operates off of any 12 to 13.8 VDC source. Beware of voltage drops caused by operating from Cigarette Lighter Plugs or long DC wire runs. Sometimes it is best to connect direct to the battery for best RF output and Tx audio quality

NOTE

The condition of a vehicle's electrical system can affect the operation of your RCI-2950DX/2970DX-150. A low battery, worn generator/ alternator, or poor voltage regulator will impair performance of the unit as well as the vehicle.

If an AC power supply is used with your radio, it must be regulated and rated for at least 7 Amps continuous for the RCI-2950DX and 20 Amps continuous for the RCI-2970DX-150. Low voltage while under load will cause reduced receiver gain and low transmitter output with possible distortion and splatter.

CAUTION

Voltage above 15 VDC will damage the unit. Be sure to check the source voltage before connecting the power cord.

Chapter 4 Operation

Front Panel

1.FREQUENCY SELECTOR: Used to set the desired transmit and receive frequency. The frequency is digitally displayed in the LCD window next to the selector. The FREQUENCY SELECTOR knob next to the LCD display, allows changing each digit on the frequency display by first placing the frequency display cursor (using SHF button) below the desired digit and then turning the selector knob.

2.RF POWER CONTROL: This control adjust the Transmitter’s RF power output level.

3.MIC GAIN CONTROL: This feature adjust the microphone gain for the transmit and PA modes. Experiment with this control for the setting that will provide best audio quality. Avoid over-modulation, which causes interference to adjacent stations and “splatter”.

4.ON/OFF VOLUME CONTROL: Turn clockwise to apply power to the radio and to set the desired listening level.
