Planning the 75 All Road Installation

The 75 All Road CB includes an all-in-one handset, which allows you to communicate, change settings and operate the CB. It also includes the CB transceiver, which connects wirelessly via Bluetooth® to the handset. This provides flexible powering, mounting, and communication options, so you can mount your 75 All Road CB radio anywhere inside your vehicle. Before installing the 75 All Road CB, consider the power source you plan to use for the handset before selecting an installation location:

• Handset to CB (transceiver)
• Handset connected to the vehicle USB port
• Handset connected to the power adapter (included) for connection with the vehicle’s 12V power port

The handset is powered with a 5V USB connector, which can be plugged in and powered directly from any USB Type A port inside the vehicle or from the USB output on the front of the transceiver. This provides flexible powering options.

If you plan to connect the handset directly to the CB, you will need to consider a location closer to the handset. By mounting the handset away from the transceiver, you can install the transceiver under a seat, in the trunk, or anywhere inside the vehicle.

NOTE: Do not mount under the hood, near heat ducts, in direct line of the car’s heater or near gas and brake pedals.

Installation and Start-Up

Mounting the CB Transceiver (Black Box)

• Hold the Cobra 75 All Road black box in the exact location desired for mounting.
• Using it as a template, mark the location for the mounting screws (included).

NOTE: Make certain that nothing will interfere with the installation of the mounting screws before drilling holes.

• Drill and mount the black box as shown.

NOTE: Mounting the CB transceiver (Black Box) closer to the antenna will provide a better signal to the radio.

Connecting Wires

Using the 75 All Road CB requires antenna and hardwire installation.

• Connect the antenna cable plug (see Installing an Antenna before connecting).
• Install the provided hardwire.
• Connect the red wire (+) directly to the positive side of the battery or to a connection on the fuse box that is always on.
• Connect the black wire (—) to the negative side of the car, usually the chassis. Any other location with good electrical contact (paint removed) will also work.

NOTE: You must use a CB antenna (sold separately) with this radio. Antenna options are available on cobra.com. Please check your vehicle’s owner manual before installing and connecting the antenna and CB cables.

Installing the Handset Hanger

• Hold the microphone hanger in the location desired for mounting.

NOTE: Make certain that nothing will interfere with the hanger’s installation.

• Using it as a template, mark the location for the mounting screws (included).
• Drill and mount the microphone hanger.

CB Antenna

Since the maximum allowable power output of the transmitter is limited by the FCC, the antenna is critical to maximize transmission distance. Only a properly matched antenna system will allow maximum power output. Cobra loaded type antenna models are highly recommended for most installations. Consult your Cobra dealer for further details, or call 800-543-1608 and speak to a Cobra representative. A standard antenna connector is provided on the transceiver for easy connection. For optimum performance in passenger vehicles, the ideal antenna location is on the center of the roof. The second-best choice is on the center of the trunk (if available). Because many newer trucks feature fiberglass door skins, the outside mirror must be grounded to the chassis via a ground strap when the antenna is mounted on the mirror bracket. 3-way combination antennas are also available which allow operation of all three bands (AM-FM & CB), using a single antenna. However, this type of antenna usually results in less than normal transmit and receive range when compared to a standard-type “Single Band”. Cobra offers CB antenna and mounting solutions that can be purchased online. Please visit www.cobra.com, or if you’d like to speak with an expert, please call 800-543-1608 and our Customer Care Group can assist.

Installing An Antenna

Be sure the antenna is properly connected to the radio before transmitting. Prolonged transmitting without an antenna, or use of a poorly matched antenna, could cause damage to the CB. For the most reliable operation and maximum range, Cobra recommends using a vertically polarized, quarter wavelength whip antenna. Shorter, loaded-type whips are adequate when maximum range is not required.

NOTE: Mobile installations (cars, trucks, boats, etc) should be made only with a non-directional antenna system.

• A standard antenna connector (Type SO-239) is provided on the black box for easy connection to a standard PL-259 cable termination.
• Cobra antenna models are recommended; order directly from Cobra at www.cobra.com or contact your local Cobra dealer.
• For maximum efficiency in boat installations, a ground plane is required, unless the vessel has a steel hull. Consult your CB dealer for information regarding an adequate grounding system.

Installing an External Speaker

• Mount external speaker in desired location.
• Plug into the back of the CB transceiver. The external speaker should have 4-8 Ohms impedance and be able to handle at least 4 Watts.

NOTE: The external speaker is a Bridge Tied Load (BTL) design. Do not short the speaker wires to ground as it may damage the speaker amplifier.

TX NR (OFF – Level 05)

TX NR stands for Transmitter Noise Reduction and is a Digital Signal Processing feature of this radio. Enabling this feature will help further reduce background noise that the Handset microphone will pick up in a typical moving vehicle and send to the person on the other end. For the person on the receiving end, they will be able to hear your voice transmission more clearly from the All Road. For transmit noise reduction, the higher the level the greater the noise reduction. This should be used depending on the environment (noise level inside the vehicle). In a quiet environment, TX NR (or DSP) is not needed. To adjust Transmit DSP:

• Press and hold the ENT/MENU button on the All Road handset to active the MENU
• Use the UP button to select TX NR from the Menu Options

• Press the ESC button to get back to the home screen

NOTE: Use TX NR setting to help reduce the background noise for better speech intelligibility at the other CB radio station.

RX NR (OFF – Level 05)

RX NR stands for Receiver Noise Reduction. Enabling this feature will help to reduce radio noise sources picked up by the All Road receiver and improve the ability to clearly hear the voice of the person transmitting from the other end. RX NR works differently than TX NR where RX noise is environmentally created as a result of band conditions resulting in a lower signal-to-noise ratio, reducing speech intellibility. Adjusting RX NR or Receiver DSP will help to improve speech intelligibility and increase the signal to noise ratio that can greatly enhance the CB radio two-way communications experience. To adjust RX DSP:

• Press and hold the ENT/MENU button on the All Road handset to active the MENU
• Use the UP button to select RX NR from the Menu Options
• Use the UP or DOWN buttons select the Receive DSP level, press ENT to select
• Press the ESC button to get back to the home screen

NOTE: The level of DSP selected is based on personal preferences. Start on level 1 setting and listen to the current activity on the selected CB channel. If needed, increase the DSP level until an optimum setting is achieved or as desired. There are times when the CB band is fairly quiet. In those instances it may be more desirable to disable RX NR.
