Motorola Alpha CB PRO - Radio User Manual

Introduction

The Motorola CB PRO operates on the Citizen Band Radio Service (CBRS) UHF frequencies. It requires no service fees or licenses, and can be used by anybody in Australia or New Zealand.

The CB PRO supports 40 channels. Channels 5 and 35 are designated for emergency communications ONLY, and non-urgent communications must be confined to the other channels. Channels 22 and 23 are receive only channels; thus, no voice transmissions are allowed on these channels.

Channels 1 to 8 designated as repeater output channels; Channels 31 to 38 are the corresponding designated repeater input channels. Channel 1 to 8 can be activated at a press of a button to operate in Talkaround mode (point to point, single frequency communications) when not used in the locality of repeaters.

Getting Started

Before you start using your radio, please make sure to do the following.

1. After unpacking your radio from the box, attach the battery and antenna to the radio as shown.
2. Charge your radio (see "Charging your Radio" for details).
3. Set the squelch level to a suitable level based on your environment (see "Squelch Level" at "Function Buttons (A, B, C, D)" or "Accessing Programming Mode Parameters" for more details).

NOTE: If a particular channel receives many unwanted calls coming from radios that do not belong to your communications group and are some distance away, or the "background noise" is excessive, you can try to filter out these transmissions by tightening the channel's squelch. However, tightening the squelch could cause calls from members of your communications group that are farther away to be filtered out as well.

Using PL and DPL Codes

PL and DPL codes allow you to create several communication groups within a single channel. All radios on that channel with the same set of PL/DPL Receive and Transmit codes are able to communicate with each other. In most cases, other radios on that channel not set with any code, or are set with different codes will not participate in the communications.

NOTE: PL/DPL codes do not offer complete privacy, as any radio user can listen into the communications on that channel by pressing the Monitor button.

You have a choice of selecting 001, 002, ..., 042, PL1, PL2, PL3 for PL codes, and 043, 044, ..., 126 for DPL codes. Please refer to the "Accessing Programming Mode Parameters" section for details in setting the PL/DPL Receive and Transmit codes for your desired channels.

Attaching and Removing the Antenna

To Attach Antenna

1. Fasten the antenna to the radio by placing the threaded end of the antenna into the Antenna Connector.
2. Rotate the antenna clockwise until tight.

To Remove Antenna

1. Turn the antenna in a counter-clockwise direction until it disengages from the radio.

Attaching and Removing the Battery

To Attach Battery

1. Fit the battery slots with the grooves on the radio.
2. Slide the battery upwards until a click is heard.

To Remove Battery

1. Slide the battery clasp away from the radio.
2. Slide the battery downwards.
3. Pull the battery away from the radio.

Attaching and Removing the Belt Clip

To Remove Belt Clip

1. Insert the end of a key between the release tab and the back surface of the radio.
2. Lift the release tab.
3. Slide the belt clip upwards.

To Attach Belt Clip

1. Align mounting rails of the radio with the grooves of the belt clip.
2. Slide the belt clip downwards until it clicks into place.

Charging your Device

1. Turn off your radio and the A/C power supply to your charger (if they are turned on).
2. Place your radio in the charger pocket.
3. Turn on the charger's A/C power supply.
4. Charge your radio until the charger's LED shows a steady green light (around 2 hours later).
5. Turn off the charger's A/C power supply, and remove the radio from the charger pocket.
6. Turn on your radio; you should see all 3 bars of the Battery Level Indicator illuminated.

Scan

Scan allows you to monitor multiple channels and receive calls that are transmitted on them.

During scan, when activity is detected that meets the unsquelch condition, the radio stops scanning and switches to that channel; the indicator is illuminated, and the channel number is displayed. When no activity is detected for a pre-set time, the radio resumes scanning.

The radio transmits on the Home Channel (the channel, the radio was monitoring, before the user activated scanning), if PTT is pressed during scanning. If the radio has stopped scanning, and changed to a particular channel, all transmit and receive activities is performed on that channel.

• Press the Scan button to begin channel scanning. The indicator blinks to indicate that the radio is scanning. The LCD Screen shows the Home Channel where the scan began.
• Press the + button to scan the channels in the ascending order, and the - button to scan in the descending order.
• Press Scan button to stop scanning.

Deleting a Nuisance Scan Channel

A channel with unwanted activity is called a Nuisance Channel. You can remove a Nuisance Channel from the scan list temporarily. To remove a Nuisance Channel

• Press the Nuisance Channel Delete button, when your radio stops on a Nuisance Channel. A highpitched tone is heard.

You cannot remove the Home Channel from the scan list. If attempted, a low-pitched tone is heard, and no action is taken.
To reinstate the deleted channel(s) into the scan list, restart scan, or simply turn off your radio and turn it on again.
