Squelch Setting

SQ_SQ: Signal strength monitoring squelch setting

This function is used for squelch level setting, but it detects the strength of received signal, and better strength means a better signal. It is divided into 29 levels (0.F~2.8), 0.F is the lowest level, and 2.8 is the highest level. For example, when set to 2.8, the audio channel can only be turned

on when the received signal reaches its maximum. (In an experiment, the noise adjustment

range of SQ_SQ is obviously larger than SQ_AQ. We recommend using SQ_SQ as the first choice, as SQ-SQ and SQ-ASQ can’t work at the same time. One will stop working when the other one is running.)

Operation instructions:

1. Enter: short press the SQ button, the screen displays “sq” for one second, and then display

the current SQ level. At this time, the SQ level can be adjusted by pressing UP and DN.

2. Exit: After the adjustment is completed, you can press SQ again to exit the SQ setting mode,

or you can automatically exit the SQ setting mode and enter the waiting mode. Keep it for a while without any operation will also exit the SQ setting..

SQ_ASQ: Noise monitoring squelch setting.

This function is also used for squelch level setting, but it detects the noise of received signal, and the smaller the noise, the better the signal. It is divided into 9 levels (A1~A9), A1 is the lowest level, and A9 is the highest level.

Operation instructions:

1. Enter: Long press the SQ button, the screen displays the AQ icon and the current ASQ level. Short press the SQ button or wait for a while, back to waiting mode, the AQ icon will still light up. When SQ_ASQ is in waiting mode, short press SQ will return to SQ_ASQ setting status.

2. Exit: When the SQ_ASQ function is on, long press SQ will exit.

Modulation Selection

Depending on the selected frequency range and the selected channel, the device supports FM (Frequency Modulation) and AM (Amplitude Modulation) modes.

Long press [A/F] key to select AM mode and FM mode. However, such a change is only possible

if the set channel is also allowed in the respective operating mode. This function is only available

for European version.

The respective operating mode is indicated on the LC display with "AM" or "FM" to the left of the channel number.

RF Gain Control Function

This function will affect the strength of signal reception.

1. Enter: short press [RFG] key to enter. After entering, the screen will display current RFG level, you can press [UP] and [DN] keys to adjust RFG level. The RFG level is not a continuous

number but “6”, “12”, “18”, “24”, “30”, “36”, “42”, “48” a total of 8 levels. When the RFG function is turned on, the signal reception intensity will be attenuated. The higher the level is, the

greater the attenuation. After completing the setup, wait for a while and the radio will automatically go to the waiting mode and display the “R” icon on the screen.

2) Exit: short press [RFG] key to enter RFG setting mode, and short press RFG again will exit

the RFG function.

Emergency Channel Switching

Operation: short press [EMG] key to switch between “the current channel’’, “19th channel”,

“9th channel”.

1. Short press EMG] key to switch 9th channel

2. Short press [EMG] key again to switch 19th channel.

3. Short press [EMG] key third time to return to last normal channel.

Keyboard Lock

1. Enter: long press [EMG] button to enter the locked status. In locked status, nothing happens

except for pressing the PTT button.

2. Exit: In the locked status, long press [EMG] again will exit the EMG_LC function.

Scan function

1. In the waiting status, a short press of [A/F] key will enter the scan mode.

2. The CB radio will scan all channels of the mode in 2 channels per second. When the scanned channel has a signal and the signal strength reaches the SQ or ASQ setting, the speaker will

transmit the sound, automatically stop scanning, and maintain the current channel.

3. When the channel signal disappears or decreases to not meet SQ/ASQ requirements, the CB

radio will continue to scan. Short Press [A/F] key again or press transmit will exit scan mode.

Norm Selection

This CB radio supports multiple frequency bands. Depending on the country in which the device is operated, it may be necessary to choose a different frequency band. This function is only

available for European version.

1. For changing the current norm, please hold [A/F] key while turning the radio on. The current

norm appears in the display.

2. Use the channel selectors [UP] and [DN] keys of the microphone to set a different norm

3. Confirm your selection by turning the radio off and on again. For further frequency band information see Appendix C.

Regarding the permissions and restrictions of the individual norms in the various European countries, please check the radio passport, which is included in the scope of delivery. The user is solely responsible for the selection of the permissible norm in the country of operation.

Install External Microphone

The microphone is fixed to the radio, it cannot be removed. It contains the PTT key, as well as

the channel selectors [UP] and [DN] keys.

Chapter 3 - Basic Operation

Chapter 4 - Trouble Shooting Guide

Quick Start Guide

1. Open the box carefully and remove the radio, the cable and the microphone.

2. Connect the SO-239 socket of the radio to a corresponding antenna via a PL-259 plug. You will need to purchase an antenna to operate the radio.

3. Connect the power supply cable to an appropriate 12V DC power source.

This should be able to supply at least 5A continuous current.

4. Turn ON/OFF switch clockwise and set the volume to a medium level.

5. Use the channel selector keys [UP] and [DN] at the microphone for channel selection.

The actual channel is displayed on the LCD.

6. Press the [PTT] key and talk to her! If necessary, use VOL knob to adjust the volume of the

built-in speaker.

The Radioddity CB-27 is a cost-effective CB analog radio. It can communicate with any other CB analog radio but without spending an exorbitant amount of money on it! You only need to make sure that you are on the same channels with the same modulation type.

Why can't this CB radio communicate with my other two way radios? a) Make sure that the two radios are on the same channel. b) Check if the same channel is set to receive the same type of modulation. c) Check if the volume of the two radios is high enough d) Check the correct installation of the antennas e) Check the talking range of the radios.
