After the frequency measurement is completed, you can communicate with the target walkie-talkie. Specific Steps: On the first channel, press and hold [PTT] + side key 2 to power on. After entering the mode, the transmitter light will flash continuously, accompanied by three 'beep beep beep' sounds and the current channel will be announced, indicating that the code-breaking mode has been entered. In this mode, the target walkie-talkie needs to transmit, and the device will receive and break the code. If the code breaking is successful, the transmitter CA-10 Operation Side Button 1 / Side Button 2 After powering on, the default volume mode is used. Short presses of side buttons 1 and 2 can be used to adjust the volume. Short press of side button 1 increases the volume; short press of side button 2 decreases the volume. Short press the power button to switch to channel mode. Side buttons 1 and 2 are used to select the channel. When you have set the operation functions of side buttons 1 and 2 through the programming software, you need to long press side buttons 1 and 2 to activate this function.

After success, you can talk to the target walkie-talkie to verify whether the code breaking was successful. In code breaking mode, a short press of side button 2 will produce a "beep" sound, indicating that the code breaking has been restarted. If the code breaking is unsuccessful for a long time (more than 10 seconds), please press the button briefly to restart the code breaking. A long press of side button 2 will exit the code breaking mode (exiting the code breaking will be indicated by two "beep" sounds). This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received,including interference that may cause undesired operation. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference in radio communications. However, there is no guarantee that interference will not occur in a particular situation. lf this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help.

SkyConnex Communications Limited Room 3601, 36/F Lippo Centre, Tower Two, 89 Queensway, Hong Kong Date: 2026-04-16 Declaration Letter FEDERAL COMMUNICATIONS COMMISSION Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Subject: Declaration of compliance to the requirements of §15.121 FCC ID: 2BSIICA-10 Dear Sir/Madam, We declare that, this scanning receiver is incapable of operating (tuning), or readily being altered by the users to operate, within the frequency bands allocated to the Cellular Radiotelephone Service in part 22 of this chapter (cellular telephone bands). This device will not be able to receive transmissions in the cellular telephone bands by means of clipping the leads of, or installing, a simple component such as a diode, resistor or jumper wire; replacing a plug-in semiconductor chip; or programming a semiconductor chip using special access codes or an external device, such as a personal computer. This device is also incapable of converting digital cellular communication transmissions to analog voice audio. This device is designed so that the tuning, control and filtering circuitry is inaccessible. Any attempts to modify the equipment to receive transmissions from the Cellular Radiotelephone Service will render the receiver inoperable. This scanning receiver rejects any signals from the Cellular Radiotelephone Service frequency bands that are 38 dB or lower based upon a 12 dB SINAD measurement. We are aware that the modification of this device to receive transmissions from Cellular Radiotelephone Service frequency bands will be considered to constitute manufacture of such equipment. This includes any individual, individuals, entity or organization that modifies one or more scanners. Any modification to receive transmissions from the Cellular Radiotelephone Service frequency bands voids the certification of the scanning receiver, regardless of the date of manufacture of the original unit.
