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 to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful inter-

ference to radio or television reception, which can be determind by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the follwing 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 changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This device complies with Part 15B of the FCC Rules. Operation is sub-

ject 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. WARNING: MODIFICATION OF THIS DEVICE TO RECEIVE CELLULAR RADIOTELEPHONE SERVICE SIGNALS IS PROHIBIITED UNDER FCC RULES AND FEDERRAL LAW.

Block 39-1, Optoelectronics-information industry base, Nanan, Quanzhou, Fujian, China TYT ELECTRONICS CO., LTD Date: Dec. 31, 2019 PHOENIX TESTLAB GmbH Product Certification Knigswinkel 10 D 32825 Blomberg FCC ID: POD-ADB5 Subject: Declaration of compliance to the requirements of 15.121 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. If you have any questions, please feel free to contact me. Thank you. Sincerely, Signatory
