Authorization and Evaluation Division

Subject: Declaration of compliance to the requirements of §15.121

7435 Oakland Mills Road

Columbia, MD 21046

FCC ID: 2AZVIJC-3518

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.

Sincerely Yours,

Signature:
