Precautions
Pantum Regulatory Type/Model Number CDW-G4822BU-01; FCC ID:2AEGO4020WM 5G band I (5150-5350MHz) indoor use only. 5. Hereby, [Zhuhai Pantum Electronics Co., Ltd.] declares that the radio equipment type [CDW-G4822BU-01] is in compliance with Directive 2014/53/EU. The full text of the EU declaration of conformity is available at the following internet address: www.http:WWW.PANTUM.COM
FCC regulatory compliance statement
Statement 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. §15.21 Information
to user
Warning: Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
List of applicable FCC rules:
- 47 CFR Part 15, Subpart C 15.203
- 47 CFR Part 15, Subpart C 15.205
- 47 CFR Part 15, Subpart C 15.207

- 47 CFR Part 15, Subpart E 15.407
Summarize the specific operational use conditions
This module can be used in IoT devices, the input voltage to the module is
nominally 5V. Only the embedded integral antenna is allowed. Any other
external antenna is prohibited.
Limited module procedures
This module is not a limited module.
Trace antenna designs
The antenna is not a trace antenna.
RF exposure considerations
This Module complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
a minimum distance of 20cm between the radiator and your body. This
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
Antennas
If you desire to increase antenna gain and either change antenna type or use
the same antenna type certified, a
Class II permissive change application is required to be filed by us, or you
(host manufacturer) can take responsibility through the change in FCC ID (new
application) procedure followed by a Class II permissive change application.
Label and compliance information
Please notice that if the FCC identification number is not visible when the
module is installed inside another device, then the outside of the device into
which the module is installed must also display a label referring to the
enclosed module. following: “Contains FCC ID: 2AEGO4020WM” any similar wording
that expresses the same meaning may be used. § 15.19 Labelling requirements
shall comply on end-user device.
Labeling rules for a special device, please refer to §2.925, § 15.19 (a)(5),
and relevant KDB publications. For E-label, please refer to §2.935.
Information on test modes and additional testing requirements
The OEM integrator is responsible for ensuring that the end-user has no manual
instruction to remove or install-module. The module is limited to installation
in mobile applications, a separate approval is required for all other
operating configurations, including portable configurations with respect to
§2.1093 and different antenna configurations.
Additional testing, Part 15 Subpart B disclaimer
This modular transmitter is only FCC authorized for the specific rule parts
listed on our grant, host product manufacturer is responsible for compliance
to any other FCC rules that apply to the host not covered by the modular
transmitter grant of certification. The host manufacturer in any case shall
ensure host product that is installed and operating with the module is in
compliance with Part 15B requirements. Please note that For a Class B or Class
A digital device or peripheral, the instructions furnished in the user manual
of the end-user product shall include the statement set out in. §15.105
Information to the user or such a similar statement and place it in a
prominent location in the text of host product manual. Original texts as
follows: For Class B
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 to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If 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.
