Antenna
The module uses embedded PCB track Tri-Band antennas. RX and TX diversity
antennas are used to avoid dropouts due to multipath fading.
The antenna has a 3 dB gain.
- Antenna A (ANT A) fixed track antenna on the module
- Antenna B (ANT B) fixed track antenna on the module
Only ‘one’ antenna is selected for use at any one time, through the onboard Transmit-Receive/ Diversity RF switch.
Transceiver dimensions
- Module -size: 35 x 35 x 4.3 mm (±0.15), including 2-Printed Tri-Band antennas.
- Diameter mounting holes: 3.0 mm (±0.05).

Firmware revision
The firmware version is: V2.3
This firmware might be updated and used for newer products, though not
scheduled or intended.
Module labeling
To acknowledge and reference the FCC and IC DWAM83TB module approval, the
following text shall be visible on the label of the host product:
Contains FCC ID: ZUC-DWAM83TB
Contains/Content IC: 23522- DWAM83TB
FCC Statement
Applicable FCC rules
FCC CFR 47 Part 15C – Frequency Hopping Transmitters / Digital transmission
systems.
FCC CFR 47 Part 15E – Unlicensed National Information Infrastructure Devices.
FCC Statement
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions:
- This device may not cause harmful interference, and
- this device must accept any nterference received, including interference that may cause undesired operation.
Any changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
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.
This module is only FCC authorized for the specific rule parts listed on the
grant. Any product manufacturer that decides to integrate this module into a
host product is responsible for compliance with any other FCC rules that apply
to the host not covered by the modular transmitter grant of certification. Any
host product is still required to comply with FCC CFR 47 Part 15 subpart B
with this module installed.
IC Caution
This device complies with Industry Canada license-exempt RSS standard(s).
Operation is subject to the following two conditions:
- This device may not cause interference and
- this device must accept any interference, including interference that may cause undesired operation of the device.
This equipment should be installed and operated with a minimum distance of 20
cm between the radiator and your body.
