4. Layout and Soldering Considerations

Unit: mm

Unit: mm

To make sure wireless performance is at its best condition, please layout the module on the carrier board
as below instructions.

4.1 Carrier board under the antenna area of the module like the picture;

4.2 Keep out enough area for the antenna area;

4.3 Reflow profiles are to be selected according to standard manufacturing process;

4.4 The soldering temperature should be less than 206℃;

4.5 The module should be placed far away other low frequency and digital circuits;

4.6 The MS50 series modules contain highly sensitive electronic circuitry and are Electrostatic Sensitive
Devices (ESD). Handling the MS88 series modules without proper ESD protection may destroy or
damage them permanently.

*PCB: It’s the mother board / carrier board.

FCC Caution: Any changes or modifications not expressly
approved by the party responsible for compliance could void the user's
authority to operate this equipment.
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.
This device and its antenna(s) must not be co-located or operating in conjunction
with any other antenna or transmitter.

15.105 Information to the user.
(b) For a Class B digital device or peripheral, the instructions furnished the
user shall include the following or similar statement, placed in a prominent
location in the text of the manual:
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.

The device has been evaluated to meet general RF exposure requirement. The device can be used in portable

exposure condition without restriction.

Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The
module should not be installed and operated simultaneously with other radios except additional RF exposure
was evaluated for simultaneously transmission.
The availability of some specific channels and/or operational frequency bands are country dependent and are
firmware programmed at the factory to match the intended destination.
The firmware setting is not accessible by the end user.
The final end product must be labelled in a visible area with the following:

“Contains Transmitter Module 2ABU6-MS88SF2”
