4. Storage Test Conditions
Parameter Min Max Unit
Storage Temperature -10 +80 ℃
Storage Humidity(40℃)-90 %
Caution : The specifications in Table 1 define levels at which permanent damage to the
device can occur. Function operation is not guaranteed under these conditions.
Operating at absolute maximum conditions for extend periods can adversely affect the
long-term reliability of the device.
Other conditions
1) Do not use or store modules in the corrosive atmosphere, especially where chloride
gas, sulfide gas, acid, alkali, salt or the like are contained.
Also, avoid exposure to moisture.
2) Store the modules is recommended where the temperature
and relative humidity 5 to 40℃and 20 to 60%.
3) Assemble the modules within 6 months.
Check the soldering ability in case of 6 months over.

(3) When starting RaUI, the system will connect to the AP with best signal
strength without setting a profile or matching a profile setting. It will issue
a scan command to a wireless NIC. After two seconds, the AP list will be
updated with the results of a BSS list scan.

User Information
The satisfy FCC exterior labeling requirements, the following test must be placed on the exterior of the end product.
Contains Transmitter module FCC ID: YZP-TWFML303D
This device complies with FCC radiation exposure limits set fo rth for an un controlled environment. This device should be installed and ope rated with minim um distance 20cm
between the radiating element of this device and the user. This device must not be co-located or operating in conjunction with any other antenna or transmitter.
This device is intended only for OEM integrators and following statements shall be included to host user manual
1) The antenna must be installed such that 20cm is maintained between the antenna and users.
2) This module may not be co-located with any other transmitters or antennas.
As long as 2 condition s above are me t, further tran smitter test w ill not be required. However, the OEM integrator is still res ponsible for testi ng their end-prod uct for a ny
additional compliance requirements with this module installed. In the event that these co nditions cannot be met, then the FCC a uthorizations are no longer considered valid and
the FCC ID cannot be u sed on the final produ ct. In these circu mstances, the OEM integrat or will be re sponsible for re-evalu ating the end produ ct including this mod ule and
obtaining separate FCC authorizations.
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 technical for help.
– 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 technical for help.
This device complies with Part 15 of the FCC`s 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 undesirable operation.
G Innotekdeclares that this TWFM-L303D-F is compliance with the essential requirements and other relevant provisions of directive 1999/5/EC.
This equipment may generate or use ra dio frequency energy. Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly
approved in the instruction manual. The user could lose the authority to operate this equipment if an unauthorized change or modification is made.
