From: Errol Chang echang@fcc.gov FCC Application Processing Branch Re: FCC ID K66VX-900V Applicant: Vertex Standard Co., Ltd. Correspondence Reference Number: 17884 731 Confirmation Number: EA99480 1. There is an abrupt discontinuity in the SAR distribution indicated on the plot for 161 MHZ body-worn SAR (the one with 3.3 W/kg). The is not normal and appears to indicate the output power has been disrupted during the SAR. Please verify a nd if necessary, repeat the SAR measurement. Addressed from Celtech 2. The dipole validation results submitted are for 835 MHZ, which is substantially different than the o perating frequency of this device (150 MHZ), please clarify and provide appropriate dipole validation results to confirm system measurement ac curacy and to ensure the E-field probe is properly calibration. In progress will come from Celtech directly with Kwok Chang / Measurement Uncertainty 3. The SAR results submitted for this filing indicates this device only meets occupational exposure lim it. It does not comply with general Page 1

FW Information requested.txt population exposure limit. In order for this device to qualify for occupational exposure limit, users must have the appropriate training so that they will have the knowledge to control their exposure conditions and duration to satisfy the higher oc cupational exposure limit. The submitted RF exposure info for the manual is insufficient. Please submit the specific training info fo r satisfying occupational exposure requirements. For training info to be placed in the manual, a caution/warning label should be placed o n the device, visible to the users, directing them to the specific training info in the manual. Please upload relevant pages of this train ing information. From Mikkio 4. Please provide a photo or clear illustration showing exactly where this RF exposure label will be lo cated on the device. (See #7 below) 5. The RF exposure info on the label should be in the form of a CAUTION statement, indicating that this device must be limited to occupational use and users must follow the training information specified in the manual for meeting FCC RF exposure compliance requirements. The RF exposure label can be a separate label but it should be visible to all persons op erating with this device. Please specify the font size and label size. (See #7 below) 6. The training information in the manual should include warning/cautions statements to alert users tha t this device is not approved for use by the general population as it only meets the higher exposure limit for occupational use, including an ap plicable duty factor. It should also clearly state that users are required to have appropriate training to control their exposure condition and duration to satisfy the higher occupational exposure limit before using this device. (See #7 below) 7. As an example of RF exposure label and training info requirements, please review a recently approved filing of a similar transmitter under FCC ID: OWDTR-0006-E, on how to revise the info required for this filing. Note: Output measured at 4.79 W ERP Proposed Grant Conditions - Output is ERP. This transmitter has been tested for SAR compliance in Pus h-to-Talk and body-worn operating configurations. Body-worn SAR compliance is limited to the specific belt-clip tested for this device. This device must be restricted to work related operations in an Occupational/Controlled RF exposure Environment. All qualified end-users of t his device must have the knowledge to control their exposure conditions and/or duration to comply with Occupational /Controlled SAR limit and requirements. A label, as described in this filing, must be displayed on the device to direct users to specific training informat ion for meeting Occupational Exposure Requirements and users must be provided with the training information. The highest reported SAR values are - Head: 0.98 W/kg; Body- worn: 3.3 W/kg, both tested at 100% duty factor The items indicated above must be submitted before processing can continue on the above referenced appl Page 2
