WarrantyFor the complete Symbol hardware product warranty statement, go to:http://www.symbol.com/warranty. Battery InformationSymbol rechargeable battery packs are designed and constructed to the highest standards within the industry.However, there are limitations to how long a battery can operate or be stored before needing replacement. Many factors affect the actual life cycle of a battery pack, such as heat, cold, harsh environmental conditions and severe drops.When batteries are stored over six (6) months, some irreversible deterioration in overall battery quality may occur. Store batteries discharged in a dry, cool place, removed from the equipment to prevent loss of capacity, rusting of metallic parts and electrolyte leakage. When storing batteries for one year or longer, they should be charged and discharged at least once a year. If an electrolyte leakage is observed, avoid any contact with affected area and properly dispose of the battery. Replace the battery when a significant loss of run time is detected.Standard warranty period for all Symbol batteries is 30 days, regardless if the battery was purchased separately or included as part of the mobile computer or bar code scanner. For more information on Symbol batteries, please visit:http:/mysymbolcare.symbol.com/battery/batbasics1.html.Battery Charging NoteTo charge the battery for the mobile device, battery and charger temperatures must be between +32° F and +104° F (0° C and +40° C).Ta i w a nEPA (Environmental Protection Administration) requires dry battery producing or importing firms in accordance with Article 15 of the Waste Disposal Act are required to indicate the recycling marks on the batteries used in sales, giveaway or promotion. Contact a qualified Taiwanese recycler for proper battery disposal.

Below is the photo comparison between old and new antenna. Old antenna mean the antenna used on 10/14/2005 origin filing New antenna mean the antenna used on 10/28/2005 revise test reports for superseding 10/14/2005 submitted test reports. A better in-band power performance has been achieved by length tuning as show below and accordingly the conducted power and radiated spurious emissions have been re-measured to demonstrate the continue compliance to the related rule parts.

Nov. 26, 2005 Applicant: Symbol Technologies Inc FCC ID# H9PMC7090 Correspondence Reference Number: 30003 731 Confirmation Number: EA140628 Date of Original E-mail: 11/22/2005 The responses are as follows: 1) fyi FCC weblink in user manual is wrong: (http://www.fcc.gove/oet/fccid), should be (http://www.fcc.gov/oet/fccid) or (https://gullfoss2.fcc.gov/prod/oet/cf/eas/reports/GenericSearch.cfm) 2) Filing (op desc, user manual, SAR, etc) indicates this handheld-terminal contains Bluetooth (BT) transmitter, but this does not seem to be listed on Form731 application. Typically BT are filed as eqpt class DSS, but can file under DTS. 2a) what is BT FCC ID (module?), or will handheld-terminal always be marketed containing BT such that present FCC ID can include it? 2b) if BT will always be installed and separate (module) FCC ID is not applicable, please submit exhibits into DTS application, or submit separate DSS composite application, to make complete filing for BT device 2c) if separate BT FCC ID will be retained, please submit device FCC ID labeling info for handheld-terminal in this filing 3) This filing has requested confidentiality for device photos; however, the SAR exhibits containing device photos cannot be held confidential. Please submit new exhibits with device photos and SAR report portions in separate files. 4) Some SAR report photos, and DUT-geometry in all SAR data plots, appears to show handheld-terminal with external stub antenna (assumed to be H9PMC7094), whereas this filing is for device does not have stub antenna. please explain, or revise/re-test if data in this filing is for device with stub-antenna. 5) Please list collocated SAR evaluation procedures, including info about grid/distribution additions, and device re-positioning (registration) when device is taken in and out of holder to activate the various transmitters. Response: 1) Thanks and we have revised the user manual. 2) The BT transmitter will be marketed with handheld-terminal always and no separate ID is required. Also, BT test report already included in the submitted 15.247 EMC test report. 3) Thanks for your suggestion and we have removed the test setup photos from the whole reports, and have it relocated to the test setup photo. Please refer to revised EMC test setup photos “TSup_H9PMC7090_rev.pdf “, “Test Rpt- SAR_H9PMC7094_rev2.pdf”“Test Rpt-SAR (Appendix A)_ H9PMC7090_rev3.pdf “,” 1 Test Rpt (15.247)_H9PMC7090_rev2.pdf”and” Test Rpt (15.407)_H9PMC7090_rev2.pdf”. 4) Since H9PMC7090 and H9PMC7094 are identical in shape and dimension except that H9PMC7094 has a extra stub antenna for part 22./ 24 function. So we had reused the DUT-geometry print from H9PMC7094 to the H9PMC7090 without re-editing the file to remove stub-antenna portion. We apologize for the minor error in the data presentation, and all the test data / plots submitted do represent the correct sample and operation. We will fix similar error in future application, thanks. 5) Collocated SAR evaluation procedure: Basically we use the post-procession function offered by DASY4 SAR system to perform the co-located SAR evaluation. The procedure is as follow: 1. Each mode is evaluated individually according to its maximum operating power and typical operating condition for all possible operation configurations and the worth- case-configuration from each mode was noticed and recorded for the following step. 2. Once all modes have been evaluated and individual worst case configuration & value are identified from each mode, the SAMCAD could be use to calculate the worst case collocated SAR by combine the related SAR values from related worst case measurement results. For detail procedure regarding to step 1 & 2 mentioned above and re-position procedure, please refer to following two files: a. Single transmitter SAR evaluation procedures.pdf b. Collocated SAR evaluation procedure.pdf Best regards, ADT 2

Chapter 30 Multiband Evaluation 30.1 Introduction Wireless devices exist that can transmit at multiple frequencies at the same time. An example of this is a cellular telephone and PDA combination that can simultaneously transmit a cellular telephone signal (e.g., at 900 MHz) and a wireless LAN signal (e.g., at 2450 MHz). It is possible that such a device may be compliant with the regulatory SAR limit at each frequency while the composite SAR from simultaneous transmission is above the limit. Therefore, the accurate determination of the SAR in this situation is important. Given that the tissue simulating liquid and the probe calibration are frequency dependent, and given that existing SAR measurement systems are unable to separate the frequency components of a signal, it is not possible to accurately measure the SAR from such a transmitter using one measurement in one liquid. DASY4 therefore provides the possibility to perform such Multiband Evaluations according to the latest standards, e.g., [1] using the Volume Scan job as well as appropriate routines for the Postprocessing. 30.2 Multiband Measurements The Volume Scan job described in Section 7.2.11 Volume Scan job allows to conduct the mea­ surement of volumes with sufficient spatial extend such as outlined in the procedure proposed in [1]. The resulting measurement jobs can be finally evaluated and combined within the SEMCAD Postprocessor. 30.3 Multiband Data Extractions In order to extract and process measurements within different frequency bands, the SEMCAD Postprocessor allows to combine and subsequently superpose these measurement data in the Chart Manager. 30­1 Multiband Evaluation Application Notes The appropriate process is outlined as follows: 1. Via drag­and­drop, the quantities to be combined can be added to the Chart Manager. Note: Since different media were used at measuring the various bands, the re­ sults from the different Programs need to be added to one single Chart Manager. Therefore, the user can open two (or more) instances of SEMCAD, and drag­drop a specific result from one SEMCAD instance to the Chart Manager of another one. Note: The measurement grids of the jobs which should be combined in the Post­ processor should be the same, i.e., should contain the same number of points located approximately at the same locations. 2. Via multiple selection within the Chart Manager list, the appropriate items to be combined can be chosen. By use of the Shift or Ctrl keys on the keyboard in addition to mouse clicking in oder an appropriate set of items is selected. Application of the Multiband extrac­ tion to a set of items in the Chart Manager. Note: In order to evaluate and combine Averaged SAR, the Custom Averaged SAR result field should be selected. 3. In a next step, the kind of viewer to be used for the visualization or the data export, can be selected. Selection of a viewer type in the Ex­ traction Options dialogue. 4. In a final step, the results are displayed graphically and by numbers in the selected viewer or are exported as defined by the user.

Note: For the Volume Scan job, in addition to the common quantities, SEMCAD allows the extraction of the Total Absorbed Power in the medium. This will be extracted for the Averaged and Interpolated SAR result fields. Note: In order to perform a printout of the combined measurement data, please use the MulitbandPrintout.htm print template provided in the appropriate folder on the DASY4 CD.

GENERAL DESCRIPTION OF THE SPATIAL PEAK SAR EVALUATION The DASY4 post-processing software (SEMCAD) automatically executes the following procedures to calculate the field units from the micro-volt readings at the probe connector. The parameters used in the evaluation are stored in the configuration modules of the software: Probe parameters: -Sensitivity Norm i , a i0 , a i1 , a i2 -Conversion factor ConvF i -Diode compression point dcp i Device parameters: -Frequency F -Crest factor cf Media parameters: -Conductivity -Density The first step of the evaluation is a linearization of the filtered input signal to account for the compression characteristics of the detector diode. The compensation depends on the input signal, the diode type and the DC-transmission factor from the diode to the evaluation electronics. If the exciting field is pulsed, the crest factor of the signal must be known to correctly compensate for peak power. The formula for each channel can be given as: i =compensated signal of channel i (i = x, y, z) i =input signal of channel I (i = x, y, z) cf =crest factor of exciting field (DASY parameter) dcp=diode compression point (DASY parameter) i From the compensated input signals the primary field data for each channel can be evaluated: The …
