Rhein Tech Laboratories, Inc. Client: Alinco, Inc. 360 Herndon Parkway Model: DR-635T Suite 1400 Standards: FCC 15.121 Herndon, VA 20170 & IC RSS-215 http://www.rheintech.com Report #: 2005040 APPENDIX C: ATTESTATION LETTER Please refer to the following page. Page 16 of 37

20 Jan, 2005 Federal CommunicationsCommissions RE: PHB DR-635T/ 800MHz analogcellular telephoneband blocking Dear Sir or Madam, This is to declarethat the devicein applicationPHB DR-635Thas beenblockedfor any and all accessof 824.00to 849.9975MH2and 869.00to 894.9975MH2. The deviceuses double super heterodyne PLL synthesizer circuitry as a receiver circuit and its first oscillation frequencyis determinedby a [nl figure generatedin CPU. The first local oscillation frequenciesdetermined by the [nl figures are as follows: FM broadcastingband: 98.2- 118.7MH2 AM aviation band: 129.7- L57.7MHz vHF band: rt4.3 - r52.3MHz UHF LOW band:(+OO- 420MHd ++S.r- 465.1MH2 UHF HIGH band: @20- 480MHz) 374.9- 4:34.9MH2 vHF-side 360MHzband: 356j - 42r.7MHz UHF'side 360MHzband:380.1- 445.1MH2 suB-bandvHF: 181.1- 2r9.1MHz suB-band UHF: 378.3- 458.3MH2 In addition, the harmonics are filtered out with Low-passfilter circuit before the signal goesinto the mixer circuit, therefore800MHz range can't be received.Theseoscillation frequenciescan't be altered.Also the Radio Frequencycircuits for abovedeclaredbands are all composedof Low-passfilters and synthesizer.The CPU used in this device,our parts code XA1082, vender's code M30624FGPGPis exclusively programmed and burned for US export model.Alinco, Inc exports solely this version to the US market, and this CPU can't be modified by any means to receive the cellular frequencies declaredabove. Respectfutly, Kazuhiro Kusuhara General manager, Production Section, Alinco, Inc. Electronics Division
