KHK88001205Low Power Remote Temperature Transmitter

Please ignore the original label location, because the manufacturer stuck the FCC ID label to receiver. Now they have revised it. The revised label location downloaded to web site. Besides,the internal photos are correct. Amendment report downloaded to web site.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 January 2, 2006 RE: Wai Hang Electronic Co., Ltd. FCC ID: KHK88001205 I have a few comments on this Application. Depending on your responses, kindly understand there may be additional comments. 1.) Kindly supply an exact label artwork drawing for this device as it shall be labeled for sale. 2.) FYI: There is an incorrect interpretation of the permissible limits for spurious emissions for this device. Whenever the Restricted Band emission limits are higher than the limits as applied in any specific Intentional Radiator section, the stricter limits will apply. For this case, all spurious emissions must meet the 52.8dBuV average limit, and not the limits shown in 15.205. This does not appear to change the pass/fail radiated emissions criteria, but should be changed for clarity. . William H.

The difference can be seen after de-modulation. Hence no analog variation can be observed in Spectrum Analyzer. The EUT is used in ASK not FSK, sorry for mistake. The waveform of ASK/FSK signal like, the series code of TX & Rx changed, the channel may change, 2ASK , below is carrier 2FSK Hope this can help you.

So changing the 'channel' will not affect the frequency. But what about radiated field strength? Will it affect other parameters? What about 20db BW? What about any of the pulse timing or repetition parameters? In other words, what would I see different on a spectrum analyzer if I saw the 'channels' changed? Bill From: Chen, Jerry (Guangzhou) [mailto:[email protected]] Sent: Wednesday, January 11, 2006 2:53 PM To: [email protected] Cc: Li, Cherry (Guangzhou); Wu, Gavin (Guangzhou) Subject: RE: KHK88001205 Dear Graff, Thanks for your hard work. The Tx only used 433.92MHz as carrier for all channels, and by changing the modulation method (FSK) to make different channels. Hence we performed test on one of channels.

Please observe the newest Label uploaded 01/10/2005 and on file at our website. The EUT appears to suggest that any one of three 'channels' can be selected. But all of the reports and manual given suggest that this is only a single-channel 433.79MHz transmitter. If there are extra frequencies that this can be set, then these must be tested too! I know this is an urgent filing, and I would only ask if this was important. Please look as soon as possible and tell me what is going on.

I will check the case’s reviewer in your web site next time. Sorry to trouble you and Douglas. By the way, due to we hadn’t emphasized our client to add Pt.15.21 statement in manual. Hence I will remind our client to add it from now on. The revised manual would be downloaded to web site soon. I was thankfull that you and Bill gave me great support once again.

You may check the case’s reviewer from our web site. 1/12/2006 I have asked Bill to expedite this case. Hopefully we can issue you the Grant by this afternoon. But, there is still a little problem in the manual. As I explained to you the other day, the manufacturer has to put Part 15.21 statement in manual. As I double check with this one, there is nothing in it. As Bill understands that your customer is very urgent to get Grant, he agrees to issue the Grant first. But, you have to ask your customer addin g the statement in the manual (I found there is still space in the last page of the manual) and upload the revised manual to our web site within 5 days. Otherwise, the Grant may possibly be dismissed 5 days later. Call me if you have any question.
