Dear Helen,

Question #1: Please resubmit a clearer schematic diagram.
---> Attached please find Schematic.pdf!

Question #2: The operational description indicates: "The module will be transmitting when the
RF module data input is Hi; the module will stop transmitting when the
RF module data input is Low". The test report indicates: "This EUT works as a FM modulation.
Signal HI will trigger FM OSC to generate a 915.004MHz frequency and signal LOW will trigger FM
OSC to generate a 914.996MHz frequency. It is only 0.008MHz deviation, so that there is no duty
cycle on it." Please confirm whether the RF module data input Hi" equals signal HI stated in
the report; the RF module data input Low equals signal LOW stated in the report. If the answer
is yes, please clarify whether the device is still transmitting RF signal when the signal is
low. The test report contradicts the operational description on this. You may need to update
the relevant document.
---> Attached please find Operation description.pdf!

Best Regards,
Joy Hsiao
