1. An exhibit has been uploaded with the radiated emissions test data showing the signal substitution factor
and also a test setup photo.

2. The emission designator need to be changed to 12M1K1D. Which is 12 MHZ
bandwidth,Modulation AM (Manchester encoded ON/Off Keying),frequency band
902-928 (K),data (D). The modulation scheme used is Manchester Encoded
ON/OFF Keying. This is single frequency operation unit (915.75 MHZ).The data
frequency is 500 KHZ. The unit meets the sidebands requirements in the
bandwidth of 909.75-921.75 MHZ as per part 90. So THE Bandwidth required is
12 MHZ.There are two modes of operation as described in the design
description,

3. The user manual shows the box,antenna,power supply and software.The box
contains the current production RF Module FCC ID: JQU-800495 which is also used in
the Road Check Reader system in the toll collection,digital board and
attenuators. This new FCC ID: JQU-801154 will replace the JQU-800495 RF module in
the Mgate reader application. This new unit was designed to reduce the
system cost. For the ease of test and qualification this unit can be tested
with our current reader. So the user manual will be modified to have the new
unit replacing the old unit. The old RF Module (JQU-800495) is an enclosed
unit with covers on both sides and rf connectors at the side of the
housing.This unit has shields for the sensitive parts of the circuit.

4.The user manual will be modified to include the statement about the RF
exposure " This device shall cause no harm at a distance greater than 1
meter away from the antenna". The CR2000 Reader Installation instructions
shows that the antenna is mounted 12 feet high above the ground so the RF
exposure is minimal.
