5. SUMMARY
5-1 Test Results
This lesl reporl clearly shows that Ihe EUT complies with lhe FCC Part 153 Class B specificalion
The minimum marg'ns lo lhe limits are as follows:
— Conducted measuremenl 8.7 dB al 1.9496 MHz (Mode 2)
— Radialion measuremenl 4.2 dB al 30.000 MHZ (Mode 5)
This data rcpresenl the worst case emissions.
5-2 Sample Calculations
5-2-1 Conducted Emission
Example 1.9496 MHZ
Emission Level = Meler Reading 38.7 dBnV
+ *LlSN Factor + 0.6 dB
: 39.3 dBuV
Margin = Limil 480 dBuV
- Emission Level — 39.3 dBuV
: 8.7 dB
“ The above LlSN factor includes cable loss.
The numerical value are rounded off (0 one decimal place.
5-2-2 Radiated Emlssion
(frequency range : 30 MHZ — [000 MHZ)
Example 30.000 MHz
Emission bevel : Meter Reading 37.0 dBuV
+ Antenna Faclor + 19.3 dB
+ Cable Loss (*) - 20.5 dB
= 35.8 dBuV/m
Margin = Limil 40.0 dBuV/m
- Emission Level - 35,8 dBuV/m
: 4.2 dB
Me|er reading : Test Receiver reading
(‘)The above Cable Less means that add Anlenna Pad Loss to Cable boss and sublracr Amplifier Gain
The numerical values are rounded off to one decimal place.

Bibliography
Since commencing operation in 1942 as a watch manufacturer, Seiko Epson
Corporation has utilized its own original micromeehatronics technologies, gained while
developing quartz watches, to diversify into a variety of fields, as camputcrs, printers
and electronic devices, including semiconductors and liquid crystal displays. The phase
“highly functional and highly compact" best describes the policy of our product
development activities
Since the initial electrical printer was manufactured in 1971, Seiko Epson
Corporation has been working for EMC field. It is a combination of precise machine
technology and electric technology
Now EMC group has 3 semi-aneehoic chambers and 8 EMl/EMC test facilities
and full responsibilities on EMC lesting. It is independent from any other business
organizations and admired by the president as neutral and it’s independently,
