Intertek Testing Services - Menlo Park Acer Advanced Labs. FHSS, FCC ID: Date of Test: May 24-28, 1999 3.3 Justification For emission testing, the equipment under test (EUT) was configured for testing in a typical fashion (as a customer would normally use it). During testing, all cables were manipulated to produce worst case emissions. For radiated emission measurements, the EUT is attached to a cardboard box (if necessary) and placed on the wooden turntable. If the EUT attaches to peripherals, they are connected and operational (as typical as possible). The EUT is wired to transmit full power. The signal is maximized through rotation and placement in the three orthogonal axes. The antenna height and polarization are varied during the search for maximum signal level. The antenna height is varied from 1 to 4 meters. Radiated emissions are taken at three meters unless the signal level is too low for measurement at that distance. If necessary, a pre-amplifier is used and/or the test is conducted at a closer distance. All readings are extrapolated back to the equivalent three meter reading using inverse scaling with distance. 3.4 Software Exercise Program The EUT exercise program used during radiated and conducted testing was designed to exercise the various system components in a manner similar to a typical use. 3.5 Mode of Operation During Test For radiated emission measurements, the EUT were setup to transmit continuously to simplify the measurement methodology. Care was taken to ensure proper power supply voltages during testing. 3.6 Modifications Required for Compliance The following modifications were installed during compliance testing in order to bring the product into compliance (Please note that this list does not include changes made specifically by Symbol Technologies Inc. prior to compliance testing): No modifications were made to the EUT by Intertek Testing Services.

FHSS, FCC ID: Date of Test: May 24-28, 1999 4.0 Measurement Results 4.1 Maximum Conducted Output Power at Antenna Terminals , FCC Ref: 15.247(b): With the hopping function turned OFF: [ ] The antenna port of the EUT was connected to the input of a power meter. Power was read directly and cable loss correction was added to the reading to obtain power at the EUT antenna terminals. [X] The antenna port of the EUT was connected to the input of a spectrum analyzer. The analyzer was set for maximun RES BW and power was read directly in dBm. For antennas with gains of 6 dBi or less , maximum allowed transmitter output is 1 watt (+30 dBm). For antennas with gains greater than 6 dBi, transmitter output level must be decreased by an amount equal to (GAIN - 6)/3 dBm.

FHSS, FCC ID: Date of Test: May 24-28, 1999 4.4 Minimum Number of Hopping Frequencies, FCC Ref: 15.247(a)(1)(i&ii) The RF passband of the EUT was divided into 4 approximately equal bands. With the analyzer set to MAX HOLD readings were taken for 2 - 3 minutes in each band. The channel peaks so recorded were added together,and the total number compared to the minimum number of channels required in the regulation. No. of hopping channels 79 Minimum Requirements: at least 50 channels for 902 - 928 MHz band; at least 75 channels for 2400 - 2483.5 and 5725 - 5850 MHz systems Refer to the plots 4.4a - 4.4d, which are attached as exhibits.

Intertek Testing Services - Menlo Park Acer Advanced Labs. FHSS, FCC ID: Date of Test: May 24-28, 1999 4.5 Average Channel Occupancy Time, FCC Ref: 15.247(a)(1)(i&ii) The spectrum analyzer center frequency was set to one of the known hopping channels. The SWEEP was set to 0.4 second, the SPAN was set to ZERO SPAN, and the TRIGGER was set to VIDEO. The time duration of the transmission so captured was measured with the MARKER DELTA function. The sweep was then set to the time required by the regulation (20 seconds for 902-928 MHz devices, 30 seconds for all other bands). The analyzer was set to SINGLE SWEEP, the total ON time was added and compared against the limit (0.4 seconds). The Average time is equal 75Η5=375 ms. Refer to the plots 4.5a - 4.5b, which are attached as exhibits, for details. LTO# J99009659 10
