This device emits Radio Frequency (RF) energy. Extreme caution should beobserved when operating this device. If you have any ques-tions regarding RF exposure and safety standards pleaserefer to the Federal Communications Commission Office ofEngineering and Technology ’ s report on Evaluating Compliance with FCC Guidelines for Human Radio frequencyElectromagnetic Fields (OET Bulletin 65) WARNING! NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of thebody, especially the face or eyes, while transmitting. Thetransceiver will perform best if the microphone is 1 to 2 in (2to 5 cm) away from the lips and the transceiver is vertical. WARNING! NEVER operate the transceiver with a headset or other audio accessories at high volume levels.Hearing experts advise against continuous high volume oper-ation. If you experience a ringing in your ears, reduce the vol-ume level or discontinue use. NEVER CONNECT a power supply more than 11.5 V DC to the DC jack. The supply voltage must be between 5.5 V and 11.5 V to prevent damaging the trans- ceiver. NEVER connect the transceiver to an AC outlet . Such a connection will damage the transceiver. NEVER connect the transceiver to a power source that is DC fused at more than 5 A. Accidental reverse connection willbe protected by this fuse, but higher fuse values will not giveproper protection against such accidents and the transceiverwill be ruined. DO NOT operate the transceiver near unshielded electrical blasting caps or in an explosive atmosphere. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below +14 ° F ( – 10 ° C) or above +140 ° F (+60 ° C). The use of non-Icom battery packs/chargers may impairtransceiver performance and invalidate the warranty.Even when the transceiver power is OFF, a slight current stillfl ows in the circuits. Remove the battery pack or case from the transceiver when not using it for a long time. Otherwise,the battery pack or installed batteries will become exhausted.For U.S.A. only CAUTION: Changes or modi fi cations to this device, not ex- pressly approved by Icom Inc., could void your authority tooperate this device under FCC regulations.

The preliminary test was carried out to investigate the frequency of the emission that has the highest amplitude relative to the limits within normal operating modes, cable positions, and a typical system configuration. In order to find out to the maximum emission, the preliminary test and a final test were performed in accordance with the following steps. Step 1: One operation mode of the test system was setting. Step 2: Using a test receiver and a test antenna probe, the significant frequency of the emission's circumstance from the test system were investigated. These data were recorded every one of 22 divided bands in the specified frequency band (30 MHz - 1000 MHz). Step 3: Using a test receiver and a linearly polarized broadband antenna, the emission's circumstance from the test system was measured in according with ANSI C63.4-1992 Sec.8.3.1.2 (Final Radiated Emissions Tests) at each frequency which was found the higher emission referred to level vs. frequency on the list and which was measured by the resonant tuned dipole antenna. The maximum emission was found by changing the cable positions or cable manipulation under a typical system configuration. Step 4: Return to step 1, if the other operation mode was possible to be setting. Step 5: The worst result was reported arranging data of which was obtained and performed by one or plural operation modes as the final test. At the worst point that has the highest amplitude relative to the limit the repeatability of the level was reconfirmed. The photographs of the tests system setup on the worst point were taken and recorded. ò-3m ô-10m EUT1-4 mTest Receiver 0.8 m Ground Plane Turntable30 MHz - 300 MHz : Biconical Antenna 300 MHz - 1000 MHz : Log-periodic Antenna JQA Application No. : KL80020142Regulation : CFR 47 FCC Rules Part 15 Model No.: IC-T90AIssue Date : July 5, 2002 FCC ID: AFJ IC-T90A Page 18 of 85 Electromagnetic Field Radiated Emission 1 GHz - 2.2 GHz: The preliminary test was performed according to the description of ANSI C63.4-1992 Sec.8.3.1.1 (Preliminary Radiated Emissions Tests) and Sec.6.2.1 (Tabletop Equipment Tests). The preliminary test was carried out to investigate the frequency of the emission that has the highest amplitude relative to the limits within normal operating modes, cable positions, and a typical system configuration. In order to find out to the maximum emission, the preliminary test and a final test were performed in accordance with the following steps. Step 1: One operation mode of the test system was setting. Step 2: In order to investigate the frequencies of maximum emissions, the horn antenna position was approached to the EUT and the significant frequency of the emission's circumstance from the test system were investigated. These data were recorded in the specified frequency band (1 GHz - 2.2 GHz). Step 3: The emission's circumstance from the test system was measured in accordance with ANSI C63.4-1992, Sec.8.3.1.2 (Final Radiated Emissions Tests) at each frequency which was found higher emission referred to level vs. frequency on the list and which was measured in the specified distance using the horn antenna.
