FCC ID: K6610583020 IC ID: 511B-10583020 Operating Manual 1/7 Vertex Standard Co., Ltd. VX-820/870 series Operating Manual SAFETY TRANING INFORMATION This Radio has been tested and complies with the Federal Communications Commission (FCC) RF exposure limits for Occupational Use/Controlled exposure environment. In addition, it complies with the following Standards and Guidelines: - FCC　96-326, Guidelines for Evaluating the Environmental Effects of Radio-Frequency Radiation. - FCC OET Bulletin 65 Edition 97-01 (1997) Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. - ANSI/IEEE C95.1-1992, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3kHz to 300 GHz. - ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields-RF and Microwave. WARNING: This radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as Occupational Use Only, meaning it must be used only during the course of employment by individuals aware of the hazards, and the ways to minimize such hazards. This radio is not intended for use by the General Population in an uncontrolled environment. CAUTION: To ensure that your expose to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines: - This radio is NOT approved for use by the general population in an uncontrolled environment. This radio is restricted to occupational use, work related operations only where the radio operator must have the knowledge to control its RF exposure conditions. - When transmitting, hold the radio in a vertical position with its microphone 1 to 2 inches (2.5 to 5 cm) away from your mouth and keep the antenna at least 1 inch (2.5cm) away from your head and body. - The radio must be used with a maximum operating duty cycle not exceeding 50 %, in typical Push-to-Talk (PTT) configurations. DO NOT transmit for more than 50 % of total radio use time (50 % duty cycle). Transmitting more than 50 % of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio is transmitting when the red LED on the top of the radio is illuminated. You can

1 ©2009 VERTEX STANDARD CO., LTD. EC058U90D UHF Band Service Manual VX-820/-820E Series Introduction This manual provides the technical information necessary for servicing the VX-820 Series Transceiver. Servicing this equipment requires expertise in handing surface-mount chip com- ponents. Attempts by non-qualified persons to service this equipment may re- sult in permanent damage not covered by the warranty, and may be illegal in some countries. Two PCB layout diagrams are provided for each double-sided board in this transceiver. Each side of the board is referred to by the type of the majority of components installed on that side (“Side A” or “Side B”). In most cases one side has only chip components (surface-mount devices), and the other has either a mixture of both chip and leaded components (trimmers, coils, electrolytic ca- pacitors, ICs, etc.), or leaded components only. As described in the pages to follow, the advanced microprocessor design of the VX-820 Series Transceiver allows a complete alignment of this transceiver to be performed without opening the case of the radio; all adjustments can be per- formed from the front panel, using the “Alignment Mode” menu. While we believe the information in this manual to be correct, VERTEX STAN- DARD assumes no liability for damage that may occur as a result of typographi- cal or other errors that may be present. Your cooperation in pointing out any inconsistencies in the technical information would be appreciated. Important Note After Lot. 11 of this transceiver was assembled using Pb (lead) free solder, based on the RoHS specification. Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this apparatus. The solder stated above utilizes the alloy composition required for compliance with the lead-free specification, and any solder with the above alloy composition may be used.
