AWMT 1. SAFETY To prevent the risk of personal injury or loss related to equipment malfunction ADVANTECH AMT™ uses the following symbols for safety related information. For your own safety, please read the information carefully BEFORE operating the equipment. Symbols used in manual: WARNING! This indicates a hazardous procedure that could result in serious injury or death if not performed properly. - Page 8 The permissible levels of exposure are quite low compared to the power levels of the transceivers built by ADVANTECH AMT™ (e.g. less than 10 mW versus 20 to 500 W delivered by various units). The permissible levels are currently being studied by a number of organisations.

Page 11: General Information
3. GENERAL INFORMATION This manual contains information that describes the installation, operation and maintenance procedures for the hub-mount (outdoors) Solid State Transceiver, model AWMT. Because specialized training is required for some phases of installation and operation, this manual is directed only to trained personnel. Warnings appear at the appropriate points to caution all users of potential RF and high-voltage hazards. -
Page 12: Major Subsystems And Their Functions
This Section describes how the hub-mount (outdoors) solid state transceiver functions. 4.2 DESCRIPTION The AWMT is an outdoor unit intended for mounting near the hub of an antenna (see Figure 1 at page 12 and Figure 2 at page 13). The unit incorporates a weather resistant enclosure that houses several electronic modules and a cooling system that protects the electronic components from overheating. -
