Regulatory Compliance Statements Federal Communications Commission (FCC) Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.  RF Exposure Information  This device meets the government’s requirements for exposure to radio waves. This  device  is  designed  and  manufactured  not  to  exceed  the  emission  limits  for exposure  to  radio  frequency  (RF)  energy  set  by  the  Federal  Communications Commission of the U.S. Government.  This device complies with FCC radiation exposure limits set forth for an uncontrolled environment.  FCC Radio Frequency Interference Statement   This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the distance between the equipment and the receiver. • Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help.  Changes or modifications not expressly approved by the party responsible for compliance could void the user‘s authority to operate the equipment.    Europe-European Union Notice Radio products with the CE alert marking comply with the R&TTE Directive (1999/5/EC) issued by the Commission of the European Community. Compliance with this directive implies conformity to the following European Norms (in brackets are the equivalent international standards).   • EN 60950-1 (IEC60950-1) - Product Safety • EN 300 328 Technical requirement for radio equipment • ETS 301 489 General EMC requirements for radio equipment. Products that contain the radio transmitter are labeled with CE alert marking and may also carry the CE logo.  Safety Use the following safety guidelines to help protect yourself and the PWS-430. • Do not attempt to service the PWS-430 yourself. Always follow installation instructions closely. • Be sure that nothing rests on the AC adapter's power cable and that the cable is not located where it can be tripped over or stepped on. • Do not cover the AC adapter with papers or other items that will reduce cooling; also, do not use the AC adapter while it is inside a carrying case. • Use only the AC adapter, power cord, and batteries that are approved for use with this PWS-430. Use of another type of battery or AC adapter may cause risk of fire or explosion. • If you use an extension cable with the AC adapter, ensure that the total ampere rating of the products plugged in to the extension cable does not exceed the ampere rating of the extension cable. • When you move the PWS-430 between environments with very different temperature
and/or humidity ranges, condensation may form on or within the PWS-430. To avoid damaging the PWS-430, allow sufficient time for the moisture to evaporate before using the PWS-430. • When you disconnect a cable, pull on its connector or on its strain relief loop, not on the cable itself. As you pull out the connector, keep it evenly aligned to avoid bending any connector pins. Also, before you connect a cable make sure both connectors are correctly oriented and aligned.  Battery Safety • There is a risk of explosion if the battery is replaced by an incorrect type. • Dispose of used batteries according to the instructions. • Do not dispose of batteries in a fire. They may explode. Check with local authorities for disposal instructions.  Notices This unit is equipped with a battery pack and backup battery. It is possible that the PWS-430 may not power-on due to battery discharge as a result of storage. In the above situation, insert the PWS-430 into the cradle and connect the AC adapter to the cradle. Recharge the unit for 3 hours in order to fully charge its battery. The backup battery will recharge from external power when the AC adapter is connected.  Battery charge notice It is important to consider the environment temperature whenever you are charging the Lithium-Ion battery pack. The process is most efficient at normal room temperature or slightly cooler. It is essential that you charge batteries within the stated range of 0°C to 50°C. Charging batteries outside of the specified range could damage the batteries and shorten their charging life cycle.  Storage and safety notice Although charged Lithium-Ion batteries may be left unused for several months, their capacity may be depleted due to build up of internal resistance. If this happens they will require recharging prior to use. Lithium-Ion batteries may be stored at temperatures between-20°C to 50°C, however they may be depleted more rapidly at the high end of this range. It is recommended to store batteries within normal room temperature ranges.   Table of Contents
