SECTION SERVICING NOTES UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

HOW TO CHANGED THE CERAMIC FILTERS This model is used two ceramic filters of CF and CF3. You must used same type of color marked ceramic filters in order to meet same specifications. Therefore, the ceramic filter must be changed two pieces together since it s supply two pieces in one package as a spare parts. mark CF3 CF Mark red blue orange black white Center frequency 0.70 MHz 0.67 MHz 0.73 MHz 0.64 MHz 0.76 MHz B Insert the E side of the battery first. Inserte primero el lado E de la pila. MW SW Installing the batteries (See fig. A) Open the battery compartment lid. 2 Install two R20 (size D) batteries (not supplied) with correct polarity. 3 Close the lid. Battery life (Approx. hours) (JEITA*) When using SW MW Sony R20 (size D) 200 220 220 * Measured by JEITA (Japan Electronics and Information Technology Industries Association) Standards. The actual battery life may vary depending on the circumstance of the unit. When to replace the batteries When the sound becomes weak or distorted, replace all the batteries with new ones. Notes on batteries Do not charge the dry batteries. Do not carry the dry batteries with coins or other metallic objects. It can generate heat if the positive and negative terminals of the batteries are accidentally contacted by a metallic object. Do not use different types of batteries at the same time. When you replace the batteries, replace all with new ones. When you are not going to use the unit for a long time, remove the batteries to avoid damage from battery leakage and corrosion. Improving the reception (See fig. B) : Extend the telescopic antenna and adjust the angle for optimum reception. MW: Rotate the unit horizontally for optimum reception. A ferrite bar antenna is built into the unit. SW: Extend the telescopic antenna vertically. Note Adjust the direction of the antenna by holding the bottom of it. The antenna can be damaged when you move the antenna with excessive force. 2
