A Installing the battery (See fig. A) 1 Open the battery compartment lid. 2 Place the CR2025 battery (not supplied) with the + side facing upward. Be sure to place the battery with polarity positioned correctly. Battery life The Sony CR2025 lithium battery (not supplied) gives continuous operation on the microphone for about 350 hours. When you turn the power on, the battery check indicator lights momentarily. When the battery becomes weak, the indicator lights dimly or does not light at all. In this case, replace the battery with a new one. (Sony CR2025 lithium battery (not supplied)). To avoid battery wear or leakage, be sure to turn the power off after using the microphone. When the battery compartment lid comes off 1 Hold down part A with a thumb so that it does not slide. 2 Insert one of the parts of A into the projecting part B of the battery compartment and then insert the other part while pressing toward the inside. Removing the battery (See fig. B) When to replace the battery When the power is turned on, the battery check indicator lights momentarily. When the battery become weak, the indicator remains dimly lit or does not light at all. In this case, replace the battery with Sony CR2025 lithium battery. Use of another battery may present a risk of fire or explosion. Under normal conditions of use, the battery will last approximately 350 hours. Notes on lithium battery • Keep the lithium battery out of the reach of children. Should the battery be swallowed, immediately consult a doctor. • Wipe the battery with a dry cloth to assure good contact. • Be sure to observe the correct polarity when installing the battery. • Do not hold the battery with metallic tweezers. Doing so can cause a short-circuit. WARNING Battery may explode if mistreated. Do not recharge, disassemble or dispose of in fire. 1 2 B 1 2 + side pôle + lado + – side pôle – lado – Lithium battery CR2025 (not supplied) Pile au lithium CR2025 (non fournie) Pila de litio CR2025 (no suministrada) A B Parts Identification and Uses (See fig. D) 1 Directive angle switch Set the switch according to the sound source. 90˚: Use to pick up a relatively narrower sound source (instrumental solo, conversation, etc.), to provide a clear stereo sound image focused on target source. 120˚: Use to pick up a relatively wider sound source (orchestra, chorus, stage play, etc.), to provide a natural stereo sound image with full reality. The above are guidelines for selecting an appropriate angle. Although following these guidelines is encouraged, you can freely select either angle according to your own preference. Note If you switch the angle during recording, noise may occure. 2 Gold-plated triple-pole stereo miniplug Connect to the MIC jack of your recording equipment (video camera, etc.) 3 Battery compartment lid 4 Power switch ON: Select when the microphone works with the battery. OFF: Select when the microphone works with plug-in power or when you turn it off. When you use a Sony video camera with plug-in power system, set the power switch to OFF. 5 Battery check indicator When the power is turned on, this indicator lights momentarily. When the battery becomes weak, the indicator remains dimly lit or does not light at all. In this case, replace the battery with a new one.
