2. GENERAL DESCRIPTION

The IR-200M (hand-held type) and IR-300M (hands-free type) infrared wireless microphones are intended for speech applications and use unidirectional electret condenser microphone units featuring high sensitivity and clear sound.

3. FEATURES

• Employs the PLL synthesizer system, allowing up to 6 different frequencies to be set.
• Powered by 2 IR-200BT rechargeable NiMH batteries or 2 AA alkaline batteries.

Note

It is recommended that the microphone be used with the optional IR-200BT rechargeable battery that not only ensures longer microphone operation, but is also friendly to the environment.

• The IR-300M is equipped with an external microphone input terminal, allowing it to be used in combination with the YP-M101 tie-clip type microphone or YP-M301 headset microphone.
• The microphone system's infrared transmission eliminates problems with interference or eavesdropping, allowing simultaneous use in adjacent conference rooms or school classrooms.
• Since the infrared microphone uses a frequency band that does not interfere with that of the infrared conference system (TS-800 and TS-900 Series), both the infrared wireless microphone system and the conference system can be simultaneously installed in the same location.
  • Anti-bacteria-treated body.

4. HANDLING PRECAUTIONS

• Do not cover the infrared wireless microphone's infrared emitter with the hand or hide the microphone by placing it inside clothes. Covering the infrared emitter will disable light transmission.
• Avoid using the infrared microphone in close proximity to plasma displays or infrared LAN, which could lead to noise or microphone malfunctions.
• Do not dismantle or modify the infrared microphone.
  • Take care not to drop the infrared microphone on the floor or hit it on hard objects, as this could lead to microphone failures.
• The infrared microphone cannot be used outdoors or in areas exposed to direct sunlight.
• Do not place the infrared microphone in high-temperature locations, such as in a car parked with its doors closed in summer, or in highly humid locations, as this could lead to microphone failure.
• Avoid using the infrared microphone in locations that can be splashed with perspiration or seawater, as this could lead to microphone failures.
• When cleaning the infrared microphone, be sure to turn the power switch to OFF. Wipe with a soft dry cloth. If it gets very dirty, use the soft cloth slightly moistened in neutral cleanser. Never use volatile spirits like thinner, benzine, or alcohol. Such chemicals may damage its plastic surface.
