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.
