IR-200M
The IR-200M is a handheld infrared wireless microphone. It eliminates problems with interference or eavesdropping, allowing for simultaneous use in adjacent conference rooms or school classrooms. The infrared wireless microphone system uses a frequency band that does not interfere with the TS-800 and TS-900 series infrared conference system, allowing both systems to be simultaneously installed in the same location.
(*1) Do not use battery together with rechargeable or dry batteries of different product numbers.
Failure to follow this instruction may result in battery leakage or excessive heat generation.
