Page 3: Safety Precautions
1. SAFETY PRECAUTIONS These precautions apply only to the IR-702T Infrared Wireless Tuner. For precautions regarding other infrared microphone system devices, please refer to the instruction manual included with each device. • Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation. -
Page 4: General Description
• Up to 16 infrared wireless receivers can be installed with the use of the IR-700D Infrared Wireless Distributor. • Since the IR-702T tuner 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. -
