Notes on use
• Two transmitters on the same frequency cannot be used simultaneously.
• Please be aware that interference may be generated from the surrounding electromagnetic environment and/or from
using multiple units.
• The wireless system may be affected by electromagnetic noise from automobile spark plugs, light dimmers, computers,
OA devices, or electrical music instruments. Position the components of the system in a place where it is less likely to be
affected.
• Only use this product in combination with devices specified by the manufacturer.
• Insert the plugs of connecting cables securely into their mating connectors.
• Radio waves in the UHF band propagate mainly by line of sight. Configure system so there are no obstructions between
the transmitter and receiver.
• Do not use outside the USA. Use abroad may be punished according to the laws of the relevant country.
• Unplug the product when unused for long periods of time.
• Use 120 V AC power source. Refer to "Specifications" for product ratings.
Using multiple wireless systems
• When using multiple units simultaneously, maintain approximately 1 meter or more between individual transmitters and
approximately 10 meters or more between transmitters and receivers.
•
When using multiple units, power on transmitters one by one, making sure there is no unwanted noise.
Maintenance
• When you unplug the power cable, if the plug is dusty or dirty, wipe it off with a soft, dry cloth.
