OPERATING INSTRUCTIONS
RM-500 Thank you for purchasing TOA’s Remote Microphone.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.

SAFETY PRECAUTIONS

Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation.
Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or cautions regarding safety.
After reading, keep this manual handy for future reference.

WARNING Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.
CAUTION Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

WARNING
When Installing the Unit

Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.
Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.
Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down and causing personal injury and/or property damage.
Since the unit is designed for indoor use, do not install it outdoors. If installed outdoors, the aging of parts causes the unit to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a danger of electric shock.

When the Unit is in Use

To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to qualified service personnel.
Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.
Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the unit’s bottom surface, as this may result in fire or electric shock.

CAUTION
When Installing the Unit

Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.
Use the dedicated AC adapter for the unit. Note that the use of other adapter may cause a fire.

GENERAL DESCRIPTION

The RM-500 is a desktop type remote microphone for general broadcasts designed to be connected to the VX-3000 Series Integrated Voice Evacuation System.

FEATURES
