General notes Signal word Meaning DANGER! This combination of symbol and signal word indicates an immediate dangerous situation that will result in death or serious injury if it is not avoided. CAUTION! This combination of symbol and signal word indicates a pos‐ sible dangerous situation that can result in minor injury if it is not avoided.
Safety instructions 2 Safety instructions Intended use This device is intended to be used in a sound reinforcement system. Use the device only as described in this user manual. Any other use or use under other operating conditions is consid‐ ered to be improper and may result in personal injury or property damage. No liability will be assumed for damages resulting from improper use.
Safety instructions DANGER! Electric shock caused by high voltages inside Within the device there are areas where high voltages may be present. Never remove any covers. There are no user-serviceable parts inside. DANGER! Electric shock caused by short-circuit Always use proper ready-made insulated mains cabling (power cord) with a pro‐ tective contact plug. Do not modify the mains cable or the plug. Failure to do so could result in electric shock/death or fire.
Safety instructions CAUTION! Possible hearing damage The device can produce volume levels that may cause temporary or permanent hearing impairment. Over an extended period of time, even levels that seem to be uncritical can cause hearing damage. Decrease the volume level immediately if you experience ringing in your ears or hearing impairment. If this is not possible, keep a greater distance or use suffi‐ cient ear protectors.
Safety instructions NOTICE! Risk of fire Do not cover the device nor any ventilation slots. Do not place the device near any direct heat source. Keep the device away from naked flames. NOTICE! Operating conditions This device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and strong vibrations.
Safety instructions NOTICE! Power supply Before connecting the device, ensure that the input voltage (AC outlet) matches the voltage rating of the device and that the AC outlet is protected by a residual current circuit breaker. Failure to do so could result in damage to the device and possibly injure the user. Unplug the device before electrical storms occur and when it is unused for long periods of time to reduce the risk of electric shock or fire.
