PREVENTIVE MEASURES:
- Please read the attached safety instructions as well as the following instructions carefully.
- Please keep all the instructions.
- Please use the device only as intended.
- Please respect the valid waste management rules. Please deliver the packaging divided into plastic and paper/ cardboard to the recycling management.
- Please refer all servicing to qualified personnel only if the device is damaged, exposed to liquid/rain or if it does not operate normally.
- Please, do not expose to any kind of heat such as ovens, radiators, or any other devices (incl. amplifiers). Please check for enough distance between amplifiers and walls, racks, etc. to prevent overheating.
- After connection please check the wiring to prevent any kind of accident or damage.
Please never use any kind of damaged cable and wiring. - Only use authorized and stable stands, brackets, shelves, tables etc.. for installations. Please check for adequate stability against collapse.
- Appearance of interferences when using wireless systems.
The simultaneous use of wireless microphones and of mobile phones (if both devices are not very distant from each other) can lead to the appearance of interferences in the microphone signal which can be heard in the PA system.
CAUTION:
To reduce the risk of electric shock, do not remove cover (or back). No user serviceable parts inside. Refer servicing to qualified personnel.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk to persons.
The exclamation mark within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.
CAUTION! HIGH VOLUME!
You will operate this transmission system for professional use. Therefore the commercial use of this equipment is liable to the rules and regulations of the Accident Prevention & Insurance Association of your industry sector. Adam Hall as a manufacturer is bound to inform you formally about the existence of eventual sanitary risks.
This system is able to induce an acoustic pressure of 80 db. 85 db is by law the maximum audio pressure level which your ear can be exposed to during a work day. It was set according to the technical expertise of the occupational medicine as a basis for the noise rating level. Higher sound levels or longer exposition times could damage your ear. The time of exposition by higher sound pressure levels should be shortened in order to prevent from ear damages. Here are a few reliable warning signals which show that you have exposed yourself for a too long period to excessive sound pressure levels:
- You hear bell- or whistling sounds!
- You have the impression that you can't hear high tones anymore!
