General Information

Safety information
● Before operating the system, check that the
   operating voltage indicated on the typeplate (or
   the voltage indication beside the voltage
   selector) of your system is identical with the
   voltage of your local power supply. If not, please
   consult your dealer.
● Place the system on a flat, hard and stable
   surface.
● Place the system in a location with adequate
   ventilation to prevent internal heat build-up in
   your system. Allow at least 10 cm (4 inches)
   clearance from the rear and the top of the unit
   and 5 cm (2 inches) from each side.
● The ventilation should not be impeded by
   covering the ventilation openings with items,
   such as newspapers, table-cloths, curtains, etc.
● Do not expose the system, batteries or discs to
   excessive moisture, rain, sand or heat sources
   caused by heating equipment or direct sunlight.
● No naked flame sources, such as lighted candles,
   should be placed on the apparatus.
● No objects filled with liquids, such as vases, shall
   be placed on the apparatus.
● Don’t expose the system to dripping or
   splashing.
● Install this unit near the AC outlet and where the
   AC power can be reached easily.
● The lens may cloud over when the system is
   suddenly moved from cold to warm
   surroundings, making it impossible to play a disc.
   Leave the system in the warm environment until
   the moisture evaporates.
● The mechanical parts of the set contain self
   lubricating bearings and must not be oiled or
   lubricated.
● When the system is switched to Standby
   mode, it is still consuming some power.
   To disconnect the system from the
   power supply completely, remove the AC
   power plug from the wall socket.
  
IMPORTANT!
PLEASE NOTE THAT THE VOLTAGE SELECTOR LOCATED AT THE REAR OF THIS SYSTEM IS PRESET AT 220V FROM THE FACTORY. FOR COUNTRIES THAT OPERATE AT 110V-127V, PLEASE ADJUST TO 110V-127V BEFORE YOU SWITCH ON THE SYSTEM.

Description : EPAD® MICROPOWER CMOS OPERATIONAL AMPLIFIER

GENERAL DESCRIPTION
The ALD1721E is a monolithic rail-to-rail precision CMOS operational amplifier with integrated user programmable EPAD (Electrically Programmable Analog Device) based offset voltage adjustment. The ALD1721E operational amplifier is a direct replacement of the ALD1701 operational amplifier, with the added feature of user-programmable offset voltage trimming resulting in significantly enhanced total system performance and user flexibility.
