The meanings of these symbols are as follows: Since power consumption of this unit is fairly high, we recommend the use of an AC adapter whenever possible. When powering the unit from batteries, use only alkaline types. This symbol indicates explanations about extremely dangerous matters. If users ignore this symbol and handle the device the wrong way, serious injury or death could result. This symbol indicates explanations about dangerous matters. If users ignore this symbol and handle the device the wrong way, bodily injury and damage to the equipment could result. Please observe the following safety tips and precautions to ensure hazard-free use of the B2. Power requirements Warning Caution Warning [AC adapter operation] • Be sure to use only an AC adapter which supplies 9 V DC, 300 mA and is equipped with a "center minus" plug (Zoom AD-0006). The use of an adapter other than the specified type may damage the unit and pose a safety hazard. • Connect the AC adapter only to an AC outlet that supplies the rated voltage required by the adapter. • When disconnecting the AC adapter from the AC outlet, always grasp the adapter itself and do not pull at the cable. • During lightning or when not using the unit for an extended period, disconnect the AC adapter from the AC outlet. [Battery operation] • Use four conventional IEC R6 (size AA) batteries (alkaline). • The B2 cannot be used for recharging. •Pay close attention to the labelling of the battery to make sure you choose the correct type. • When not using the unit for an extended period, remove the batteries from the unit. • If battery leakage has occurred, wipe the battery compartment and the battery terminals carefully to remove all remnants of battery fluid. • While using the unit, the battery compartment cover should be closed. Warning Environment To prevent the risk of fire, electric shock or malfunction, avoid using your B2 in environments where it will be exposed to: • Extreme temperatures • Heat sources such as radiators or stoves Warning Caution Warning Caution • High humidity or moisture • Excessive dust or sand • Excessive vibration or shock Handling •Never place objects filled with liquids, such as vases, on the B2 since this can cause electric shock. • Do not place naked flame sources, such as lighted candles, on the B2 since this can cause fire. • The B2 is a precision instrument. Do not exert undue pressure on the keys and other controls. Also take care not to drop the unit, and do not subject it to shock or excessive pressure. •Take care that no foreign objects (coins or pins etc.) or liquids can enter the unit. Connecting cables and input and output jacks You should always turn off the power to the B2 and all other equipment before connecting or disconnecting any cables. Also make sure to disconnect all connection cables and the power cord before moving the B2. Alterations Never open the case of the B2 or attempt to modify the product in any way since this can result in damage to the unit. Volume Do not use the B2 at a loud volume for a long time since this can cause hearing impairment. Usage Precautions Electrical interference For safety considerations, the B2 has been designed to provide maximum protection against the emission of electromagnetic radiation from inside the device, and protection from external interference. However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves should not be placed near the B2, as the possibility of interference cannot be ruled out entirely. With any type of digital control device, the B2 included, electromagnetic interference can cause malfunctioning and can corrupt or destroy data. Care should be taken to minimize the risk of damage. Cleaning Use a soft, dry cloth to clean the B2. If necessary, slightly moisten the cloth. Do not use abrasive cleanser, wax, or solvents (such as paint thinner or cleaning alcohol), since these may dull the finish or damage the surface.
