Please observe the following safety tips and precautions to ensure hazard-free use of the 508.

Usage precautions

Electrical interference

For safety considerations, the 508 has been designed to provide maximum protection against the emission of electromagnetic radiation from inside the device, and from external interference.However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves should not be placed near the 508, as the possibility of interference cannot be ruled out entirely.

Whatever the type of digital control device, the 508 included, electromagnetic damage can cause malfunctioning and corrupt or destroy data. Since this is an ever-present danger, thorough care should be taken to minimize the risk of damage.

About power

Warning Since power consumption of this unit is fairly high, we recommend the use of an AC adapter whenever possible. When powering the unit from a battery, use only an alkaline type.

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 the cable.

If the unit is not to be used for a long time, disconnect the AC adapter from the outlet.

Battery operation

Use only a 9 V (alkaline) battery (6LR61).

The 508 cannot be used for recharging.

Pay close attention to the labelling of the battery to make sure you choose the correct type.

If the 508 is not to be used for an extended period of time, remove the battery 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.

Cleaning

Use a soft, dry cloth to clean the 508. 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.

Connecting cables and input and output jacks

You should always turn off the power to the 508 and all other equipment before connecting or disconnecting any cables. Also make sure to disconnect all cables and the AC adapter before moving the 508.

Environment

Caution Avoid using your 508 in environments where it will be exposed to:

Extreme temperature

High humidity or moisture

Excessive dust or sand

Excessive vibration or shock

Handling

Caution • The 508 is a precision instrument. Except for the foot switches, do not push other parts with your feet or subject them to strong force.

Take care that no foreign objects (coins or pins etc.) or liquids enter the unit.

Be sure to turn the power to all equipment off before making connections.

Before moving the unit, turn the power off and disconnect all cables and the AC adapter.

Alterations

Caution Never open the case of the 508 or attempt to modify the product in any way since this can result in damage to the unit.
