RECOMMENDATIONS

The following recommendations are designed to ensure that the device always functions reliably: Never open the casing! To do so would expose you to the risk of an electric shock. Should repairs prove necessary, leave them to qualified service personnel.

Avoid dust and high moisture levels, direct sunlight and extremely high or low temperature. Safeguard the device from excessive vibration. Always place the unit on a stable and horizontal surface.

See to adequate ventilation. The device should not be placed on soft surfaces (carpet, cushions, etc.). When mounting it in a rack, make sure that the rear and lateral cooling vents remain unobstructed (amp heads), resp. that the rear cooling vents remain unobstructed (combos).

Avoid leaving the unit near radiators or other

objects producing heat.

Internal components should only be adjusted or cleaned by qualified service technicians.

Ensure no object or liquid penetrates the device through its cooling vents.

When replacing a fuse make sure you fit in one of identical value!

Have the device examined by a qualified service technician in the following cases:

-the mains lead or mains switch have been damaged,

-objects or liquids have penetrated the device,

-it has been exposed to excessive moisture,

-malfunctions or abnormal operating conditions have occurred,

-the device has been dropped or the casing damaged.

HINTS

To ensure secure rack or sleeve mounting you will find two nuts on the bottom side of the amplifier for additional fastening (all amp heads).

AmpsDo only operate effects pedals in-between the instrument and the amplifier, as these devices are not designed for the supplied load of an effects loop.

- Remove the plug whenever changing a fuse.

- Only ever replace a fuse with another of the same type. Never bridge defective fuses.

- Make sure the top and bottom of the device are properly ventilated and that the vents are not blocked. In the rack, leave at least 2cm free above the unit and do not remove the feet.

- Do not subject the device to excessive vibration or hard jolts as these could damage the valves ("tubes").

- After using the device, allow around 10 minutes for the valves to cool down before moving it.

- At power-up, the valves (tubes) need at least 30 seconds to warm up before achieving operation

Each W-Pro unit has been conceived to match perfectly as a system-component within this series. Therefore best sound results can be achieved by mutual combination of these devices.

Many combinations are possible and allow gradual upgrading of several high-quality systems within different performance scales and for almost every kind of application.

readiness and a further few minutes before they can deliver full power.

-When changing the valves, replace them only with valves selected by Warwick, to avoid problems like noise, microphonism and imbalance. (special selection criteria).

-Valves can become very hot. Danger of combustion.

-Don't undertake repairs yourself.

-Only allow the case to be opened by qualified personnel. (Remove the plug).

-Repairs and valve changes should only be undertaken by qualified personnel.
