Unpacking

As part of Turbosound's system of quality control, this product is carefully checked before packing, to ensure flawless appearance. After unpacking the unit, please inspect for any physical damage and retain the shipping carton and all relevant packing materials for use should the unit need returning.

After unpacking the unit please check carefully for damage. If damage is found, please notify the carrier concerned at once. You, the consignee, must instigate any claim. Please retain all packaging in case of future re-shipment.

There will be a small packet of spare fuses with the unit. Please keep them in a safe place.

If any damage has occurred, please notify your dealer immediately, so that a written claim for damages can be initiated. See the Warranty section at the end of this manual.

Mechanical Installation

A vertical rack space of 1U (44mm / 1.75") is required for each unit. If used in a mobile or transportable system, the unit must be supported at the rear by additional bracing or shelving, to prevent vibration-induced metal fatigue of the racking ‘ears’. Failure to do this will impair reliability and invalidate the Warranty. The rack casing will need a depth of 425mm (minimum) to clear the connectors.

Adequate ventilation must be provided by allowing sufficient room around the sides and rear of the unit to permit free circulation of air. Forced cooling is not required, a factor which aids component longevity. The front of the unit should not be exposed to long term direct sunlight as this can have a detrimental effect on the display lens.
