Sennheiser SR 3254, SR 3256 Setting up the transmitters, y Ventilation in fixed installations

Setting up the transmitters

The SR 3254 and SR 3256 transmitters heat up during operation.

y Ventilation in fixed installations

Ensure sufficient ventilation, especially when the transmitters are mounted into a desk or chassis. Provide for a duct of sufficient size to ensure a free air flow between the trans- mitters.

ySufficient ventilation in a rack

When operating several transmitters in a rack, ensure sufficient ventilation or cooling. We recommend not stacking more than two transmitter directly one above the other, and then providing for a duct of sufficient size to ensure a free air flow between the transmitters.
