provided. Do not block these air inlets and outlets when mounting the
Remote Unit. The size of each opening must equal at least 12 x 12 cm (144

remains as safe as the mounting designed by the manufacturer. Ensure that the
static and dynamic strengths are adequate for the environmental conditions of the
site. The mounting itself must not vibrate, swing or move in any way that might cause
damage to the Remote Unit.
