Impractical cable routing<br />

In the case of insufficient receiving range, the following must be<br />

heeded:<br />

• Preamplifier cable must not be laid parallel to power lines<br />

• Avoid coils <strong>and</strong> loops<br />

Conditions of reception<br />

19<br />

Optimum reception conditions are achieved if the following<br />

points are observed:<br />

• Transmitte<strong>rs</strong> <strong>and</strong> receiver preamplifie<strong>rs</strong> must lie on an optical<br />

axis.<br />

• No direct sunlight or artificial light on the photodiode or focussing<br />

lens of the receiver preamplifier.<br />

• It is not permitted to transmit simultaneously with two or more<br />

transmitte<strong>rs</strong> in a single room, even if different comm<strong>and</strong>s are<br />

encoded<br />
