1. For best reception, the location of the receiver should be visible to the operator at all
times.
2. The location selected should not be exposed to high levels of electric noise. Mounting the
receiver next to an unshielded variable-frequency drive may cause minor interference.
Always locate the receiver as far away from a variable-frequency drive as possible.
3. Ensure the selected location has adequate space to accommodate the receiver. If an
external antenna is used, always locate the receiver where the antenna is free from any
obstacles from all directions to avoid the possibility of antenna damage (
see Fig. 24
).
