Page 13

Operating range

The operating range is the distance between maximum and minimum FM reception of transmitter and receiver.

• Unwind the microphone cable for optimal operating range.

• The operating range is typically more than 10 meters (30 feet) inside and more than 30 meters (90 feet) outside.

High-power electronic equipment, larger electronic installations and metallic structures may affect and significantly reduce the operating range.

Connecting the microphone

d) Remove the microphone

e) For attaching the microphone, proceed in

reverse order.

FM receivers

Fundamental benefits of multi-frequency receivers

• Frequency synchronization Micro TX-SX can change the actual channel of the Acoustiguide Guide-U multi-frequency receivers directly over the air (see page 22). Changing the channel is quick and easy.

• Standby mode for power saving This function helps economize on power. 40 seconds after switching off the transmitter the receivers automatically enter standby mode.

The receivers consume practically no power in standby mode. They detect when the Micro TX-SX switches on again and automatically resume normal operation mode.
