03 GUIDELINES AND RECOMMENDATIONS For Best Performance Compatibility The transmitter and receiver must be of the same frequency band and set to the same channel in order to work together. The R300 is available in four frequency bands, A, B, C and E (Europe only). The band information is available in the serial number label on the receiver, the serial number label on the handheld transmitter, and on the back panel label on the bodypack.
adversely affect the performance of your wireless system. It is always best to place the receiver as far away as possible from these devices to minimize potential problems. Analog and Digital Television stations can also interfere with your wireless system. The R300 is designed to operate over 16MHz of RF bandwidth, which covers 3 US TV stations.
04 TROUBLESHOOTING GUIDE Problem Possible Causes No audio and no display on the receiver Receiver is off Transmitter is off Make sure that the power supply is properly connected and the on/off button is in the on position. Turn on transmitter power switch. No audio and no RF signal indicator on the receiver display Transmitter is on a different channel or is a different band Check band information on serial number label and match to receiver, reset channel (see section 2.1).
Problem Interference Possible Causes Another wireless product in the area is on the same frequency or the signals are mixing Receiver is too close to digital signal processor or similar device Strong electromagnetic field from stage lighting or other source near the transmitter or receiver, which may be producing RF noise at or near the operating frequency RF reflective metal obstacles between the transmitter and receiver Poorly oriented beltpack antenna Short range or drop-outs Squelch set too high Faul
05 FREQUENTLY ASKED QUESTIONS Frequently Asked Questions Q: How can I make sure my R300 system’s frequency band will work in my location? A: If you will be using your system in the USA, you can check R300 compatibility in your location by using the frequency band selector located at http://www.electrovoice.com/frequencyselector. If you are outside of the USA, please contact your local Electro-Voice dealer or technical support center.
Frequently Asked Questions Q: Why did I suddenly begin getting interference? During sound check, everything was fine – but after the show began, I started getting interference. A: Another radio system that wasn’t on during sound check began transmitting on, or near your system’s frequency. If this happens, ClearScan you system again to find a new, clear frequency. Q: I’ve hear the term line-or-sight.
05 FREQUENTLY ASKED QUESTIONS Frequently Asked Questions Q: Where is the EZsync port on the R300 handheld transmitter? A: The EZsync port is located under the handheld transmitter’s removable battery cover. Just as you would do in order to change the batteries, you must loosen the battery cover to expose the EZsync port and aim the port directly at the receiver’s EZsync port during the syncing operation. Q: Sometimes I can’t get EZsync to work properly.
