14. TIPS & TROUBLESHOOTING
14.1. Tips for Maximum Performance
•
Keep a clear and unobstructed path between transmitter and receiver.
•
Position receiver antennas at least one meter off the performance floor level.
•
Avoid placing receiver antennas near large metallic or other dense materials.
•
Keep receiver antennas away from RF signal generating equipment (computers, high-
voltage equipment, etc.).
•
Position dipole antennas perpendicular to each other.
•
Use a Sabine Antenna Distribution System (SWA6SS) for multiple system installation.
•
Return transmitters to a charger when not in use.
•
Use a Sabine SWASS-EXT Extension Antenna to extend range and/or improve recep-
tion.
14.2. Troubleshooting
Problem: Receiver and transmitter power are on, receiver RF Signal meters and Input
Level meters are lighting up, but there is no sound from system.
Solution: Check connection between receiver and mixer/amp. Adjust receiver Output Level
control. Check for MUTE status in Remote Control Software. Make sure RF scan-
ner is OFF.
Problem: Receiver and transmitter power are on, but receiver RF Signal meters and Input
Level meters are not lighting up.
Solution: Check transmitter On/Battery Indicator. Recharge transmitter if necessary. Check
transmitter and receiver frequency Channel settings (make sure they match).
Check receiver antenna connections. Check distance between transmitter and
receiver antennas and possible obstructions in path.
Problem: Transmitter is on, but sound is noisy.
Solution: Check transmitter On/Battery Indicator. Replace weak battery with fresh battery
from charger unit if necessary. Check for other sources of RF interference (high
voltage equipment, lighting equipment, etc.). Check distance between transmit-
ters and receiver antennas.
Problem: Transmitter is off, but noise still coming from receiver.
Solution: Check for other sources of RF interference (high voltage equipment, lighting
equipment, trolley cars, etc.). Select another frequency. Check connection and
position of the receiver antennas. Utilize a Sabine Extension Antenna.
Problem: Noise or humming.
Solution: Check for fluorescent lights — bad ballasts may cause noise or hum in your
system.
Problem: Ticking sounds, interference, dropouts, or reduced distance?
Solution: First, try another channel at least 10 channels away from the one you are trying.
Keep moving the channel selection until you find an RF channel with better
performance. Or, better yet, use the included SWM Remote Software to perform
an RF scan which will clearly display available clear channels. If symptoms
persist, check antenna orientation on the receiver and make sure the antennas
are mounted on the side facing the transmitters (front or rear).
Check your RF Scan and make sure the RF levels of both antennas are approxi-
mately equal when displaying a Sabine transmitter. If the levels are radically
different, then you may not have true diversity. In this case, check your antenna
connections for a bad cable or connector.
Are there any wireless local area networks (LAN) in the vicinity? Are there any
microwave ovens in the vicinity? Try turning these items off and see it the problem
persists. Your scan should also expose potential interference from these items.
Choose channels without potential interference.
Problem: “ERROR 1” message displays on receiver:
Solution: Make sure that the #1 dip switch (located on the rear panel of the receiver) is in
the down (OFF) position.
See page 55 for a complete chart of DIP switch settings.
