Trouble Shooting Guide

No sound when using any input (CD player, Line In, Wired Microphones, Wireless Microphones):

1.DELTA X main power should be turned ON. The green ON LED should be lit. If it does not light when the system is switched on, the battery is most likely too weak and needs to be plugged into the charger.

2.Make sure the main power switch is set to ON and not MUTE.

3.Check the setting of the MASTER VOLUME control. This control sets the amount of audio coming out of the speakers. If it is set to minimum, no sound will be produced.

No sound when someone speaks into the wireless microphone:

3.Microphone/transmitter power should be turned on. If the LCD display does not show, the batteries are most likely too weak. Plug the microphone/transmitter into the charger (if the batteries are rechargeable) or replace with alkaline batteries.

NOTE: Do not attempt to charge alkaline batteries! This can result in severe damage to the transmitter that will NOT be covered under warranty!

4.The transmitter and receiver should be set to the same channel and the blue RF LED (A or B) on the receiver should be lit.

5.Verify that the receiver and transmitter are in the same frequency group.

•Turn the receiver off and then on again. The letter code for the frequency group will be shown briefly on the LED display.

•Open the battery compartment of the transmitter and find the frequency group sticker. The letter on the frequency group sticker must match the letter code shown on the receiver display.

6.Make sure the red LED (on the belt-pack transmitter) is not flashing.

The wireless microphone is experiencing drop-out or interference:

1.The wireless frequency being used may not be a clear channel. Turn the transmitter off and press the SCAN button on the receiver to find a clear frequency. Then make sure to select the same channel on the transmitter.

2.Squelch adjust on the receiver is set too high. If this squelch is set too high (fully clockwise), this can drastically reduce the range of the transmitter, resulting in more frequent dropout.

3.Squelch adjust is set too low. In areas of severe interference (large downtown urban areas, airports, military bases, etc) it may be necessary to turn the squelch up slightly to avoid outside interference.

4.Transmitter is out of range of receiver. The transmitters do have a maximum range of about 300-350 feet in an open field environment. This range can be dramatically reduced indoors and when large objects (such as a wall) may be obstructing the path directly between transmitter and receiver. If this is the case, it may be necessary to position the two closer together.

5.Batteries are very weak. Just before the batteries are about to die, the overall performance of the system can degrade dramatically. Make sure to check the battery status of both the transmitter and DELTA X system.
