Wiring Example; Error Detection - LD Systems LDU500CS4 SERIES Manual De Usuario

DAISY-CHAINING
The combination of multiple receivers when daisy-chaining is not freely possible for
reasons of intermodulation.
The maximum number of U508CS4 receivers is 1.
The maximum number of U505CS4 receivers is 2.
The maximum number of U506CS4 receivers is 2.
For example: To combine 5 receivers intermodulation-free, you will need 1 x U508CS4,
2 x U505CS4 and 2 x U506CS4.
Make sure that the receiver is configured as a master or slave unit BEFORE the wiring
is done, and that the wiring of the devices forms a "circle", i.e., both data link sockets
of all receivers must be used (example: left socket master -> right socket slave 1, left
socket slave 1 -> right socket slave 2, left socket slave 2 -> right socket master).

DISPLAY
Receiver: Reception is not displayed on
antenna A or B.
Receiver: Display light is off
Receiver: Reception is not displayed on
antenna A or B.
Microphone Station: Device is turned on.
Charge status of the batteries is ok.
Receiver: Antenna A or antenna B is displayed.
Receiver: Radio signal is displayed
Transmitter and receiver: "LOW BATTERY" is
displayed.
Receiver: AF PK peak indicator is displayed
on the receiver display.
SOLUTION
Check if the microphone station is turned on.
Check the batteries in the microphone station.
Check the power supply in the transmitter.
Check whether the radio frequency of transmitter and
receiver match.
Reduce the distance between transmitter and receiver.
Make sure that there is a direct line of sight between the
transmitter and receiver.
Make sure that the antennae of the receiver are pointing
upwards and in a V-shape.
Reduce the amount of noise reduction (SQUELCH)
Check the ATTN setting on the microphone station.
Remove possible sources of interference (digital devices,
other wireless systems).
Increase the level of noise reduction (MUTE level) on the
receiver.
Replace the batteries in the microphone station.
Increase the level attenuation ATTN in the microphone station.
