Solution 3: Set the MS-500 termination switch to
―ON‖.
Cause 4: headset cable is too long or quality problem.
Solution 4: Change or short headset cable
Problem: Excessive crosstalk
Cause 1: High DC resistance on ground return.
Solution 1: Use heavier cable; add additional conductor(s) to ground return.
Cause 2: Headset cables are not wired properly or shielded properly.
Solution 2: Correct wiring. Use headsets with properly shielded wiring.
Problem: Hum or buzz in system
Cause 1: No earth or bad earth.
Solution 1: Check earth ground of jack. Make sure jack to be connect with earth well.
Cause 2: Inductive pickup caused by close proximity of this main station or connected remote
stations to power lines or transformers.
Solution 2: Relocate the offending unit.
Cause 3: Intercom line cable is not wired properly; the shield of cable is not connected to Pin 1 of
XLR-3
Solution 3
: Check intercom line cable. Make sure all the cables‘ Pin-1 of 3-XLR connects correct.
Cause 4: 10 Ohm chassis ground resistor is shorted.
Solution 4: Bridge a 10 Ohm resistor between system ground (G) and earth ground (
) of any
power supply.
If this condition occurs, it is because the system ground came into contact with something
that was "HOT" with respect to the power supply earth ground. Carefully check the system
ground and AC distribution in the area.
WARNING: THIS IS A POTENTIALLY DANGEROUS SITUATION. A SHOCK HAZARD MAY
EXIST BETWEEN A REMOTE STATION HEADSET AND GROUND.
Problem: Can not turn on the Mic function on all the beltpacks
Cause 1: The connection among TELIKOU main stations must go via
―Online‖ connector on rear
