2. REPAIRING MEASURES
* Check the unit as the following ways when you happen to meet situations mentioned in
table.
Status Confirmation Management
Power not supplied Is the Power supplied
normally? Reconnect the Power after confirmation
Power is being supplied
normally, but the unit doesn't
work
Is the right fuse and voltage
you are using? Check the fuse and control the input voltage of S/W in normal
Data LED is not working Is Data Line connected
normally? Check the state of Data Line Connection
Operates up & down, but
doesn't operate left & right Isn't the unit being fixed in AUTO PAN function? Off the AUTO PAN function
Data LED is operating, but the
Pan/Tilt doesn't work
(1) Is the address of DIP
S/W correct?
(2) Is the socket in right
position in COMM SEL box?
1) Off the power and fix a correct
DIP Switch
(2) Check again the socket's position
in COMM SEL box
There's a trouble at a
revolution speed of PAN/TILT Is the right voltage selected? In the Pan/Tilt power selecting box,
confirm the right connection
Zooming is operating in
opposite way Insert the socket oppositely in LPC
box
Doesn't operate left & right Is the unit in AUTO PAN
function? Off the Auto Pan function at Keyboard
