To display memorized error (Protective operation)
status:
1. Turn power on.
2. Press the CHECK button on the remote controller
continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote
controller. The code "H00" (no abnormality) will be
displayed and signal will be transmitted to the main
unit. The power LED lights up. If no abnormality is
stored in the memory, three beeps sound will be
heard.
5. Every press of the button (up or down) will increase
abnormality numbers and transmit abnormality code
signal to the main unit.
6. When the latest abnormality code on the main unit
and code transmitted from the remote controller are
matched, power LED will light up for 30 seconds and
a beep sound (continuously for 4 seconds) will be
heard. If no codes are matched, power LED will light
up for 0.5 seconds and no sound will be heard. 7. The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5
seconds or operating the unit for 30 seconds. 8. The same diagnosis can be repeated by turning
power on again.
To clear memorized error (Protective operation) status after repair:1. Turn power on.
2. Press the AUTO button for 5 seconds (A beep
receiving sound) on the main unit to operate the unit
at Forced Cooling Operation mode.
3. Press the CHECK button on the remote controller for
about 1 second with a pointed object to transmit
signal to main unit. A beep sound is heard from main
unit and the data is cleared.
• Temporary Operation (Depending on breakdown status)
1. Press the AUTO button (A beep receiving sound) on
the main unit to operate the unit. (Remote control will
become possible.)
2. The unit can temporarily be used until repaired

Dell backlight indicators


A computer monitor has a front-mounted LED that displays its current status and flashes in the event of an error. When an error occurs, the flashing may be accompanied by an error message on the screen. If the screen does not display an error message, the problem most likely falls into one of four common categories.

Unsupported Display Mode A video card has the ability to send output to the monitor at many display resolutions and refresh rates. However, no single monitor is capable of supporting every possible display mode. When the video card sends an unsupported display mode to the monitor, the monitor shuts off to prevent damage and blinks, or displays an error message. Standby Mode b> When a monitor detects no video signal from the computer, it assumes that you have turned the computer off and enters standby mode to reduce power consumption. Dell and HP monitors display an amber light when in standby mode. The status light on an Apple monitor blinks slowly. Incorrect Power Supply Some monitors such as certain Apple Cinema and Studio displays use external power adapters. Because different power adapters may have similar connectors, these monitors are designed to detect when an incorrect power supply is connected and blink the status LED rather than attempting to turn on. In the case of an Apple display, the LED blinks in an alternating short and long pattern. b> Backlight Failure b> A flat panel LCD display has an LED or fluorescent backlight that illuminates the pixels and makes it possible to see the contents of the screen. If the backlight fails and requires replacement, the monitor is unable to display any information. In some cases, you may be able to resolve this issue by turning the monitor and computer off, disconnecting and reseating all cables. If the monitor still has a backlight issue, it requires professional service.

My printer is not printing anything. the status light isnt even on what should i do?


Does the "Status Monitor" in your printer display any errors?
Is the printer cover securely closed?
Is any of the LEDs in the printer flashing?
What happened just before the printer stopped working? Did you have a poer failure? Did you install new software or hardware or a Windows update?

Please, report back the status (ON, OFF, BLINKING) of the following LEDs:

TONER
DRUM
PAPER
STATUS

I have connected Lantronix UDS1100 Device with Siemens AZL Meters. But not able to get complete data on front end.


The UDS has the following LEDs, which help you diagnose problems.
Power LED (green)
Ethernet 10/100 Link (yellow = 10 Mb/green = 100 Mb)
Ethernet Half/Full Duplex Activity (yellow = Half Duplex/green = Full Duplex)
Diagnostic (red)
Status (green)
Simultaneously lit Diagnostic (red) and Status (green) LEDs mean something is
wrong. If the Diagnostic LED is lit or blinking, count the number of times the Status
LED blinks between its pauses. The following table explains the LED functions:

Diagnostic Indicator


Beep codes and power LED status are pre-post errors. Usually beep codes indicate a problem with a memory module. Power LED is solid green for normal operation. Solid or blinking Amber color power LED indicates a power distribution problem.
