Power up
Screen Saver
(Main Menu > Configure > Setup > Edit Setup> Screen > Screen Saver)
Configure the screen display and Screen Saver functions. The default state for the Screen
Saver is disabled. The Screen Saver function helps to reduce backlight wear. When active,
the back light is off and nothing on the display is visible. The screen saver will not function
in Setup Menus or in test mode.
• Enabled - Toggle On and Off.
• Timeout - Only available when the Screen Saver function is active. This is how long the
Screen Saver will display on the screen. Programmable between 1 and 720 minutes in
software, when disabled the screen will remain on permanently (enter 0 to disable).
• Saver Type - Only available when the Screen Saver function is active. This is set to
Normal.
• Dim Saver - Only available when the Screen Saver function is active. Dim Saver will
help to increase the life of the backlight and lower the screen brightness for night time
use. Use Saver Brightness or Off Always.
• Saver Level - Only available when the Dim Saver function is set to Use Saver Bright-
ness. Select this to use the instant dimming slider which lowers the screen brightness.
Default screen brightness is 80%. Adjustable between 10% and 100% of full brightness.
This works on a square law rule that means if you reduce the saver level by 25% you
will double the backlight life. If you reduce the saver level by 50% you will quadruple the
backlight life. Normal backlight MTBF at 100% brightness is:
• • SIREC D300 55,000 hours (86,500 at 80% brightness)
• • SIREC D400 43,000 hours for the(67,000 at 80% brightness)
• • SIREC D200 40,000 hours (62,500 at 80% brightness)
When the configuration is complete select the Finish button to Commit, Discard or Commit
Later. Select the Back button to return to the previous menu.
Exit Screen Saver
If the screen saver is active on the recorder, any of the following will deactivate the screen
saver,
• User touches the recorder screen.
• Any USB device is plugged in or unplugged.
• On alarm - An alarm is triggered, the unit will not return to screen saver till the alarm
state is inactive and another screen saver time-out period has expired.
Charts
(Main Menu > Configure > Setup > Edit Setup> Screen > Charts)
A Chart speed is the time it takes the data to travel from one side of the screen to the other.
The recorder has up to 10 different chart speeds. There are 3 categories that can be set;
Slow, Medium and Fast (default). Set up each category to display the desired chart speed.
Limits are in place so that each speed cannot overlap. Eg. a Medium speed cannot be set
faster than the Fast speed.
