Restricted Proprietary and Confidential Information
When the CDP is installed and the extended range dimmer bus mode is to be used, the lower third of the dimmer
bus input voltage must be adjusted prior to use. To do this:
 Set the brightness mode to use extended dimmer bus mode.
 Using the dimmer bus, adjust the display to the lowest visible setting.
 When the display is showing the Main Menu, the ► right arrow on the CDP will adjust the display refresh
rate.
 Repeatedly pressing the ► right arrow will cyclically go through the 11 possible refresh rate adjustments.
 Go through all the settings until the best setting is found.
 Turn the dimmer bus up and down in the lower third of the dimmer bus input’s settings (the lower third of
the dimmer bus knob’s travel) to make sure that all the low dimmer bus settings are good.
 After the best setting is found, the setting will be saved 2 minutes after the last adjustment. This saved
setting will be recalled every time the unit is powered on.
Note: The ► right arrow may be used to adjust the refresh rate whenever the CDP is displaying a menu (as
opposed to displaying a data entry screen, for example). Again, the last refresh rate adjustment will be saved 2
minutes after the user has completed the adjustment. This feature is not available in Standalone mode or FW Ver
5.x.

 Optical Gain (Values from 00 to 99)
 Night Time Max (Values from 05 to 15)
 Daylight Thresh (Values from 0 to 9)
 Dimmer Thresh (Values from 0 to 9)
 Dim Bus Voltage (Values from 00 to 35)
4.4.3 SYSTEM SETUP
Main Menu  System  System Setup
Caution: When using the extended dimmer bus mode, the display can be turned off by turning the dimmer knob all the way down. This
is different than the standard dimmer bus mode which can be set to make the display go to daytime brightness levels if the dimmer bus
is turned all the way down. The reason for the difference is that for the normal dimmer bus mode, turning the dimmer bus all the way
down is interpreted by the CDP as the user turning off the dimmer bus (i.e., it is daytime). This is not interpreted in the same way for the
extended dimmer bus mode. In this later circumstance, having the display go to daytime levels as a result of turning the dimmer bus
down may cause an uncomfortable glare in night vision goggles.
