Easy Maintenance of Luminance
Level
During long periods of usage, users commonly have to adjust
the luminance level of their projector, as Xenon lamps
typically age over time. The SRX-R220/SRX-R210 has a
convenient function to help users know when to make such
adjustments. The supplied SRX Controller software allows
users to set a standard luminance level, and displays an alert
message on the LCD screen at the back of the projector
when the value changes from the standard level. With this
feature, proper and timely maintenance of the luminance
level or lamp can be performed.
Automatic Lamp Power Calibration
Function
Typically, light levels will change when changing aspect
ratios between scope and flat images. To maintain a
constant luminance level during these changes, the
SRX-R220 and SRX-R210 projectors can automatically
calibrate the luminance level by controlling the lamp
output power.

Key Lock System
The SRX-R220 and SRX-R210 are designed to be highly
secure in response to DCI requirements. They do not have
screw holes, but require physical keys to open the enclosure.
This body structure meets FIPS 140-2 SPB-2 anti-tamper
regulation stipulated by the DCI. Even if the enclosure is
opened with the physical keys, an anti-tamper sensor will
trigger the Media Block LMT-100 to immediately start
recording logs for further safety if the exhibitor has not
authorized the entry. In this case, these projectors also
delete Key Delivery Messages (KDM) automatically, so that
DCP files cannot be played back.
*The decision for who has access to the system is defined by the exhibitor.
Control of this is through the screen managment system and related operator
role settings.
