2-2. Uses of Service Mode
1. 2. Turn off the power with the POWER button in the front panel. The red POWER LED lights on. Press the POWER button in the front panel with pressing the UP () and DOWN () buttons, and the system enters the service mode. When no signal is input to the selected input terminal, the following functions are disabled. Press the MENU button, and the main menu is displayed. Then go to page 2 of the main menu with the UP () or DOWN () button, then select the MAINTAIN icon on the bottom line, and then press the OK button. In this menu screen, the version number and released date of the internal software can be checked. The structure of the MAINTAIN menu is shown below.
MAINTAIN CONFIGURATION COLOR TEMP 9300K SUB-BRIGHTNESS R 6500K G B EXIT SUB-CONTRAST R G B EXIT INITIAL EEPROM CLEAR ETI TIME EEPROM TEST RGB RESET EXIT CHIPS AGING MODE ON OFF REGISTERS VALUE CONTROL REG EXIT EXIT 000~1FF
The operation procedure is basically same as that of the ordinary user controls. The function of each menu is explained in next section.

2-3. Functions of Service Mode
1. COLOR TEMP This is used for the white balance adjustment at color temperature 9300 K and 6500 K. The adjustment requires to be done for every input (INPUT1: DVI-D, INPUT1: HD15, or INPUT2: HD15) by switching the input. The adjustment data is stored into the register for respective inputs. INITIAL EEPROM This sets the data of the EEPROM to the default data. This operation is not required usually. CLEAR ETI TIME This resets the ETI (Elapsed Time Indicator) counter to 00000 H. EEPROM TEST This tests writing and reading of the EEPROM. RGB RESET This adjust the offset and gain of the input AD converter for the analog inputs (INPUT1: HD15 and INPUT2:HD15). As these adjustments are common to both inputs, perform them for either input. It is unnecessary for another input. Execute the adjustments under the condition where the signal specified in "White Balance Adjustment" is input. AGING IN MODE This sets and clears the NO SYNC AGING flag. AGING MODE = ON: Sets the NO SYNC AGING flag. AGING MODE = OFF: Clears the NO SYNC AGING flag. When the NO SYNC AGING flag is set and the input with no input signal is selected, the system goes into the BURN IN mode. The NO SYNC AGING flag is held until it is cleared. To clear the NO SYNC AGING flag, go into the service mode and then set the AGINGN MODE to OFF, or execute the all mode recall. CONTROL REG. This can check the data of the internal registers. This operation is not required usually.
2-4. White Balance Adjustment
< Preparation > (1) Measurement point : Center of screen (2) Measurement distance : 50 cm (3) Measurement angle : 90 (4) Color analyzer (Minolta CS-1000 or equivalent) (5) Signal generator (Astro Design VG-828D or equivalent) Be sure to calibrate the analog RGB output level with 75 termination. 1. Service mode setting Enter the service mode referring to step 1 and 2 of Section 2-2. Aging Set the AGING MODE in the service mode to ON. Disconnect the signal input terminal or select the input with no signal input, and the system goes into the AGING MODE. Execute aging for 30 minutes or more. User control setting Feed a signal to the selected input, and then execute reset in the menu screen. Then, move the menu display position to avoid the measurement point. Or, set the following for respective inputs. BACKLIGHT (Brightness of backlight) = 100 CONTRAST = 70 BRIGHTNESS = 50 Menu display position = not center of screen (Avoid the measurement point.) (The setting of the menu display position is common to respective inputs.) ECO = OFF (The setting of ECO is common to respective inputs.) Do not change the above setting until the white balance adjustment is completed.

ERVICE BULLETIN

Installing Redundant Audio on Acuity Systems with the SunBlade 150 CPU
Welch Allyn offers this feature on all Acuity Systems that utilize a Flat Panel display(s) with integrated speakers. The following Flat Panel display models support this feature: Sony SDM-M81 1. 2. 3. 4. Sony SDM-X82 Sony SDM-X93
Ensure that your Acuity System is using one of the Flat Panel displays listed above before proceeding. On the rear of the Flat Panel display with the Acuity Map, locate the Audio-In connectors. Refer to Figures below for assistance in identifying Flat Panel display connections. Insert one end of the 3.5 mm male stereo cable into the Audio-In jack, next to the video connector in use. Typically, the Acuity System will be using Input 1. If the Acuity System consists of a Primary / High Availability (HA) pair of CPUs, connect an additional stereo cable to Input 2.

On the rear of the SunBlade 150 CPU, identify the Headphone Jack. The Headphone Jack has an orange bezel ring around it, and is located closest to the Serial Port connector. Refer to Figure 4 below for assistance in identifying the Headphone Jack on the rear of the CPU. Connect the other end of the stereo cable to the Headphone Jack. DO NOT CONNECT THE CABLE TO THE LINE-OUT JACK! If the Acuity System consists of a Primary / HA pair of CPUs, ensure that you also connect the additional stereo cable to HA CPU. Trace the video cables from the Acuity Map display back to each CPU if required. Ensure that the video and audio cables from each CPU are coupled together to the proper Flat Panel display input channel. Note that mixing of video and audio cables from different CPUs will cause the Redundant Audio feature to not work properly.
Figure 4: SunBlade 150 CPU Rear View
NOTE: USAGE OF THE LINE-OUT JACK WILL NOT WORK FOR THE REDUNDANT AUDIO FEATURE. THE HEADPHONE JACK MUST BE USED.
8. At the Acuity System, initiate an audible alarm for a patient currently being monitored. 9. Ensure that an audible alert is heard from the Flat Panel display integrated speakers. 10. If the Acuity System consists of a Primary / HA pair of CPUs, use the Input control switch on the right hand side of the Flat Panel Bezel display, to switch back an forth between one CPU and the other, testing the Redundant Audio feature from both CPUs. 11. Use the Volume control switches, on the right hand side of the Flat Panel display bezel, to adjust the audio to the desired volume level. Typically, these are labeled as shown in Figure 5 below. Note that this adjustment will not affect volume levels from the internal CPU speaker, which is controlled by the Acuity software application.
