 The list of board slot numbers on the left hand side of the ICE Control GUI will illuminate, indicating which boards are installed. Boards can be selected from this list by clicking on the numbers to navigate to the control options for the corresponding ICE board.
 =====Locking a Laser to Spectroscopy=====
-After making all the necessary connections you will need to find spectroscopy. This can be done by enabling the laser through the ICE CS1 menu and setting the **Laser Current** to a value which gives the desired output (see <imgref step_1>). From there, modify the setpoint temperature of the QT1 card to the temperature specified in your D2-100's documentation. To do this, first ensure that the **T Min** and **T Max** temperatures are configured to safe values for your system, then click on the **TSet(C)** field to enter a new value with the keyboard. For the D2-100 it is recommended to set **Stage 1** (Top) to 25°C, and to keep **Stage 2** (Bottom) between 15°C and 30°C.

 If using a D2-100 DBR laser purchased from Vescent, refer to the documentation which came with the laser to find the approximate **Stage 2** setpoint. Once the desired value is entered, click the **Servo: Off/On** button to engage the temperature servo. The **Temp(C)** field displays the measured temperature of the thermal plant, and **TError(mK)** displays the difference between **TSet(C)** and **Temp(C)** while the values are within the range of the monitor. **TError(mK)** is plotted in the graph below.

-If your D2-100 documentation is unavailable, start by setting **Stage 2** to 15°C, engage the servo, then increase it 0.5°C at a time until spectroscopy is found or 30°C is reached. Assuming that **Ramp** is enabled, and the value of **Range** is non-zero, this should be a reliable method to find spectroscopy.
+It is now safe to enable the laser on the CS1 card. Check that the current limit, and current setpoints are both within the specified range found in the laser documentation, then click the "Laser On/Off" button next to the current dial.

 Once spectroscopy has been found, align the feature you want to lock to with the center line on the GUI plots. You can do this either by changing the **Laser Current** supplied to the diode, or by shifting the **Center** dial in the **Ramp** box. Turning **Range** up and down will make your ramp amplitude larger or smaller and show you more or less of your spectroscopy. Whatever is lined up with the center line on the plots is the feature the ICE Box will try to lock to. If you want to lock to a peak, align the top graph with the peak you want, and note that the bottom graph's peak lock signal should be near the middle of a slope.

-<WRAP center round important 100%>The intuitive thing to do is to center right on the feature you want, but you actually want to be a little bit offset from that. The ICE Box gives a slight kick when the servo is engaged, so if you're perfectly centered on a feature it can sometimes bump you over to the next peak. It doesn't matter which side you offset from (a little right or left will be fine) as long as you're still on the correct slope. The servo will always kick towards the center of the selected slope. It's recommend to aim for a roughly 5% offset from center when aligning the feature you wish to lock to.
