 === Connection to Monitor Photodiode ===
-Either of the two configurations of the monitor photodiode seen in <imgref mon_pd> will work for the signal proportional to the laser diode power for operating in Constant Power mode.
+Either of the two configurations of the monitor photodiode seen in <imgref mon_pd> will work for the signal proportional to the laser diode power for operating in Constant Power mode.  Depending on how you have completed the monitor photodiode circuit, you may have to adjust the [[slice:dcc#constant_power_mode|sign of the Constant Power feedback loop]].

 ==== Setting the Operation Mode ====
 The SLICE-DCC has two operation modes: Constant Current and Constant Power.  The operation mode, as with most other operating parameters can be set independently for each channel.  To toggle between Constant Current and Constant Power modes, from the Home screen, touch the window labelled either CH X Constant Current or CH X Constant Power.  If the channel is in Constant Current Mode, you will be presented with the window seen in <imgref cc_param>. \\
