CHAPTER 3
Operation
General Instructions
1.Attach the power pack to the DSI 2008.
2.Apply power to all components.
3.Confirm the power indicator is lit on the DSI 2008 front panel.
NOTE: The power indicator flashes when a call signal is received from a 2-wire line, if the call signal option board is attached. The DSI 2008 level displays should help to confirm which line is calling.
4.Use the level adjust trimmers (Figure 8) to fine tune the listen levels.
NOTE: For 4-wire systems other than ADAM, ADAM CS, and Zeus, you may have to change the setting of the 4W LEVEL REF SEL control to establish the correct level. For 2-wire system other than Audiocom, TW, and Clear- Com, you may have to adjust the level at the 2-wire system if you cannot establish the correct level with the 2- wire listen level trimmers.
