The 482C15 has internal jumpers that are accessed by opening the top cover. The top cover is secured by four (4)
Philips head screws on the bottom of the unit. Place the unit on a clean, flat surface (Electrical Static Discharge
protection recommended) and remove the four screws. Carefully rotate the unit and place it on its feet, then gently
remove the cover.
The various jumpers are all labeled on the PC board. Each channel can be set to your selected gain and other options.
The selection of all these features with jumpers allows the 482C15 to have the functionality of many other higher priced
units at an economical cost. See the table that explains the function and number of each jumper. “X” represents channel
number. Once jumpers have been placed as needed, replace cover – taking special care to align the front and back
panels with the slots in the top cover. Insert the four (4) screws and tighten to 5 in-lbs.
