To access internal options: First, disconnect power from the unit. Then, lay the unit on a flat surface with the front panel facing forward
and the top panel facing up. Remove the top panel (two screws on each side; three screws along top edge of both front and rear panels).
Disable Front Panel Setup Button: Once setup mode is completed and control settings are stored in non-volatile memory, the front
panel Setup Button may be disabled to prevent further adjustments or tampering. To disable the Setup Button: Locate the 4-gang DIP
switch on the circuit board (see diagram below). Using a screwdriver or other implement, Move the 'opt.1' DIP switch to the left (be careful
not to disturb the other DIP switch settings). Replace the top panel. The Setup Button may again be enabled by reversing this process.
NOTE: Max Level, Sample Time, & Gain Ratio are disabled during normal operation (see below).
Enable Front Panel Controls: Once setup mode is completed and control settings are stored in non-volatile memory, the Max Level,
Sample Time, & Gain Ratio front panel controls are disabled to prevent further adjustments or tampering. However, these controls may be
enabled to allow adjustments during normal operation. Adjustments made during normal operation will not be stored in non-volatile
memory without repeating the setup procedure. To enable the Front Panel Controls: Locate the 4-gang DIP switch on the circuit board
(see diagram below). Using a screwdriver or other implement, Move the 'opt.2' DIP switch to the right (be careful not to disturb the other
DIP switch settings). Replace the top panel. The controls may again be disabled by reversing this process. NOTE: The Sense Level
control cannot be disabled. Once setup is completed, do not disturb the Sense Level control.
