16.5 CONTROLS AND INDICATORS
Figure 16-7 shows the location of all controls and indicators on the Checkback module front panel.
Figure 16-8 shows the location of all controls and indicators on the Checkback module circuit board.
These controls and indicators are described in Tables 16-1 and 16-2. LEDs DS1 through DS9 and

are accessible when the module is removed from the chassis or is on a card extender.

SW3 RESET LOG switch Manually resets the test log. This sets the TESTS RUN, TESTS PASSED, and
TESTS FAILED totals to zero.
SW4 UP switch Increases value on display, one number, each time it is pressed.
SW5 DOWN switch Decreases value on display, one number, each time it is pressed.
SW6 HC1 switch Manually activates Hard Carrier 1 when pressed and held for five seconds.
SW7 HC2 switch Manually activates Hard Carrier 2 when pressed and held for five seconds.
