dierently.
1. Cable Testing (short press) : With the CM200 o, each short
press of the button causes a cable test to be executed and the
results displayed for 20 seconds before powering o. “TEST” is
displayed while testing is being performed. If another short press
occurs before the 20 second time out another test and 20 second
time out begin. If the button is pressed and held until “LOOP” is
displayed and then released, tests are run continuously and the
display updated. The CM200 will turn o automatically if there is
no test result change for 5 minutes. A long press of the button will
cause the CM200 to exit cable test loop mode and enter mode
selection as discussed below.

long press of the button will cause the CM200 to enter mode
selection. In mode selection the CM200 cycles through cable test

automatically 30 minutes after the test button press or by exiting
to mode select with a long press.
