Audible Signal (Beeper)
The test tool uses an audible tone to signal different
operational conditions. A single short tone indicates a
pass condition withough a Cable ID detected. A two
frequency tone signals a pass condition with a Cable ID
detected. Three short tones signal a test failure. A long
tone sounds whenever an invalid key is pressed. A
continuous, varying-pitch tone signals the test tool is
connected to an active cable and should be disconnected
immediately. To disable the audible signal for the PASS
and FAIL conditions, see “Setup Selection".
Low Battery Indication
When the battery voltage is low bit it is OK to continue,
the test tool displays “LOW BATTERY” once during a
power-on session. When this message first appears there
will be about 8 hours of use left. When the battery voltage
is too low to continue, the unit displays “REPLACE
BATTERY”. To continue using the test tool, you must
replace the batteries. Refer to “Replacing Batteries” .
