the SEL key to initiate a new test cycle�
The remote diagnostic test verifies that
the two redundant ID’s in the remote
unit are both functional� If either of the
two redundant ID’s is defective, no ID
number will be displayed in diagnostic
mode� During normal cable test, the
TestifierPRO
f
needs only one of the
two redundant ID’s to be functional to
recognize and display the remote ID�
Battery Low Detection – The
TestifierPRO
f
monitors battery status
continuously when it is powered on�
When the battery low icon is activated,
battery voltage has dropped to below
6.4V. The battery should be replaced as
soon as practical. Below 6.0V, the LCD
display could dim or appear turned off
even though the TestifierPRO
f
is still
operating (for example, the EL backlight
can still be toggled�) Cable testing
results becomes unreliable when battery
voltage drops below 4.5V.
EL Backlight – At power on, the EL
backlight is initialized to off to conserve
power. While the TestifierPRO
f
is on
the backlight can be toggled on and off
by momentarily pressing the power key
(for less than 2 seconds)� The backlight
turns off automatically roughly 3 minutes
