telephone cables with RJ-11 plugs/jacks are
wired inverse. The CABLE
SNIFFER-REMOTE will show that a cable like
this is crossed. A cable like this reverses the
polarity of the telephone line. Most regular
telephones made in the last 10 years are not
polarity sensitive. So, even though the cable
is wired in reverse (crossed), it may work OK.
Early touch-tone telephones and answering
machines were polarity sensitive. If connected
in reverse polarity, the touch-tone phone may
not dial out (no touch), and the answering
machine may not answer when the line rings.
MAINTENANCE
Your CABLE SNIFFER-REMOTE is a precision test
instrument and, when used as described in this manual,
should not require maintenance. There are no internal
adjustments. Calibration is not required. To clean the
outside of the tester, use a cloth dampened with a mild
detergent solution. Do not use any abrasive cleansers
or chemical solvents that may damage the case of the
tester.
The group of products may be discontinued, models
specifications, price or design changed at any time
without notice and without incurring any obligation.
