ONE YEAR LIMITED WARRANTY
The Triplett Corporation warrants instruments and test equipment manufac-
tured by it to be free from defective material or workmanship and agrees to
repair or replace such products which, under normal use and service, disclose
the defect to be the fault of our manufacturing, with no charge within one year
of the date of original purchase for parts and labor. If we are unable to repair or
replace the product, we will make a refund of the purchase price. Consult the
Instruction Manual for instructions regarding the proper use and servicing of
instruments and test equipment. Our obligation under this warranty is limited
to repairing, replacing, or making refund on any instrument or test equipment
which proves to be defective within one year from the date of original pur-
chase.
This warranty does not apply to any of our products which have been repaired
or altered by unauthorized persons in any way so as, in our sole judgment, to
injure their stability or reliability, or which have been subject to misuse, abuse,
misapplication, negligence, accident or which have had the serial numbers al-
tered, defaced, or removed. Accessories, including batteries and fuses, not of
our manufacture used with this product are not covered by this warranty.
To register a claim under the provisions of this warranty, return the instrument
or test equipment to Triplett Corporation, Service Department, One Triplett Drive,
Bluffton, Ohio 45817, transportation prepaid. Upon our inspection of the prod-
uct, we will advise you as to the disposition of your claim.
ALL WARRANTIES IMPLIED BY LAW ARE HEREBY LIMITED TO A PERIOD OF
ONE YEAR FROM DATE OF PURCHASE, AND THE PROVISIONS OF THE WAR-
RANTY ARE EXPRESSLY IN LIEU OF ANY OTHER WARRANTIES EXPRESSED
OR IMPLIED.
The purchaser agrees to assume all liability for any damages and bodily injury
which may result from the use or misuse of the product by the purchaser, his
employees, or others, and the remedies provided for in this warranty are ex-
pressly in lieu of any other liability Triplett Corporation may have, including
incidental or consequential damages.
Some states (USA ONLY) do not allow the exclusion or limitation of incidental
or consequential damages, so the above limitation or exclusion may not apply
to you. No representative of Triplett Corporation or any other person is autho-
rized to extend the liability of Triplett Corporation in connection with the sale of
its products beyond the terms hereof.
Triplett Corporation reserves the right to discontinue models at any time, or
change specifications, price or design, without notice and without incurring
any obligation.
This warranty gives you specific legal rights, and you may have other rights
which vary from state to state.
Fox
Checking Continuity:
The FOX can be used as a visual continuity indica-
tor. Set the FOX’s Function Switch to CONTINUITY/
TALK. When the FOX’s red and green alligator clips
are touched together, the LED will light, indicating
continuity. To check continuity, connect the red
and green alligator clips to the circuit under test
and observe the LED. Continuity from zero to 10K
ohms will be indicated by the brightness of the
LED. The LED will be bright at low resistances
and dim at high resistances.
NOTE: Do not attempt to measure continuity on a
powered line. Prolonged connection to a short cir-
cuit (zero Ohms) may damage the FOX.
Supplying Talk Power:
The FOX will supply power to operate handsets.
This feature is particularly useful when two install-
ers are working at terminal panels that have at least
one identified pair connected between them, but
are not yet connected to the CO battery. The FOX
allows the installers to communicate using their
handsets. Set the FOX’s Function Switch to
CONTINUITY/TALK and connect the handsets as
shown in Figure 2. The FOX’s LED will light when
supplying Talk Power.
NOTE: Some handsets may not operate properly
at the power level supplied by the FOX.
Using a Nicad Battery:
The FOX can recharge a 9 volt Nicad battery by
using CO power. To use this feature, simply re-
place the standard 9 volt battery with a 9 volt Nicad
battery. To charge the Nicad, set the FOX to OFF/
LINE POLARITY, and connect the alligator clips to
the line in Reversed Polarity (Red to positive and
Green to negative). Connecting to the line in Nor-
mal Polarity WILL NOT CHARGE the battery. Ap-
proximately 16 hours is required to fully charge a
typical Nicad battery (refer to battery manufacturer
specs).
Emergency Fast Charge:
The FOX’s circuitry incorporates a fast charge
mode. This mode is not recommended for casual
use because it exceeds the battery’s nominal
charge current and will shorten the battery’s life.
Charging current could be as high as 90 mA.
To use this feature, set the FOX to CONTINUITY/
TALK and connect the alligator clips to a powered
line in Reversed Polarity (Red to positive and Green
to negative). DO NOT charge the battery for more
than 30 minutes. Irreversible shortening of the
battery’s life may result. DO NOT connect to the
line in Normal Polarity. Damage to the battery may
result.
Ringing Current:
The FOX will signal the presence of ringing cur-
rent by flashing its LED. This indication is obtain-
able in either the OFF/LINE POLARITY or TONE
mode. Depending on the phone system, the LED
may indicate ringing current in either Normal or
Reversed Polarity. To perform this test, simply
connect the alligator clips or the modular plug to
the line to be tested. The FOX will not seize the
line on most phone systems.
BATTERY REPLACEMENT:
Remove the screw on the back of the case. Re-
move the case front. Replace the battery. Reas-
semble the case.
