case front. Install / replace the battery. Reassemble the
case.
7.1.3: Using a rechargeable battery in the FOX
The FOX can recharge a 9 volt Nicad battery by using tele-
phone Loop Current (CO power). To use this feature, simply
replace the standard 9 volt battery with a 9 volt Nicad bat-
tery. To charge the Nicad, set the FOX to OFF/LINE POLAR-
ITY, and connect the alligator clips to the line in Reversed
Polarity (Red to positive and Green to negative). Connect-
ing to the line in Normal Polarity WILL NOT CHARGE the
battery. Approximately 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
