2 - Start Up
Both the FF310R and FF310T are factory supplied with batteries. To install the batteries
follow the steps below:
1. Open battery drawer at back of each unit ( factory supplied batteries
are disconnected).
2. Remove the battery, and connect it observing the polarity of the battery connector,
repeating the operation on both units.
3. Press the On/Off button on the FF310T (FaultFinder Transmitter), green LED will
start flashing. If green LED does not starts flashing, check the battery polarity and
reinstall if necessary. To turn the unit off, press the On/Off button again.
4. Press the On/Off button on the FF310R (FaultFinder Receiver), green LED will
turn on. If the green LED does not turn on, check the battery polarity and reinstall
if necessary. To turn the unit off press the On/Off button again.
3 - Switching On and Off the FF310 set
The FF310T
FaultFinder Transmitter is turned on and off by momentarily pressing the “ON/OFF”
button, and it must be turned off manually
after use by pressing the On/Off button. Before
storing the unit check to make sure that all lights are off, failure to do so will result in a
much shorter battery life.
The FF300R
FaultFinder Tracer can be turned on and off manually by momentarily pressing the “On/Off”
button, however after 3 minutes of not being used, it will turn off automatically to conserve
battery power. Turning the unit off manually will prolong battery life.
Low Battery indicator
From time to time the batteries on both units will need to be replaced. When the battery
is below the minimum operating voltage, upon turning the unit on (FF310T and FF310R)
both lights will flash for 1 second and the unit will turn off automatically. In this case replace
the batteries with a new set of 9 Volt alkaline batteries. To install the new batteries, follow
the instructions in the preceding section:
