Power Cap
®
Unit Tester
We strongly recommend that each customer obtain a Power Cap® unit tester.
At least once a month, check the receiver battery with the Power Cap® unit tester.
The Power Cap® unit tester measures the internal resistance of a Power Cap® unit and
shows how much life is left in the battery.
To test a Power Cap® unit with the Power Cap® unit tester, remove the Power Cap®
unit from the receiver and put it into the Power Cap® unit tester the same way that you
would put it into a Computer Collar® unit. If the battery is good, the green and red LEDs
on the tester will both light. If neither LED on the tester lights, or just the red LED lights
dimly, the Power Cap® unit needs to be replaced
Periodic Maintenance Checks
System Device How often What to look for
MaxDog ™ Computer Daily • Check Power Cap® Battery status light
Collar Unit • Review chart for status indicators (see page 5).
Signal Field Width Monthly and after a thunderstorm • Verify the signal field wire is
active throughout the property, see Monthly Signal Field Width Test below.
Monthly Signal Field Width Test
You should always be aware of your system’s signal field width. Check the width of the
signal field from only one place on the signal field loop wire. Always check the signal
field width from the same place. Take the MaxDog ™ Computer Collar® unit off your
pet to measure the signal field width.
1. Hold the Invisible Fence® Brand MaxDog ™ Computer Collar® unit so it is parallel
to the signal field wire.
2. Hold the collar so it is about the same height and at the same angle as it will be when
the pet is wearing it.
3. Walk slowly toward the signal field wire. The receiver will activate when you reach
the edge of the signal field. Do NOT touch the correction posts at this time!
If the receiver does not sound a warning tone where the edge of the signal is supposed to
be, immediately call your Invisible Fence® Brand Dealer for service. Use a leash (lead)
or other means to contain your pet until all necessary service has been completed.
