Signal Strength
The signal strength --
defined as the difference, or delta (Δ), between the magnetic field
detected at the top and bottom sensors -- is indicated by the frequency of the audio signal. A
higher audio frequency tone indicates a stronger signal; a lower audio frequency tone
indicates a weaker signal.
Battery Level
When the battery level gets to be too low (6.8 V), the unit starts to beep for approximately ½
second, every 13 seconds, to remind the user that the battery needs to be replaced. When
you hear this tone, replace the battery as soon as possible. Battery life varies with usage and
ambient temperature. Cold temperatures reduce battery life. When the battery level reaches
6.0 V, the unit turns off to protect the electronic circuits inside.
Replacing the Battery
SPOT is powered by one 9-volt disposable battery. The battery compartment is located near
the top of the locator, as shown in Figure 3. To remove the battery, simply unscrew the two
flat head screws holding the battery door. The screws are captive and will not come off the
battery door. Once you have removed the battery door, gently pull the battery from its
compartment and unplug the connector.
Connect a new battery, place it back in the compartment, and replace and screw in the
battery door. As a safety measure, the unit will not turn on if the battery connector is not
inserted correctly. You should never have to force the battery door closed. If the battery does
not sit easily and flat in place, check the battery and the connector for proper seating in the
battery compartment.
