The Battery Threshold screen allows you to preset a voltage. When
the battery voltage in your vehicle drops below the preset voltage, the
vibration alarm in the handheld unit will activate. Typical recommended
preset values are 1.1 volts per cell, however, when using high current
draw servos it may be necessary reduce that value to .9 volts per cell.
Recommended voltage settings:
• 5-cell 6.0 volt pack = 6.6 volts
• 4-cell 4.8 volt pack = 4.4 volts
To access the Battery Threshold function press the  button
until Batt Threshold appears on the screen. Press the + or-
button to increase or decrease the battery voltage value.
Note: The Battery Threshold screen is only available
when the vibration function is enabled. (See above)

The Temperature Threshold screen allows you to preset a do not
exceed temperature value. When the engine temperature in your
vehicle exceeds this preset temperature, the vibration alarm in the
handheld unit activates warning of an over-lean condition. Each type
of vehicle will require it is own maximum temperature value. It is best
to determine this by finding the optimum operating temperature and
then setting the maximum temperature range 15°F to 20°F higher.
To access the Temperature Threshold function, press the  button
until Temp Threshold appears on the screen. Press the + or-
button to increase or decrease the temperature threshold value.
Note: The Temperature Threshold screen is only available
when the vibration function is enabled. (See above)
