OPERATING FEATURES

Your unit includes an array of operating features designed to increase usability and simplify user
interface. Please refer to the Parts and Controls diagram on page 3 to familiarize yourself with
the indicators and keypad controls as you proceed through this section.
A proper understanding of each key and its function will enhance your experience with this prod-
uct and allow you to get the most from its capabilities.

Constant Power Indication

The Constant Power indicator allows the user to see the battery level at all times.
The first LED (closest to the keypad) in the display is an 'intelligent' battery status indicator and
will remain on whenever the unit is powered on. The LED will illuminate in one of three colors to
indicate the battery voltage level.
If the LED is green, this indicates that the batteries are fully charged or have sufficient voltage
for normal operation.
If the LED is orange this is an indication that the batteries have enough voltage to operate but,
should be re-charged when the current usage of the unit is complete.
If the LED is red, the batteries should be immediately re-charged to prevent erratic performance
and/or failure of the unit during operation.

True Battery Voltage Indicator

The unit also includes a feature that will allow you to display and see the actual battery voltage
at any time.
To activate the True Battery Voltage test, press and hold the key for at least one second (do
not release the key during the one second period or the unit will shut off). The display will show
1 to 6 LED's in red, orange, and green to indicate the actual battery voltage as follows:
• 1 red = less than 4.4 volts RECHARGE THE UNIT IMMEDIATELY
• 1 red, 1 orange = 4.4 to 4.6 volts
• 1 red, 1 orange, 1 green = 4.6 to 4.8 volts
• 1 red, 1 orange, 2 green = 4.8 to 5.0 volts
• 1 red, 1 orange, 3 green = 5.0 to 5.2 volts
• 1 red, 1 orange, 4 green = greater than 5.2 volts. Fully charged
