This unit includes 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 indi cators and keypad controls as you proceed through this section.
Constant Power Indication
The Constant Power indicator allows the user to see the battery level at all times.
The first LED in the display (leftmost) is an “intelligent” battery status indicator and
remains 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, the batteries are fully charged or have sufficient voltage for
normal operation.
If the LED is orange, the batteries have enough voltage to operate, but should be
recharged when the current usage of the unit is complete.
If the LED is red, the batteries should be immediately recharged to prevent erratic
performance and / or failure of the unit during operation.
True Battery Voltage Indicator
The unit also includes a feature that allows you to display and see the actual battery
voltage at any time.
To activate the True Battery Voltage test,
1. Press and release the ON/OFF key to turn the unit ON.
2. Then press and hold the ON/OFF key.
3. The display will show 1 to 6 LEDs 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
