high impedance. The manufacturer suggests leaving the unit charging
for a period of 40 hours using the built-in AC charger before use.
Charging/Recharging Using the
Built-In 120 Volt AC Charger and
AC Extension Cord (not supplied)
1. Lift the protective cover of the built-in 120 Volt AC Charger
located on the back of the unit (refer to Fig. 1 to locate). Connect
an extension cord to the unit. Plug the other end of the cord into
a standard 120-volt AC wall outlet. When the unit is properly
connected to an AC power source, the LCD screen will display
the following:
The bars on the Battery Status Icon represent the charge level of
the unit's internal battery. The bars on the Battery Status Icon will
change from empty to solid (bottom to top) repeatedly to indicate
the unit is charging. The backlight will turn on for 10 seconds (only).
2. Charge for approximately 40 hours or until the Battery Status Icon
shows 4 solid bars.
3. When charging is complete, unplug the AC extension cord from
the AC outlet and then disconnect it from the unit.
Charging the Unit Using the 12V DC
Charging Adapter
CAUTION – To reduce the risk of property damage:
• NEVER connect this unit to a positive grounded vehicle using the 12
Volt DC Charging Adapter.
• The 12 Volt DC Charging Adapter must only be connected to batteries
with a nominal output voltage of 12 volts. The unit will not operate
from a 6 volt battery and will sustain permanent damage if connected
to a 24 volt battery.
PROCEDURE
1. Lift the protective cover of the Built-in 120 Volt AC Charger located
on the back of the unit (refer to Fig. 1 to locate). Make sure the
AC extension cord is disconnected from the 120 Volt AC Charger.

DC Charging Port on the back of the unit.
3. Insert the grooved tip of the 12V DC Charging Adapter into the
vehicle's 12V DC accessory outlet or other functioning 12V DC
power source. When the unit is properly connected to an DC power
source, the LCD Screen will display the following:
The bars on the Battery Icon represent the charge level of the
unit's internal battery. The bars on the Battery Icon will change from
empty to solid (from bottom to top) repeatedly to indicate that the
unit is charging. The backlight will turn on for 10 seconds (only).
4. Charge for 6 hours. Do not overcharge.
5. Disconnect the DC Charging Adapter from the unit and the 12V
DC power source when not in use.
Notes Concerning the DC Charging Method:
A. IMPORTANT: The DC recharging method will NOT recharge the
unit as effectively as recharging from 120 volt AC. Manufacturer
suggests that you only use the 12 Volt DC Charging Adapter if
