Introduction

Thank you for purchasing the R2G802U 2 Hour Charger. Read the instruction manual
thoroughly before use and keep the manual for later reference. This manual contains
important operating instructions for your R2G Rechargeable Battery System. The
R2G802U combines a Travel Alarm Clock, 2 hour microprocessor controlled charger for
1 to 4 AA/AAA NiMH batteries, thermometer, and USB PowerPort for charging your cell
phones, MP3 players, or any other device that accepts power from a USB port. All the
functions are displayed clearly on a large backlit LCD Display. The charger can be
powered 3 ways and includes a high efficiency “switching” type power supply that
automatically adjusts to any voltage from 100 – 240VAC, for international use. Also
included are a cord for using the charger in the car, and a USB cable for powering the
charger from your computer.

Before Use

To activate the clock and thermometer functions, pull out the tab from the side of the
casing at the access cover to the clock battery on the bottom of the unit. The clock
portion of the LCD display will turn on and you will hear alarm music for 10 seconds. The
Clock / Alarm is now ready for use and should be set to the proper time / date. If the LCD
display gets dim or the sound of the alarm tone become weak, replace the clock battery

with another new “CR-2025” type 3V Lithium battery which is located on the bottom side

of the charger base.

Charging Instructions

1. Choose the source of power for the charger unit. You can use either the AC adapter
which is international capable accepting 100-240VAC (plug adapter may be required in
other countries, not included), or the DC car cord while on the move or plugged into a
USB port on your computer (charge times are increased when USB power is used).
Simply plug the desired power cable into the side of the charger unit and the other end
into the appropriate power source.

2. Insert 1 to 4 AA or AAA rechargeable
Ni-MH batteries into any open battery
location observing the proper battery
polarity to the marks in the battery
compartment. Do not mix AA and AAA
batteries while charging. The Blue
backlight will light up for around 10
seconds once the batteries are inserted
correctly. For charging AA batteries, pull
up the adjustable battery contact plate
before inserting the AA batteries into the
compartment. To charge AAA batteries,
push it back down. The charger
automatically adjusts the charging
current depending on the size of the
battery being charged.

3. The LCD screen will indicate the proper charging and the word “Charge” will be shown
to the left of the battery symbols that indicate each battery’s charge progress. After the
batteries are fully charged, the word “FULL” will appear on the LCD screen to indicate
the trickle charge and the charged batteries are ready for use. Once charge is complete,
remove batteries and unplug the charger as soon as it is practical. Do not leave batteries
in charger for extended periods of time (more than 1-2 days) or when the charger is not
plugged in. Unplug the charger when not in use.

4. Begin again at Step-1 to charge the next set of batteries.
