PLEASE READ THE INFORMATION AND FOLLOW ALL INSTRUCTIONS THOROUGHLY BEFORE 

USING THIS PRODUCT.

       

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.

Caution:

Charge 

only NiMH type batteries

 on this charger.

Do Not

 mix AA and AAA or different capacity batteries together when charging

Use only R2G, NoMEM PRO or other proper NiMH compatible chargers to recharge 

the batteries included.

Batteries may leak or explode causing personal injury if inserted improperly, disposed 

of in fire, mixed with other battery types, or short circuited.

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.

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.

Bad Cell Detection

When charge process is started, the charger detects the health status of each of the cells in 

the battery compartment. If any batteries are unsuitable for charging, i.e. short circuit or 

reversed polarity, the word “BAD” will emerge on the LCD screen and the battery icon will 

flash.

USB Charge Port Operation

When using the USB PowerPort on this charger, the AA/AAA charger function has priority. 

The USB PowerPort will not be available while batteries are installed and charging. Once the 

AA/AAA batteries have completed their charge, the USB port will be turned on automatically. 

The “USB symbol” will be shown on the LCD screen to indicate the USB socket is ready for 

use.

Note: 

Make sure the maximum loading is not exceeding 500mA for the USB socket. Do not 

attempt to overload the USB port or damage to the charger or USB device may result. USB 

output port is not available when the unit is being powered from USB.

Clock / Alarm / Day-Date operation

The following shows which buttons on the setting panel you need to press to navigate 

between modes. The 2 feet on the bottom rear of the chassis act as switches to activate the 

blue backlight on the LCD display. In any mode, just to hit the top of the unit lightly and the 

black light will light on for about 10 seconds. The backlight will only operate while the unit is 

plugged into power using any of the supplied power adapters.

In the regular Time mode, press the B button once and the “Time” icon will starts to flash on 

the LCD screen along with the item to be changed, which indicates Time Setting mode. Use 

the C and D buttons to change the value of the flashing item. Once the flashing item is set to 

what you want, press B to select the next setting and change as listed above. The Year can
