Fort Worth, Texas 76102 OWNER’S MANUAL — Please read before using this equipment. www.radioshack.comSM 21-1930 21-1930 AO0148AAA1 04A03 Printed in China Thank you for purchasing the RadioShack Dual-Bay FAST Charger for GMRS/FRS 2-Way Radios. This charger works with these RadioShack GMRS/FRS radios: 21-1902, 21-1903, 21-1904, and 21-1905. Your dual-bay fast charger enables you to charge a pair of GMRS/FRS radios simultaneously. Rechargeable AA/AAA, Ni-Cd/Ni-MH batteries are fully charged in about 2 hours (50–120 minutes). FEATURES Charging indicators — the LED indicates the charging status. • Blinking Green: Charging • Green: Fully Charged • Red: Stand-by Automatic cut off — when batteries are fully charged, the charger stops automatically. A safety timer provides extra protection against overcharging. Over current protection — constant current charge in all charging stages. Auto current selection — automatically changes the charging current according to the capacity of the batteries resulting in quick and efficient charging. OPERATION 1. Insert the supplied adapter into the 12.8V power jack on the back of the charger. Then, plug the other end of the adapter into a standard AC outlet. Ô 2. Select one pair of the supplied adapters that corresponds with the FRS radio that you want to charge (21-1902/1903/ 1904/1905). Insert the adapter into the charging bay first, then insert the corresponding FRS radio into the charging bay. The green LED blinks to indicate that the batteries are charging. Ô You can use this charger to charge Ni- Cd and Ni-MH batteries of different capacities. The charging time depends on battery capacity. After the batteries are fully charged, the LED stops blinking and lights a steady green. The following chart lists estimated charge times.Ô CARE Keep the charger dry; if it gets wet, wipe it dry immediately. Use and store the charger only in normal temperature environments. Handle the charger carefully; do not drop it. Keep the charger away from dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new. SPECIFICATIONS Charging current ............................ 1200mA Max Charging time .......................... 50 – 120 minutes (AA/AAA Ni-Cd/Ni-MH 600 – 1800mAH) Safety timer ................................ 120 ± 2 minutes Dimensions (HWD) ......... 77/8 × 33/4 × 23/8 inches (200 × 95 × 60 mm) Weight .......................................................12.7oz (360g) Specifications are typical; individual units might vary. Specifications are subjected to change and improvement without notice. Charging Bays Adapters Ô NOTES Ô • Fully discharge Ni-Cd batteries before charging. Repeated partial discharging and recharging may shorten battery life. This does not apply to Ni-MH batteries. • It is normal for batteries to become warm while charging. • If the LED changes to RED after several seconds, the radio may not be inserted firmly. • For batteries with a capacity of less than 600mA, the charging time may be less than 50 minutes and the batteries can be warmer (than batteries with a capacity greater than 600mA) during charging. • Use only the supplied adapter. Use of other adapters may damage your charger. • If dead batteries, non-rechargeable batteries, or batteries installed in the wrong direction are detected, the LED changes to red and stops charging. When charging two radios, if one of the radios is turned on, both radios enter the slow charging mode and may not be fully charged after hours of charging. For the fastest charge, turn both radios off. • Never attempt to charge any batteries other than Ni-Cd or Ni-MH rechargeable batteries. • Only charge batteries of the same type and capacity. Do not mix new and old batteries or batteries of different types or capacities. • Charge batteries in a location that is between 50°F and 86°F (10°C and 30°C). If the location is too cold, the batteries cannot be fully charged. If the location is too warm, the batteries may be damaged permanently and lose their ability to charge.
