The ER102 can be powered by the following methods:
1. Built in Rechargeable Battery Pack: The included rechargeable battery pack is
located in the battery compartment and is charged by cranking the dynamo rapidly or by
the AC adapter. It is specified as 3.6 VDC, 650 mAh, nickel metal-hydride (Ni-MH).
1. Only use our Ni-MH battery pack.
2. Do not attempt to charge alkaline batteries or any battery packs other than
the ones indicated in this manual. This could cause leakage and damage to the
radio.
2. AC Adapter: It is suggested that before the radio is used, the internal rechargeable
battery pack be charged with the AC adapter for a minimum of 12 hours. This way, the
radio will have maximum performance time. To charge with the AC adapter, ensure the
power source switch is in the “AC/Dynamo” positon. Then, insert the adapter in an electrical
outlet and the plug into the jack on the backside of the radio labeled DC IN6V. The red LED
light below the LCD will be lit to indicate the unit is charging.
For recharging after use with a depleted battery pack, it will take about 12 hours to
recharge if using the AC adapter.
3. Dynamo Power: Turning the dynamo crank charges the built-in Ni-MH battery pack.
It can be charged with the ER102 power source switch turned to the “AC/Dynamo” position.
While charging, the red LED charging light will be on (located on the front of the unit below
the LCD). Play time depends on a variety of factors, such as rapidity of cranking, length of
time cranked and the audio volume at which the radio is played.
1. Switch the power selector to the “AC/Dynamo” position.
2. Turn the dynamo-crank vigorously either clockwise or counterclockwise
for a comfortable period of time.
3. To turn the radio on, switch the AM/FM/WX dial to desired function. Then ensure
the volume is at an audible level.
4. Alkaline Battery Operation: The ER102 is designed to operate on three AA batteries
(not included). Install the batteries by removing the battery compartment cover and match-
ing the polarity. To play the ER102 on its AA batteries, turn the radio on by setting the
power source switch to the “Alkaline” position.
Note: When an AC adapter is in use, please slide the switch to AC/Dynamo. However, for
long term storage, we recommend removing the AA batteries to prevent leakage.
