INTRODUCTION
The Dynamo is a handheld, multi-function eco-tool that operates without 
the need for replacing batteries. It combines an LED flashlight, an AM/ 
FM radio, an emergency siren, an earphone jack and a cell phone 
charger all in one handy unit.
The Dynamo doesn’t need an external power source: It’s powered 
simply by winding the built-in generator to recharge the internal battery.
The easy-to-follow instructions in this manual help make use of The 
Dynamo quick and simple, so you’ll soon be enjoying the benefits of 
these additional features:
•  Lightweight design for convenient transport
•  Durable plastic case for practical use under most conditions
•  Attached wrist strap for hand carrying or handy belt or pack-strap 
  attachment
•  Protective storage pouch
•  Thumb and fingertip grips for secure handling
•  Foldaway winder and flush-set buttons that minimize the risk of  
  damage due to use under rugged conditions

OPERATION
CAUTION:
•  Do not expose The Dynamo to direct sunlight for a long period of  
  time, and keep it away from fire and excessive heat.
•  This product is not waterproof.
•  Only use a moist cloth to clean The Dynamo’s case and lens. No 
  other cleaner or solvent is recommended.
•  Avoid pointing the flashlight directly at the eyes.
Charging a Cell Phone Using The Dynamo
1. Unfold the flip-down crank handle  
  and wind The Dynamo’s built-in  
  generator one full minute (130  
  rev/min.). 
2. When the Charging Indicator light comes  
  on, wind for one additional minute. 
3. Plug the charging cord into the D/C Out jack on  
  The Dynamo, then connect the other end of the cord to the cell  
  phone. The Dynamo can provide up to 2 minutes of talk time with the 
  cable connected, and the phone can also be re-charged during calls.
Charging The Dynamo for Non-Cell-Phone Use
1. Unfold the flip-down crank handle  
  and wind The Dynamo’s  
  built-in generator. For  
  every minute of winding,  
  the built-in generator can 
  support the flashlight for  
  30 minutes and the radio   
  for approximately 15 minutes   
  (depending on the volume  
  level).
