CAUTIONS: 

1. 

The charger is restricted to

 charging NiCd and NiMH rechargeable batteries only. 

Never use this charger for other types of batteries such as alkaline, lithium, carbon zinc 
or other types that are not specified. 

2. 

The charging unit should only be used at normal indoor room conditions. 

3. 

Place charger on a hard flat surface. 

4. 

Always follow the charging instructions for the rechargeable battery. Observe the 
recommended charging current of the rechargeable batteries. Never use a charging 
current higher than recommended in the charging process. 

5. 

Never use any power cable and transformer other than those originally supplied with the 
charging unit. 

6. 

The rechargeable batteries may become hot during charging (especially when a high 
charging current is chosen). User should take extra care when taking out the batteries 
after charging.    

7. 

Unplug the charging unit from the power source when not in use.
