Olympus WS-801 Introduction Manual

 Read the following descriptions carefully 
before using the Ni-MH rechargeable 
battery. 

 The rechargeable battery self-discharges 
while not in use. Be sure to charge it fully 
before use. 

 The rechargeable battery is a chemical 
product. The efficiency of the rechargeable 
battery may fluctuate even when 
the battery is operating within the 
recommended temperature range. This is an 
inherent nature of such products. 

  When operating the recorder:  
  

0°C - 42°C/ 32°F - 107.6°F 

  Charging:  
  

5°C - 35°C/ 41°F - 95°F 

  Storage for a long period:  
  

–20°C - 30°C/ –4°F - 86°F 

 Using the rechargeable battery outside 
the above temperature range may result in 
declining efficiency and a shorter battery 
life. In order to prevent battery leakage or 
rust, remove the rechargeable battery from 
the recorder when you will not be using it 
for a long time, and store it separately. 

 •  This recorder is designed to fully charge 

the battery regardless of its energy level. 
However, for best results when charging 
a newly purchased rechargeable battery 
or a battery that has not been used for 
a long time (more than one month), it 
is recommended to repeat the process 
of fully charging the battery and then 
letting it discharge 2 to 3 times. 

 •  Use the dedicated USB cable. If any other 

company’s cable is used, it may lead to 
malfunction of the recorder. Also, never 
use this dedicated cable with any other 
company’s products. 

 •  If you would like to charge the recorder 

using the [  Composite  ]  setting,  select 
[  Optional  ] in the USB connection 
settings, then connect the recorder to a 
PC. Selecting [  AC  Adapter  ] in the 
[  USB  Connection  ] display will enable you 
to charge the recorder (
