Yamaha HTR-5990 Guia Do Utilizador

■ Installing batteries

• Change all of the batteries if you notice conditions such as the 

operation range of the remote control decreases, the indicator 
does not flash, or its light or display window become dim.

• Do not use old batteries together with new ones.
• Do not use different types of batteries (such as alkaline and 

manganese batteries) together. Read the packaging carefully as 
these different types of batteries may have the same shape and 
color.

• If the batteries have leaked, dispose of them immediately. Avoid 

touching the leaked material or letting it come into contact with 
clothing, etc. Clean the battery compartment thoroughly before 
installing new batteries.

• Do not throw away batteries with general house waste; dispose 

of them correctly in accordance with your local regulations.

■ Using the remote control
The remote control transmits a directional infrared ray. 
Be sure to aim the remote control directly at the remote 
control sensor on the main unit during operation.

• Do not spill water or other liquids on the remote control.
• Do not drop the remote control.
• Do not leave or store the remote control in the following types 

of conditions:
– places of high humidity, such as near a bath
– places of high temperatures, such as near a heater or stove
– extremely low temperatures
– dusty places

If the remote control is without batteries for more than 
2 minutes, or if exhausted batteries remain in the 
remote control, the contents of the memory may be 
cleared. When the memory is cleared, insert new 
batteries, set up the remote control code and program 
any acquired functions that may have been cleared.
