6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the 

manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat

9. Only use attachments/accessories specified by the manufacturer.
10. Use only with the cart, stand, tripod, bracket, or table specified by 

the manufacturer, or sold with the apparatus. When a cart is used, 
use caution when moving the cart/apparatus combination to avoid 
injury from tip-over.

11. Unplug this apparatus during lightning storms or when unused for 

long periods of time.

12. Refer all servicing to qualified service personnel. Servicing is 

required when the apparatus has been damaged in any way, such 
as power-supply cord or plug is damaged, liquid has been spilled or 
objects have fallen into the apparatus, the apparatus has been 
exposed to rain or moisture, does not operate normally, or has been 
dropped.

13. 

WARNING:

 To reduce the risk of fire or electric shock, do not 

expose this product to rain or moisture.

SAFETY NOTES

Excessive sound levels can cause permanent hearing damage.

1. Always adjust the volume to the lowest level before listening to 

unknown transmissions.

2. Use the lowest reasonable level consistent with hearing safety.
3. Do not use high sound levels in the earphone to overcome high 

ambient sound levels.  That is absolutely foolish!  Demand and use 
high isolation earphones.

4. Do not expose your ears to sound levels that cause them to ring.  If 

your ears do ring after exposure, think of it as a warning bell telling 
you not to do that again.

Please read and follow these 

instructions before operating 

this product.
