SAFETY PRECAUTIONS

 

 
This equipment is intended for general laboratory use in a wide variety of industrial and 
scientific applications and designed to be used in the process of generating, controlling 
and measuring high levels of electromagnetic Radio Frequency (RF) energy. It is the 
responsibility of the user to assure that the device is operated in a location which will 
control the radiated energy such that it will not cause injury and will not violate regulatory 
levels of electromagnetic interference. To reduce the risk of fire, electric shock and/or 
injury to persons, basic safety precautions should always be followed when using 
electrical devices, including the following: 
 

1. 

READ ALL INSTRUCTIONS BEFORE OPERATING THE ACTIVE MONOPOLE 
ANTENNA.

 

 

2. 

Use the antenna only as specified.

 

 

3. 

Please dispose of batteries responsibly and in accordance with all applicable laws 
and regulations. 

 

4. 

To protect against electric shock, do not immerse the power cord, power plug or 
Antenna in water or in any other liquid.

 

 

5. 

Do not operate the product with a damaged charger cord or charger plug or after 
the antenna malfunctions or has been damaged in any manner.

 

 

6. 

This is not intended for permanent outdoor use.

 

 

7. 

Do not allow the cord or the antenna to rest on or near hot surfaces such as a hot 
gas or electric burner or a heated oven.

 

 

8. 

Disconnect the charger from the active monopole when not in use and before user 
servicing and cleaning.

 

 

9. 

Do not use this product for anything other than its intended use. 

 
 

RANGE OF ENVIRONMENTAL CONDITIONS 

 
This equipment is designed to be safe under the following environmental conditions: 

 
Indoor use 

 

Altitude: up to 2 km 

 

Temperature:  5

 C to 40

 C 

 

Maximum relative humidity: 80% for temperatures up to 31

 C. 

Decreasing linearly to 50% at 40

 C 

 

Pollution degree 2: Normally non-conductive with occasional 
condensation. 
 

While the equipment will not cause hazardous condition over this environmental range, 
performance may vary.
