Important Safety Precautions 

 

The JL20 unit is powered by 12VDC. Only personnel who have received 
relevant training from Juni are authorised to open any part or section of the 
JL20. To prevent electrical shock when installing or maintaining the equipment, 

ensure the supply of VDC (and/or VAC) is removed

 by switching off the 

power from the power source before accessing any section of the equipment. 
 
 
 

Only when the Repeater is fully installed and all cable connections are made 
should the power be turned on. Ensure all installation items are complete 
before turning on the Repeater. 

on. 

 
 
 

Ensure the total input power to the Repeater is within the range -75dBm ~ -
30dBm. Input powers outside this range may affect Repeater performance. 

 
 

Ensure frequencies are configured correctly. Incorrect frequency settings can 
severely affect Repeater performance. 

 
 

When installing the Repeater, ensure the heat-sink section of the Repeater is 
not exposed to direct sunlight. Where possible, have the heat-sink section of 
the Repeater facing a northerly directi

 
 

Always observe the warning labels and markings present on the equipment. If 
unsure, contact Juni America on +1 800 216 0466 for advice. 

 
 

The JL20 can weigh up to 5kg. Ensure the correct procedures are used in 
moving or lifting the equipment to avoid injury.
