1.1 Disclaimers 
RF Burns can occur if the output terminals or antenna wire of the SG-
237 are touched while transmitting. Use caution to avoid injury and 
burns. 
Prolonged exposure to RF should be avoided. Those persons using 
heart pacemaker devices should avoid RF exposure. 
To avoid injury and damage to equipment: Whenever possible, we 
strongly recommend reducing transmit power. Preferably, 10 to 25 
watts should be used and will generally provide good communica-
tions. If using an outside antenna, 100 watts can be used without any 
harmful consequences. 
If for any reason a particular setup or frequency does not provide the 
expected results, minor changes can significantly improve perform-
ance. For example: move the radio as far away as possible from the 
coupler or antenna; avoid coiled power or coaxial feed cables; recon-
figure setup, etc.
