 Compliance with RF Energy Exposure Standards 

Your   wireless telephone is designed and tested to comply with a number of national 
and international standards and guidelines (listed below) regarding human exposure to 
radio frequency electromagnetic energy. This radio complies with the IEEE (FCC) and 
ICNIRP exposure limits for occupational/controlled RF exposure environment at duty 
cycles of up to 50% talk-50% listen and should be used for occupational use only. In terms 
of measuring RF energy for compliance with the FCC exposure guidelines, your radio 
radiates measurable RF energy only while it is transmitting (during talking), not when it is 
receiving (listening) or in standby mode. 

 The approved batteries supplied with this radio are rated for a 5-5-90 duty cycle (5% 

talk-5% listen-90% standby), even though this radio complies with the FCC 
occupational RF exposure limits at duty cycles of up to 50% talk. 

wireless telephone complies with the following of RF energy
