Motorola SL7550 用户手册

Transmit no more than the rated duty factor of 50% of the 
time. To transmit (talk), push the Push-To-Talk (PTT) button. 

To receive calls, release the PTT button. Transmitting 50% of 

the time, or less, is important because this radio generates 

measurable RF energy exposure only when transmitting (in 

terms of measuring for standards compliance).

To protect your hearing, use the lowest volume necessary to 
do your job, turn down the volume before adding a headset or 

earpiece, and limit the amount of time you use headsets or 

earpieces at high volume.

User awareness instructions should accompany device when 
transferred to other users.

NOTE: For more details please read the information about RF 

Energy Exposure Awareness and Control Information 
and Operational Instructions for Occupational Use in 
the Quick Reference Guide/Safety Booklet (Motorola 
Publications number 68009553001) provided with your 
radio.
