142 S1. Important Safety Information
Phone Operation
When placing or receiving a phone call, hold your radio 
product as you would a wireline telephone. Speak directly into 
the microphone.
Two-way Radio Operation
Your radio product has been designed and tested to comply 
with national and international standards and guidelines 
regarding human exposure to RF electromagnetic energy, 
when operated in the two-way mode (at the face, or at the 
abdomen when using an audio accessory) at usage factors of 
up to 50% talk/50% listen.
Transmit no more than the rated duty factor of 50% of the time. 
To transmit (talk), push the 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 
only when transmitting (in terms of measuring for standards 
compliance).
When using your radio product as a traditional 
two-way radio, hold the radio product in a 
vertical position with the microphone one to 
two inches (2.5 to 5 cm) away from the lips.
If you wear a radio product on your body when 
transmitting, always place the radio product in 
a Motorola approved clip, holder, holster, case 
or body harness. If you do not use a body-worn accessory 
supplied or approved by Motorola and are not using the radio 
product in the intended use positions along side the head in 
the phone mode or in front of the face in the two-way radio 
mode, or if you hang your device from a lanyard around your 
neck, keep the device at least 2.5 centimeters (1 inch) from 
your body when transmitting.

Turning Off Your Phone Before Flying
Turn off your phone before boarding any aircraft. To prevent 
possible interference with aircraft systems, the U.S. Federal 
Aviation Administration (FAA) regulations require you to have 
permission from a crew member to use your phone while  
the plane is on the ground. To prevent any risk of interference, 
FCC regulations prohibit using your phone while the plane is in 
the air.
Turning Off Your Phone in Dangerous Areas
To avoid interfering with blasting operations, turn your phone 
off when in a blasting area or in other areas with signs 
indicating two-way radios should be turned off. Construction 
crews often use remote-control RF devices to set off explosives.
Turn your phone off when you’re in any area that has a 
potentially explosive atmosphere. Although it’s rare, your phone 
and accessories could generate sparks. Sparks can cause an 
explosion or fire, resulting in bodily injury or even death. These 
areas are often, but not always, clearly marked. They include:
䡲 Fueling areas such as gas stations.
䡲 Below deck on boats.
䡲 Fuel or chemical transfer or storage facilities.
