Motorola L3392, L3391 owner manual Safe Usage Notification

"SAFE USAGE NOTIFICATION:

For reasons of personal safety and optimal radio performance, Motorola has designed the ML850 with an intended purpose and position of use either in a secured vehicle docking station or on the top of an office desk. Motorola strongly recommends using this product in a vehicle only when it is physically-secured in a locked or assured-stationary location as failure to do so may cause the product to cause harm in accidents or other conditions. Similarly, Motorola strongly recommends that the unit not be situated for a prolonged period in an a position that places the antennas directly against the human body (for example, by 'tucking' an operational, radio-equipped unit under one's arm).

NOTE: The radio modems in the ML850 may continue to transmit and receive signals even while the laptop is in a closed position. Failure to follow any part of this notification could cause degraded radio performance or harm to the user".
