the problem, change the orientation of the unit or
move it farther away from the source of interference.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the
vicinity of the unit. Such noise could occur when
receiving or initiating a call or while conversing.
Should you experience such problems, you should
relocate such wireless devices so they are at a
greater distance from this unit or switch them off.
• Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed
vehicle or otherwise subject it to temperature
extremes. Excessive heat can deform or discolour the
unit.
• When moved from one location to another where the
