TECHNICAL DATA
CAUTION: The given range concerns open area - an ideal condition without any
natural or artificial obstacles. If there are some obstacles between a transmitter
and a receiver, it is advisable to decrease the range according to: wood and plas-
ter: from 5 to 20 %, bricks: from 10 to 40 %, reinforced concrete: from 40 to 80 %,
metal: from 90 to 100% , glass: from 10 to 20 %, Over- and underground medium
and high electrical power lines, radio and television transmitters, GSM transmit-
ters set close to a device system have also a negative influence on the range.
