. VI.FAQ(Frequently asked questions)
6.1 While mobile phone signal isolator is in operation,why there is
still signal indication on some mobile phones?
Reply:thisis only a feint.In fact,the mobile phones can not
communicate at the moment.With a casual press on the dial keys,it
will be found out that there is no signal indication at all.
6.2 Does the mobile phone signal isolator interfere with the normal
operation of other electronic devices
Reply:No,this is because the electromagnetic signal emitted by the
isolator is completely in the range of the mobile phone frequency
set by the state.It can only block off the communication of mobile
phones.In addition,this kind of signal is always in acomparatively
static state,it will not affect other electronic devices.
6.3 Does the mobile phone signal isolator do harm to human bodies
and mobile phones?
Reply:Please set your heart at rest.The electromagnetic signal
emitted by the isolator is very weak,it is shown by test data that
such signal will not do harm to human bodies.At th same time,the
mobile phone signal isolator will only block off the forwarding
signals of mobile phones,make it unable to communicat with the base
station,thus will not cause any damage to the Mobile phone itself.
6.4 Is there any difference of operation range between indoor use
and outdoor use?
Reply:Yes,the operation range usually refers to indoor range.When
using th device ina wide outdoor space,the operation range can
reach as long as hundreds of meters.It should be pointed
out.Whenever using it indoor,the operation range has some thing to
do with the conditions on the spot such as the distance from base
station to the devic and the installation place etc. therefore,
this point should be taken into account while using the isolator in
order to avoid any dead corner which will affect its aperation.
6.5 Is the effect of the isolator on GSMphone andCDNA phone the
Reply: it is a good question,the anti-disturbance performance of
CDMA phones is far better than GSMphones.However,there is not a
great difference,only about 2-4 meters although the operation range
of the isolator on CDMAphones is smaller than that on GSM.Yet,to
ensure good effect on CDMA phones,user should increase the number
of isolators indoors if necessary.
6.6 The housing of isolator gets hot after a period time of
operation,does long time operation destrous the device?
Reply:thank you for your carefulness.this is a normal phenomenon.In
fact,when designing,we take advantage of the heat conductivity of
legging casing made of aluminum alloy to assist radiating for long
time of stable operation.So,a hot casing will not damage the
