MORE MOBILE QUESTIONS
I drive a company car and I would like to
have a full car kit for my Nokia 2110, but the boss wonít allow me to have any holes
drilled in the dashboard. I could probably get away with using one of those
air-vent mounted cradles and a power
cord (the car is a P-reg Ford Mondeo), but I donít think that would be very
satisfactory. Can you think of any way of fitting a car kit, without making any
Sara Levington, Doncaster
All of the full-spec car kits weíre aware of require
some holes to be drilled, but a skilled installer can minimise their impact,
and may even be able to make sure theyíll remain out of sight, when the kit is
removed. Maybe you could persuade your employer to talk to a couple of local
firms, for reassurance. If he wonít see reason then youíre only alternative is
one of the Ďsimpleí hands-free kits, like those made by Ora and Vivox. In both outfits
the speaker is built into the power adaptor, that fits into the cigarette
lighter plug. Youíll have to use it with a vent-mount cradle, or an Easy Mount
bracket, designed specifically for your make of car, which fits onto existing
fittings on the dashboard.
DO NOT USE IN THE STATION
I have noticed that several petrol stations in
my area now have notices saying that mobile telephones must not be used on the premises.
Why is that?
James. T. Rodd, Ilford
Thereís a couple of reasons. The first is
that radio transmitters can, in theory at least, generate or induce sparks in
nearby metallic objects. Clearly that would be a bad thing if it happened
inside a tank containing several thousand gallons of four-star. We have to say
that it is extremely unlikely that a hand-held cellphone, which has an output
power of just a few milliwatts, could do such a thing. Nevertheless, itís
possible that higher-power transmitters, including proper carphones, mobile
radios used by emergency services, taxi radios and CBs could pose a threat.
The other reason why garage owners donít like
radios transmitters being used on their forecourts, is that the signals can
affect the sensitive electronic microcircuits inside their pumps. It may be one
of those urban myths, but there are stories of pumps going haywire when someone
is using a phone nearby, dispensing tank-fulls of fuel, with the display just
showing a few pence. It could just as easily go the other way though, and charge
you ten quid a litre, so itís sensible to obey the rules!
Six months ago I had an Ericsson hands-free
car kit installed in my car, which is a rather smooth Volkswagen Golf Gti. Since
then I have noticed that several of my tapes, including oneís by the Spice Girls,
Take That and Snoop Doggy Dog have started to sound really hissy. Is there any
way the phone could be wiping them?
Alistair Creely, Knutsford
If itís only affecting those three tapes then
Iím tempted to say that it must be a design feature, that we commend to anyone
with any sort of musical taste. But seriously, itís highly improbably that the
phone itself is responsible, it doesnít generate any magnetic fields, at least
none that would strong enough to wipe a tape cassette. The most likely suspect
is the car kitís speaker, if its anywhere near where you store your tapes. Otherwise
check around for other sources of magnetism, maybe youíve had some new car stereo
speakers installed lately? Powerful amplifiers can generate magnetic fields?
Makes sure you keep your tapes in a purpose designed box, avoiding places that
may experience extremes of temperature, out of direct sunlight and away form
sources of vibration.
