Operating environment
Make sure that no special regulation is in
force that imposes restrictions on the use of
mobiles. Restrictions to mobiles would also
apply to the DTM.
Electronic devices
Most modern electronic equipment is shielded
from radio frequency (RF) signals. However,
certain electronic equipment may not be
shielded against the RF signals from your DTM.
Pacemakers
Pacemaker manufacturers recommend that a
minimum separation of 20 cm (6 inches) be
maintained between a hand-held wireless
phone and a pacemaker. The same restriction
should apply to the external antenna of the
DTM. If you have any reason to suspect that
interference is taking place, switch off the
DTM immediately.
Hearing aids
The DTM radio signals may interfere with some
hearing aids. In such event move the antenna
as far away as practical or consult your hearing
aid supplier.
Other medical devices
Operation of any radio transmitting equipment,
including the DTM, may interfere with the
function of inadequately protected medical
devices. Consult a physician or the
manufacturer of the medical device to
determine if they are adequately shielded from
external RF energy or if you have any questions.
Switch off your DTM in health care facilities
when any regulations posted in these areas
instruct you to do so. Hospitals or health care
facilities may be using equipment that could be
sensitive to external RF energy.
Vehicles
RF signals may affect improperly installed or
inadequately shielded electronic systems in
motor vehicles (e.g. electronic fuel injection
systems, electronic anti-skid (anti-lock) braking
systems, electronic speed control systems, air
bag systems).
Check with the manufacturer or its
representative regarding your vehicle. You
should also consult the manufacturer of any
equipment that has been added to your vehicle.
Potentially explosive atmospheres
Do not install the DTM or site the antenna in
any area with a potentially explosive atmos-
phere and obey all signs and instructions.
Areas with a potentially explosive atmosphere
are often but not always clearly marked. They
include below deck on boats; chemical transfer
or storage facilities; vehicles using liquefied
petroleum gas (such as propane or butane);
areas where the air contains chemicals or
particles, such as grain, dust or metal powders.
Emergency calls
Important! The DTM, like any wireless phone,
operates using radio signals, wireless and
landline networks, as well as user-programmed
functions, which cannot guarantee connection
in all conditions. Therefore, you should never
rely solely upon any wireless phone for essential
communications (e.g. medical emergencies).
Remember, to make or receive any calls the
DTM must be switched on and in a service
area with adequate cellular signal strength.
Emergency calls may not be possible on all
wireless phone networks or when certain
network services and/or phone features are in
use. Check with local cellular service providers.
