For Vehicles equipped with an airbag
An air bag inflates with great force. DO NOT place objects, including either installed or
portable wireless equipment, in the area over the air bag or in the air bag deployment
area. If in-vehicle wireless equipment is improperly installed and the air bag inflates, seri-
ous injury could result.
Blasting areas
Do not use the unit where blasting is in progress or in “blasting areas”.
Observe restrictions and follow any regulation or rules.
Explosive atmospheres
Do not use the unit in any area with a potentially explosive atmosphere.
Potentially explosive areas are often, but not always, clearly marked.
They include fuelling areas such as petrol stations, below decks on boats, fuel or chemical
transfer or storage facilities, and areas where the air contains chemicals or particles, such
as grain, dust, or metal powder.
RF energy
The DR-260/3G is a low power radio transmitter and receiver. When it is ON, it receives
and also sends out radio frequency (RF) signals.
Most modern electronic equipment is shielded from RF signals. However, certain elec-
tronic equipment may not be shielded against the RF signals from the wireless unit. All
radio-transmitting devices send signals, which may cause interference in different elec-
tronic devices. To avoid interference, place the units antenna a sufficiently long distance
from other electronics.
Critical applications
Cellular units operate using radio signals and cellular networks cannot be guaranteed to
connect in all conditions. Therefore you should never rely solely on a wireless device for
essential communications, for example medical emergencies.
Backup copies
Remember to make backup copies of all important data, for example PIN/PUK codes,
contents of SIM card etc.
Antenna care
Use only the supplied or an approved replacement antenna. Unauthorized antennas,
modifications, or attachments could damage the unit and may violate current regulations.
Do not touch the antenna unnecessarily when the unit is in use. Contact with the anten-
na affects call quality and may cause the unit to operate at a higher power level than
otherwise needed.
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.
