6615-2203

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.

RF energy

The GDW-11 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.
