Safety Notices
1) Please read all instructions before installing and powering the unit. You should keep
these instructions in a safe place for future reference.
2) The WR44 range is supplied with a 12VDC/1.5A power supply (mains adapter). If the
mains adapter shows signs of damage or malfunction, you should stop using it
immediately, turn off the power at the mains and disconnect it from the mains supply
before contacting your supplier for a repair or replacement.
3) Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment. Use only the
accessories, attachments, and power supplies provided by the manufacturer –
connecting non-approved antennas or power supplies may damage the unit, cause
interference or create an electric shock hazard, and will void your warranty.
4) Do not attempt to repair the product. The unit contains no electronic components that
can be serviced or replaced by the user. Any attempt to service or repair the unit by
the user will void the product warranty.
5) Products in the WR44 range are designed for indoor use only and should be used in
an environment that is suitable for computers and other electronic equipment.
6) Ports that are capable of connecting to other apparatus are defined as SELV ports.
To ensure conformity with IEC60950-1 ensure that these ports are only connected to
ports of the same type on other apparatus.

The wireless networks supported by the WR44 series routers fall into two categories:
• GSM networks (GPRS, EDGE)
• WCDMA networks (UMTS, HSDPA, HSUPA )
The type of network supported by each model is summarised in the table below:

Special notes on safety for wireless routers.
Digi International products are designed to the highest standards of safety and
international standards compliance for the markets in which they are sold. However, GSM
based products contain radio devices which require specific consideration. Please take
the time to read and understand the following guidance. Digi International assumes no
liability for an end user’s failure to comply with these precautions.
Wireless routers incorporate a wireless radio module. Users should
ensure that the antenna(s) is (are) positioned at least 1 metre away from
themselves and other persons in normal operation.
When in a hospital or other health care facility, observe the restrictions on
the use of mobile phones. Do not use the router in areas where
guidelines posted in sensitive areas instruct users to switch off mobile
phones. Medical equipment may be sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical
equipment and hearing aids can be affected by interference from cellular
terminals such as the wireless routers when placed close to the device. If
in doubt about potential danger, contact the physician or the
manufacturer of the device to verify that the equipment is properly
shielded. Pacemaker patients are advised to keep the wireless router
away from the pacemaker while it is on.
Wireless routers must NOT be operated on aircraft. The operation of
wireless appliances in an aircraft is forbidden to prevent interference with
communications systems. Failure to observe these instructions may lead
to the suspension or denial of cellular services to the offender, legal
action, or both.
As with any electrical equipment, you should not operate your wireless
router in the presence of flammable gases, fumes or potentially explosive
atmospheres. Radio devices should not be used anywhere that blasting
operations are taking place.
Wireless routers receive and transmit radio frequency energy while
switched on. Remember that interference can occur if it is used close to
TV sets, radios, computers or inadequately shielded equipment. Follow
any special regulations and always switch off your wireless router
wherever forbidden or when you suspect that it may cause interference
or danger.
SOS IMPORTANT! – Wireless routers operate using radio signals and
cellular networks cannot be guaranteed to connect in all possible
conditions. Therefore, you should never rely solely upon any wireless
device for life critical communications.
