1.3. Safety Precautions
Restrictions on the router use near other electronic devices:
Power off the modem in medical centres and keep it away from medical equipment (cardiac
pacemakers, hearing aids). Medical equipment may be susceptible to any form of radio interference. In
such areas the modem can transmit signals that could interfere with this equipment.
Power off the modem in an aircraft. Take measures against accidental activation.
Power off the modem near gas stations, enterprises of chemical industry, in areas where blasting
operations are in progress. The modem can interfere with operation of technical devices.
At close range the modem can interfere with television and radioreceiver operation.
To ensure safe operation, follow the recommendations:
Do not expose the modem to aggressive influences (high temperatures, corrosive chemicals, dust,
water, etc.).
Protect the modem from impacts, falls and excessive vibration.
Do not attempt to disassemble or modify the modem. Such actions will void the warranty.
Note: Use the device in compliance with the operating instructions. Damages caused by improper use and
storage of the device are not covered by the warranty.
