24 Safety Instructions

• Keep the device and the external antenna at least eight (8) inches

from people.

• During a thunderstorm, disconnect the external power supply

and do not use the device.

• Some electronic devices are susceptible to electromagnetic

interference sent by devices that may not be adequately

shielded. For best performance, position the Wireless Home

Phone Base as far from these types of devices (TV sets, radios

and other automated ofﬁce equipment) as possible so as to

avoid possible electromagnetic interference.

• Do not use the device in hospitals.

• Do not use the device on board aircraft.

• Operating of the device may interfere with medical devices

like hearing aids and pacemakers. Consult a physician or the

manufacturer of the medical device before using.

• Be aware of usage limitations when using the device at places

such as oil warehouses or chemical factories, where there are

explosive gases or explosive products being processed. Even

if your terminal is in idle state, it still transmits radio frequency

(RF) energy.

• Do not touch the antenna while calling.

• Keep the antenna free from obstructions and position the

antenna straight up. This will ensure best call quality.

• Please put the device in a safe place. The device may cause injury

if used as a toy by children.

• Do not put other things on the terminal to avoid overheating.
