Handset range
Your eco50 handset has a range of up to 300 metres outdoors and up to 50 metres indoors, in ideal conditions.
If you carry the handset too far away from the base, you may go out of communication range and the antenna icon will flash on the display.
If you are already on a call and move out of range, the call quality will degrade as the range limit is reached and the call may be disconnected. You will need to move closer to the base to be able to continue the call and make any further calls.
Checking the signal strength
The signal icon 
displays the link status between your handset and the base unit. A steady icon means your handset and the base unit are linked. A flashing icon means your handset and the base unit are not linked.
If you move too far away from the base unit while you are on the phone, you will hear warning tones notifying you that your handset is almost out of range – lost link. Take your handset closer to the base unit or your call may be cut off shortly after the warning
Note:
If your handset has lost the link with the base, you will not be able to make or receive calls. You will also not be able to carry out many of the phone functions and features.
Important NOTE:
Emergency Call. This telephone is not designed for making emergency telephone calls when the power fails. Alternative arrangements should be made for access to emergency services.
