About the Operating Range

The Business Cordless 905 telephone handset and base can communicate over 
a distance of approximately 50 to 150 feet, depending upon the locations of the 
base and the handset, the weather, and the construction of your home or office.

The following descriptions identify some out-of-range situations that may occur. 

• If you hear two short beeps in the handset when you make a call, this 

indicates that you are out of range and the base and handset cannot 
communicate. The message CAN’T FIND BASE appears on the 
handset LCD display. If this happens, move closer to the base to restore 
normal operation.

• If you receive a call while you are out of range, the handset may not 

ring, or if it does ring, the call may not connect when you press PHONE
Move closer to the base and then press PHONE to answer the call.

• If you move out of range during a telephone conversation, you will be 

interrupted by silence, noise, or other interference. The message 
SEARCHING... will appear on the handset LCD display. The call will 
remain connected. To improve reception, move closer to the base.

• If you move out of range and lose communication with the base, the call 

will be put on HOLD. To retrieve the call, walk back into range, 
periodically pressing PHONE until you successfully communicate with 
the base (the CAN’T FIND BASE message will disappear from the 
handset display). Then press the line button to select the line that was 
put on HOLD.
