The signal is received by the outside antenna from the cell tower, then amplified and 

transmitted to your phone through the inside antenna. When the phone transmits, the 

signal is received by the inside antenna, then amplified and transmitted to the cell tower 

through the outside antenna. 

Now you are ready to make and receive cell phone calls with powerful signal 

amplification!  Note that it is normal for the Amplifier’s case to be warm during 

operation. 

Press any cell phone key to refresh its communication with the base station. If your 

signal is weak, having this Amplifier installed and operating properly will give you a large 

increase in the signal strength and quality. The change in the signal strength can be 

seen on the visual display of your cell phone, and heard on your receiver or headset. To 

see the difference, try operating your phone in an area that is known to have weak cell 

phone signals. You will be amazed at the dramatic difference the PHONETONE Signal 

Amplifier provides! 

 

 

 

During using your Amplifier, if the Amplifier interferes with your radio or other electronic 

device, move the Amplifier further away from those devices, you might be able to solve it 

yourself.
