Volume Control
Receiver volume control
The receiver volume control enables you to adjust the receiver volume on the handset. Press the BOOST button, the red LED will turn on, now
you can increase the receiver volume by rotating the 
knob (under the receiver) to the desired level ( level 1 to level 9).

Setting your earpiece volume too high can damage your hearing!!!

You can use the TONE slide switch to adjust high frequency sounds. Words are clearer and easier to understand. Note: The tone
adjustment function will not work if the receiver volume is set to the minimum level.
