8 CONTROLS
This section describes the buttons, keys and rotary knobs used to control the M7100IP Series Mobile Scan
and System Model radios. All functions and controls of the Scan radio operate the same as the
corresponding functions and controls on the System radio. The Scan radio is equipped with a 4-button
keypad and the System radio is equipped with a 16-button keypad.
Many of the control buttons and keys have been or can be programmed to have a primary function and a
secondary function. The SCAN button can be programmed (as a secondary function) to toggle the keypad
keys between their primary function and their secondary function.

into the radio to prevent missed calls due to a low volume setting. While adjusting the volume, the display
