The radio's ability to declare an emergency, clear an emergency, remain locked on an emergency and 
group, and the emergency audio and display freeze can each be enabled or disabled through 
programming. When an emergency is declared scanning will stop and will restart only after the 
emergency has been cleared. 

When receiving an emergency call from the selected group and system, an alert beep is heard and the 
BSY indicator lights. The message *RXEMER* flashes in the display on line 2 until the emergency 
condition is cleared. Follow standard emergency procedures. 

To send an emergency call to the selected system and group (or on an optionally pre-programmed 
emergency group), proceed as follows: 

1.  Press and hold the red emergency button for approximately one second. (This time is programmable 

and therefore could be longer or shorter. Check with the system administrator.) The radio will 
transmit an emergency call request with the radio ID until an emergency channel assignment is 
received. 

2.  When the working channel assignment is received, the radio sounds a single beep (Autokey alert 

tone) indicating it is ready for voice transmission. *TXEMER* flashes on line 2 in the display until 
the emergency is cleared. 

3.  Press PTT and speak into the microphone in a normal voice. 

4.  Release PTT when the transmission is complete and listen for a reply. 

5.  The emergency can be cleared by pressing and holding the CLR button followed by pressing the red 

emergency button then releasing both buttons. 

The radio can be programmed with the following System Scan features. These features are automatically 
enabled upon radio power up. A key or menu option is also defined to allow the System Scan features to 
be toggled during radio operation. This is covered in the Menu Selection and Pre-Programmed Keypad 
Key sections. The System Scan state will be maintained through system changes but will default to ON at 
power up. 

The M7200 Series mobile radio can be programmed for wide area system scan operation for multi-site 
applications. Upon the loss of the currently selected system's control channel, radios can be programmed 
to automatically scan the control channels of other systems. If a new control channel is found, the radio 
will switch to the new system and sound an alert tone. 

The radio can be programmed for ProScan™ system scan operation for multi-site applications depending 
on the version of radio flash code. ProScan provides the radio with the ability to select a new system for 
the radio to communicate on, when the selected system drops below a predefined level. This is
