RA - 7203 Menus, 1 of 16 FbA FbC RS NOTE! RS can be pressed and turned. FbB The radio is controlled through an advanced menu system. The access for each menu is restricted by a user parameter. The System Operator can change all user parameters from SNMP, or from the menu using a hardware key.
RA - 7203 Menus, 2 of 16 There are four access user levels: User Name of menu: parameter: Access and restrictions: 1 System operator Full access to all parameters (R/W by System Operator) 2 Technician Access to some settings in RX menu system + bite (R/O) 3 Operators Access only to Volume, Frequency and memory store and recall 4 Restricted Restricted to Volume, Squelch and memory recall
RA - 7203 Menus, 3 of 16 When operated locally, the operator has full access to all facilities using the various controls at the front panel.
