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: System operator Full access to all parameters (R/W by System Operator) Technician Access to some settings in RX menu system + bite (R/O) Operators Access only to Volume, Frequency and memory store and recall 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. Push RS to switch in the operator menu RA - 7203 Menus, 4 of 16 Push menu button to enter MAIN MENU RA - 7203 Menus, 5 of 16 RA - 7203 Menus, 6 of 16 RA - 7203 Menus, 7 of 16 RX config subtree menu, 1 of 2 RA - 7203 Menus, 8 of 16 RX config subtree menu, 2 of 2 RA - 7203 Menus, 9 of 16 Interface config subtree menu, 1 of 2 RA - 7203 Menus, 10 of 16 Interface config subtree menu, 2 of 2 RA - 7203 Menus, 11 of 16 Bite system subtree, 1 of 2 RA - 7203 Menus, 12 of 16 Bite system subtree, 2 of 2 RA - 7203 Menus, 13 of 16 To maneuver in the menu systems, use the up-button FbA, the down-button FbB or (preferably) turn the RS. The different submenus are selected by pressing the rotary switch and turning up/down until the desired menu is reached. (FbA, FbB and FbC may be used as well) To return to previous menu, press RS (or FbC) when “ ,,,” is selected in the present menu. The RA-7203 will enter the Operator menu when turned “ON”.
