MOTOROLA MICRO T-A-C 550 Cellular Telephone 170-1996 Operation, Roaming & Sys. Faxback Doc. # 34069 There are generally two types of cellular systems servicing any metropolitan area. One of these will most likely e operated by the telephone company that provides telephone service to your community, generally referred to as a wireline carrier. The other Cellular Service Provider is a radio common carrier, referred to as a non-wireline carrier. Your Cellular Service Operator will provide information concerning specific features, procedures, and coverage in your particular area. Service Area The area within which the telephone operates is defined by your Cellular Service Provider. Since this is a radio system, no exact boundaries (as on a map) can be drawn. The red NoSvc (No Service) lights if you are beyond range of a service area. There may be locations within your area, such as tunnels and underground parking facilities where the unit may act as if it were beyond range. Weak Signal Alert If you are called while in a location the system determines is inadequate for high quality service, you may hear a series of beeps to inform you of the call attempt. The caller will receive the recorded "Not in Service" message, CALL appears in the display, and the green on indicator flashes quickly. If this occurs, you must press (CLR) before the unit will operate. Most systems do not impose air-time charges for such call attempts. This feature is usually turned off. NOTE: This indicator is controlled through the initial programming of your phone. Refer to the Programming Guide for more details. Roaming The term "Roaming" applies to the use of cellular telephones within systems other than those designated as their "Home" system. Roam lights whenever the unit comes within range of a visited system. As your phone begins to roam, it seeks service according to the conditions you have selected. Slow flashing of Roam signals that your phone unit is accessing a home type system, while rapid flashing indicates the unit is attempting connection through a non-home type system. Contact your system operator or that of the visited system, for information on dialing and billing procedures. To use alternate long distance services when roaming, be certain to dial the appropriate area code and local number to access the alternate carrier in the visited area. Then use the Tone Dialing sequence described on Faxback Doc. # 34066. If you selected Two-System Operation (see Faxback Doc. # 34065) enter (RCL), (#) to verify the currently active number. This is especially important if your two home systems have different area codes, or if Roam is flashing within home service area. Selectable System Registration To Review Current Setting: 1. Press (RCL), (*). The display will show the current active system choice. 2. Repeatedly press (*) to review the System Type modes. (Press (END) to exit without changing selections.) 3. Press (STO) to activate the displayed selection. System Type Selection Display C Scan CSCAn When programmed, this is the default setting. Standard Mode Your phone first seeks a home type system, then a non-home type. If home system is non-wireline (type A) StdAb If home system is wireline (type B) StdbA Invert Preference Mode Your phone first seeks a non-home type system, then home type. (Select this mode if in a fringe area of your home system or in certain roaming situations.) If home system is non-wireline (type A) SCAnbA Fast flashing Roam indicator = call on B system Slow flashing Roam indicator = call on home type system Slow flashing InUse indicator = call on home system If home system is wireline (type B) SCAnAb Flashing Roam indicator = call on A system Slow flashing Roam indicator = call on home type system Slow flashing InUse indicator = call on home system Home Only Mode HOME Phone will not operate outside its home system. Scan A Mode SCAn A Phone will operate only within non-wireline (A) systems. Scan B Mode SCAn b Phone will operate only within wireline (B) systems. Enter SID Mode (Available in some models only) PrEF'd SidS Unit will operate only within specifically identified systems. This choice requires entry of up to 15 System ID numbers for those systems over which you wish to operate. The SID digits are entered as obtained from your Cellular Service Operator. When Preferred SIDS is enabled, C Scan Mode is disabled. See below. Changing System Type The choice of System Type, as described on page 40, may be selected or canceled as follows: 1. Press (RCL), (*). The display shows the current active choice. Repeatedly press (*) until the desired System Type appears in the display. 2. If you chose Preferred SIDS, press (STO) and then enter the five-digit number at this time. Use (*) and (#) to move to the next SID location. 3. To activate the selection, press (STO). 4. To return to normal operation, press (END). NOTE: Constant flashing of the Roam indicator, or a steadily lit NoSvc indicator while within your home service area may indicate an unintentional choice has been made. If this occurs, re-enter System Type Selection to see if the unit is operating in Standard Mode, or if an alternate selection has been made. C Scan Your Motorola cellular telephone may be equipped with a special level of A/B System Selection called C Scan. Check with your service shop. This feature will limit the systems on which you can inadvertently operate and thus minimize billing problems. C Scan is a feature that must be activated or deactivated by a Motorola Authorized Service Center or dealer. When C Scan is activated Preferred SIDS will be deactivated. See above. If you review the Roam characteristics of your phone with the (RCL), (*) sequence, C Scan will be the first choice that appears in the display if you have at least one negative system ID entered. Repeatedly pressing (#) or (*) will scroll through the other five system selection choices as shown above. You may press (STO) to select an alternate choice when it appears in the display. Your choice will remain in effect until you turn off your telephone. On every power-up cycle, the telephone will automatically revert back to the C Scan mode of operation. When the NoSvc indicator blinks, you are either in an area that cannot give you service due to the C Scan mode, or when no cellular service is available. In either case, you may select another level of A/B system selection as described previously. If you have selected standard preference or invert preference and the NoSvc indicator is on, you are in a true "no service area" where cellular service is not available. (BR/EB 7/11/96)
