HandyTechElektronikGmbHBraille WaveOperation of the Braille SystemPage 34The Delete function is the only function that applies to marked appointments. The otherfunctions in this submenu apply only to the currently selected appointment.Key assignments in the appointment editing menu: [ESC]: Return to the appointment schedule. [Enter]: Activate the selected menu item. All commands that can be used within the menu system are also valid.5.1.3.8 Information Regarding Past AppointmentsWhenever the Braille System is powered up and on an ongoing basis during the operationof the system, it monitors the appointment schedule to determine whether an appointmentis due or has passed while the Braille System was switched off. In either case, a repeatingwarning signal is emitted to indicate the appointment, and the description of theappointment is displayed blinking. The alarm signal can be turned off by entering [SPC+78], but the appointment must still be confirmed by pressing [ESC]. The Braille System thenreturns to whichever function was active before the appointment information wasdisplayed. If the appointment you just confirmed was a variable appointment, its nextoccurrence is automatically calculated based on the current date and time, and enteredinto the appointment schedule. The next occurrence of this appointment is also displayedon the Braille System and needs to be confirmed by pressing the [ESC] key. The text forthe appointment may stay till your next operation. If you want to skip the checking forappointments when switching on the device, you have to hold down [6] for some time whileswitching on. An additional high signal tone before the low signal tone will confirm this.5.1.3.9 Resources ManagementDepending on how you use the Scheduler, it may reduce the available memory on yourBraille System. You can prevent this from becoming excessive by deleting appointmentsthat have passed as soon as possible. The Scheduler will then utilize the freed-up memoryspace to store new appointments. The marking function (the [SPC] key within theappointment schedule) can be used to efficiently delete several appointmentssimultaneously. Up to 20 entries together can be deleted with one command with thisfunction. Since recurring appointments can result in the accumulation of a lot of data, theScheduler automatically deletes these while updating the variable values. This means thatan appointment containing variables is saved only once on the Braille System, under thenext due date.5.1.3.10 Backing up the scheduler dataIf you use the scheduler intensively, we recommend that you back up the related dataregularly. The scheduler data are kept in the file "PLANER.HSF". This is a system file(HSF = Handy Tech System file) and is therefore not normally shown in the file list.Just like any other file, the scheduler data can be transferred to a PC with the programHTCom. Further details of this can be found in the operating instructions "Transferring databetween the Braille System and a PC". In the file selection dialog of HTCom, there is acheckbox for displaying the system files. After activating this checkbox, you can select thefile "PLANER.HSF" and transfer it to your PC. We recommend that you deactivate thecheckbox again after transferring the file.Please note that you can only back up the file "PLANER.HSF" on your PC; you cannot editit there.
