13 Specify Start and End dates and times on the Program Times dialog.
14. Enable the selected Time ( Ö) so it will be used by the program.
15. Select and enable further start and end times, then click OK to confirm the selection.
16. To send the complete package of four programs to the Apex Pro, place the unit in range of the
infrared transducer, and click the Send to Pump button.
Please note: It is not possible to send an individual program to the pump.
The four current programs will be transferred to the pump, while a Pump Programming
Status dialog gives progress information.
The PC takes this opportunity to synchronise the clock in the Apex unit to the same time and date
as the PC.
17. Once the program has been sent to the Apex unit, the unit can be removed from the transceiver.
