18.12 Auto-restart

This pump offers an auto-restart feature. If active on power loss, it restores the pump when power returns to the operating state it was in when power was lost. It does not operate when powering down in the middle of a dose: when the pump is restarted, it will await a press on the START key to begin the interrupted dose again. Auto-restart is retained while the pump is switched off. When the pump starts running, look for the ! symbol on the display. This ! symbol indicates that the pump is set for auto-restart.

￿The pump displays a screen allowing the user to activate auto-restart. Use the UP and DOWN keys to choose On or Off and press ENTER to confirm the decision.

￿If Off is chosen, the pump returns the user to the fourth screen of the Setup menu. The auto-restart facility will not operate.

￿If On is chosen, the pump returns the user to the fourth screen of the Setup menu, where an exclamation mark ( ! ) is now visible. This mark confirms that the auto-restart feature is in place and will operate the next time power is lost and restored.

Alternatively ...

￿Stop the pump. Turn off the mains power switch at the rear of the pump.

￿Hold down the START key and turn on the mains power switch. The ! symbol shows on the display.
