6.15Custom Alarms
The custom alarm messages can be selected from a list of standard alarm messages or the operator can write his/her own message. A MAXIMUM OF TWO (2) ALARM MESSAGES CAN BE CUSTOMIZED. The two custom alarm messages will initially display the previously programmed message but can be changed.
The text for custom alarms can be changed at any time by selecting Custom Alarm. To change the text for a custom alarm, select the alarm you would like to change, 1 or 2. Using the Up and Down arrows, step through the list of five standard alarm messages (listed below) and two custom alarms. Select the alarm message desired and store it by pressing Enter.
