User's Manual

The way an alarm is processed in an LRMS (E2) DECT Handset depends on the Acknowledge/
Negative Acknowledge (ACK/NAK) structure, as shown in Figure 32: Alarm processing on
page 104.
• ACK/NAK
A message can be sent to an LRMS (E2) DECT handset as a Normal message, or as an
Urgent message. After a message is sent as a Normal message, the DMC sends an
Acknowledge at the moment that the message arrives at the handset. No manual
confirmation is required. If the message was sent as a sent message (reset after sent) the
alarm call is cleared on this Acknowledge. If a message is sent as an Urgent message, the
alarm call is cleared after the second Acknowledge arrives. After the user presses the Delete
or OK key on the handset, the message call is acknowledged.

For alarm handling, bear in mind the following when setting up the system:
• An alarm is set in a data table in the eKERNEL.
• Although the alarm is set in a table in the eKERNEL, the alarm is always set on a
Device.
• Because an alarm is set on a device, the alarm can only be reset on a device.
