If at any time an additional alarm occurs which is of higher priority on the task list than the alarm being
announced (i.e., #8 RPM is being announced and #4 Oil Pressure is activated), the AV-17 will announce the
higher priority alarm next, and then announce the remaining alarms on the task list.
B. Power-up Announcement:
When power is applied to the AV-17 and the Control Panel Switch is placed in the ON position, the unit
will announce Voice Annunciator enabled. Have a nice flight. This announcement will be made only once, at
the beginning of each flight.
C. Acknowledging and Silencing an Alarm:
There are two ways to silence an AV-17 alarm. One way is to acknowledge the alarm on the faceplate of the
instrument which generated the alarm (see the appropriate instrument manual). Alarms such as Altitude, Timer,
Low Fuel, etc. can be acknowledged and silenced in this manner.
Other alarms such as Oil Pressure, Oil Temperature, RPM, etc., cannot be silenced at the instrument generat-
ing the alarm. To acknowledge and silence these alarms, as well as any
active alarm,
push the Switch on the AV-
17 Control Panel momentarily to the ACK position. A high tone beep will be heard in the headset and all
active
alarms
will be silenced for one minute. This is handy if you do not want to permanently shut off any alarms but
you need silence for a minute to deal with other pressing matters. After one minute the silenced alarms will once
again be announced in the headset.
Note:
During the time one or more alarms are silenced, any newly activated alarm will be announced immediately
in spite of the minute of silence. To silence this new alarm, once again push the Control Panel Switch one time
momentarily to the ACK position.
D. Acknowledging and Silencing an Alarm for 10 Minutes:
To acknowledge and silence any
active alarm
for 10 minutes, within three seconds or less push the AV-17
Control Panel Switch to the ACK position three times. On the third push, a low tone beep will be heard in the
headset, indicating that all
active alarms
will then be silenced for 10 minutes.
