ImmersionRC | EzOSD Manual

Alarms
The EzOSD is equipped with 4 settings which define alarms. When an alarm triggers, the relevant on-
screen readout will flash, to draw the pilot’s attention.
Figure 4: Alarms
The 4 alarms supported by the EzOSD are:
1. Low Battery
Defaults to ‘Auto’ mode, which assumes a LiPo flight pack. In this mode the number of cells is
automatically detected.
The alarm will sound when the battery voltage drops down below 3.2v/cell.
2. Pack Capacity
While flying, the number of mAh (milliamp-hours) consumed from the battery is recorded. Once it
reaches the trigger point set in the Pack Capacity alarm, the readout will flash, and it’s a good time to
head home.
3. Max Altitude
While flying FPV it is easy to exceed local regulations regarding maximum permitted altitude for model
flight. Set the Max. Altitude value to reflect these local regulations, and the altitude readout will flash
when this altitude is exceeded.
Remember: Altitude is always measured relative to the launch point in the EzOSD (AGL, vs. ASL).
4. Max. Distance
Set this alarm to warn when the plane is more than a pre-set distance from you.
Several of the worldwide modeling federations are starting to define rules for FPV flight on club fields.
These generally include the mention of a requirement to fly within visual range, or at least the visual
range of the spotter pilot which should be monitoring your flight.
Set the Max. Distance alarm to warn you before your spotter starts panicing.
Also useful to warn before your R/C uplink looses control!
