SkyView System Installation Guide - Revision K 15-7
Test Procedure
6. Set the SkyView display to full brightness (PFD > press SCREEN > press DIM > press FULL)
7. Fully charge the SV-BAT-320 Backup Battery. Reference the Battery Charging and
Battery Status Check sections for battery charging instructions.
8. Disconnect primary power from the SkyView display—ensure that the display is not
powered from another source
9. Clear the POWERING DOWN IN # SECONDS message (press STAY ON)
10. Allow the SkyView system to run off the backup battery
The system passes if, after 60 minutes, it has not turned off.
Repeat the test procedure for each backup battery in the system.
This test discharges the backup battery. Recharging the battery after the test is
recommended. Do this by applying primary power to the display. The backup
battery is fully charged when its voltage reaches 12.25 volts.
If a tested battery does not pass the annual backup battery test, please contact Dynon by
phone or the online store (store.dynonavionics.com) to obtain a replacement battery.
Please dispose of non‐functional SkyView backup batteries in a responsible
manner. SkyView backup batteries are lithium-ion and similar in construction to
cordless tool batteries. They can likely be recycled wherever cordless tool battery
recycling is available. For a list of recycling locations in your area (USA only), call 1-
800-8-BATTERY or see the Call 2 Recycle website at www.rbrc.org.

Network Configuration Does Not Work or SkyView Network Module Is Not Working
Properly
If you try and configure a SkyView network and it does not work, try the following:
Check network wiring and try again. There may be a short or an open somewhere.
Unplug network modules one by one and try again. It is possible that one of the
modules could cause the network to stop functioning.
Try again.
For modules such as the SV-ADAHRS-20X, the SV-EMS-220, and SV-ARINC-429, observe
the red LED light near the SkyView Network connector:
