• The capsule transmits 406 MHz test signal. This signal does not initiate search and
rescue operations because the satellites recognize it as a test signal. However, do
not do the self test more than necessary.
• The capsule transmits 121.5 MHz homing signal in the self test. Aircrafts receive
this homing signal. Do the self test five minutes every hour on the hour because the
homing signal is recognized as a test signal during this time period.
• For VR-7024F, the capsule transmits the AIS messages in the self test. Normally,
the AIS message transmitted in the self test are not displayed on the AIS receiver.
• You can maintain the Float-free DRU and do the self test with the VDR powered.
However, the capsule should be returned to the bracket within 10 minutes after its
release. The data buffer of the VDR can retain the data of the latest 10 minutes. If
more than 10 minutes passes after releasing the capsule, the data of 10 minutes
before the capsule is returned to the bracket is lost. At this time, the communication
error with the Float-free DRU appears on the remote alarm panel. Finish any main-
tenance and diagnosis as quickly as possible to be prepared in case of an unex-
pected emergency and prevent loss of data.
• Apply the appropriate silicone grease between the docking module and storage
module before reattaching the capsule, to prevent water and foreign materials from
entering into the gap between the docking module and storage module. If foreign
material contacts the modules, electrostatic capacity may change, preventing re-
cording of data.
Note: Silicone grease is stored around the DCU after installing the Float-free DRU.
Use the tube labeled "Silicone Grease for Tron 40VDR". Use only the specified sil-
icone grease (type: 100946, code no.: 001-365-040). If the silicone grease is empty
or lost, contact your dealer.
