3.1.16 Tilt Switch
If selected, unit will respond to an interrogation with the normal respond ping, plus four additional pings
200 milliseconds apart, when the release is tilted more than 25 degrees from vertical.
3.1.17 Backup Timer
Note: As standard, this feature is NOT included in the release software. If requested, at
the time of order, the backup timer will be included, and operates as described in this
manual.
If enabled, the BACKUP timer will cause the 865 to automatically RELEASE a fixed number of hours
(up to 65,535 hours , > 7 years!) after the unit is turned on. This feature can be used in the very special
applications where a timed release function is desired. When this function is enabled, the unit will still
respond to an acoustically transmitted RELEASE command.
