8.3 Time functions
8.3.1 Clock
The transmitter incorporates a real time clock to allow automatic switching
between night and day power and also to keep track of total days of operation.
The clock is backed up by a super capacitor that will keep time without mains
power for up to three weeks. Any longer without power will require the time and
date to be set when next powered up.
The clock does not automatically compensate for daylight saving.
8.3.2 Night-time power
If enabled, the transmitter can be programmed to automatically switch to a
different set power during the hours of darkness.
In this way it is possible to limit co-channel interference at night due to sky wave
propagation.
