The maximum output power will be 30 dBm.
The transmit cycle is a sequence of 57 data strings on 51 different
frequencies, each transmitted for 10 msec.
Every transmit cycle is 570 msec in duration (57 x 10ms).
The frequency hopping pattern is proprietary to Sapling and covers the range
from 914.688 to 927.488 MHz.
Connections:
The module should only be connected to and installed in other Sapling
products

Operation:
The module is controlled by the Master Clock and will not operate on its
own. When connected to a Master Clock as a main transmitter, it will
transmit the time for 570 ms, as specified, once a minute.
If used as a Repeater, it will receive time from a main transmitter or clock
and re-transmit the time thereby increasing the coverage area, thus keeping
all the slave clocks synchronized to the Master Clock.
FCC Statement:
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
