How and When the Sleep code is sent:
The Sleep Code Data Packet will be sent:

After depressed key, <K1> say, is released and two Data-Packets of K1 Break Code sent, the RF Transmitter will be turned OFF. If no other key press activities are
detected after 5 seconds, the RF Transmitter will then be turned ON to send two data packets of Sleep code , the RF Transmitter will again be turned OFF and the
remote software goes into its actual Sleep mode.

How and When the repeated Make Code is sent:
The repeated Make Code Data Packet will be sent:
 After a depressed key, <K1> say, is detected, two data packets of its Make code will be sent with 10 ms delay between data packets. The
Make code packet of the same key will be sent out for every 70 ms time interval as long as this <K1> is still being held down and the overall
time since its first key press detection does not exceed 60 seconds.
