REMOTE CONTROL FEATURES
The SENTRY CODE HOPPING products use an encryption technology
known as KEELOQ, which is a secure protocol that is exceptionally resistant
to grabbing and attempts at decryption. This protocol is also used by leading
automobile manufacturers for remote keyless entry.
These transmitters do not feature any user-settable dipswitches. The
transmitters are “learnt” into an available memory slot of a compatible
SENTRY receiver or SENTRY product equipped with a receiver. Due to the
encrypted nature of these transmitters, it is not possible to learn them into
receivers of other manufacturers, even though the same technology is used.
Each transmitter is also unique, and has a unique serial number which is not
duplicated. This also helps to simplify dealing with the issue of a stolen or lost
transmitter.

GENERAL LEARNING PROCEDURE
The procedure to learn a transmitter into a receiver follow the same general
principle. However there may be subtle differences on some products,
therefore it is always essential to refer to the user manual of the receiver
concerned.
Example: Learning a transmitter into the SENTRY DCC02 Roll Up GDO
Step 1: Press LRN on the wall console
Step 2: Press LRN again to increment to the desired memory slot
Step 3: Press the desired button on the transmitter
Step 4: The wall console beeps twice, indicating successful learning
Tips
- Always learn a transmitter at least 10cm away from any receiver. This
prevents overloading of the sensitive receiver which could lead to difficulty
in learning the remote into the receiver. When testing also observe this
distance to ensure reliable operation
- When a transmitter is lost or stolen, it is always good practice to erase it
from the receiver. Refer to the user manual of the specific product for
information on how to do this. This will prevent criminals who have gained
possession of the transmitter from using it to enter the property.
