Important Notice
TEST OPERATION WITH YOUR CAT BEFORE INSTALLATION
Please read all these instructions BEFORE fitting the SureFlap cat flap. Importantly, please check whether there is metal in the substrate the flap is to be fitted into. Please follow the metal mount instructions if this is the case.
Every effort has been made to ensure the SureFlap will operate with 9, 10 and 15-digit microchips that are commonly used for pet identification. However, there are a small number of circumstances relating to the position of your pet’s microchip and the signal strength of the individual chip, which may mean that the cat flap does not operate reliably.
We therefore strongly advise that the following checks are carried out before permanent changes are made to a door for mounting the cat flap:
1) Insert batteries and leave for 10s with nothing in the tunnel so the sensors can settle.
2) Press the ‘memory’ button and persuade your cat to put their head up to the door from the tunnel side. The flashing light will go out when their chip has been learnt.
3) Leave the flap until the lock closes again.
4) Finally, test the normal operation of the flap. Again persuade your cat to put their head up to the door from the tunnel side. Try to make sure this is similar to how they would use it in practice, as shown below. The catch should open.
5) Repeat
