diameter or larger. Drill to a depth 25mm less than the wall thickness. The
mid-size screw is now suitable for mounting the main assembly from the
outside. Alternatively the main assembly may be glued to the inside wall of the
house.
Electrical Interference:
SureFlap
TM
contains a sensitive radio receiver to pick up the signal from your
cat’s microchip. Excessive levels of electrical interference can cause the
range of the system to degrade. Avoid the following situations:
1. SureFlap
TM
should not be used in the vicinity of other microchip
readers or similar low frequency devices. These are particularly
detrimental to performance and may prevent normal operation.
2. Avoid obvious sources of electrical noise such as faulty, flickering
lights.
3. Avoid trailing mains cables and dc mains adaptors very close to
SureFlap
TM
.

Now your flap is installed, insert the batteries to start operation. The unit
requires 4 x AA 1.5V batteries. With normal usage, one set of batteries will
typically last for at least 6 months

. A low battery indicator tells you when the
batteries have run out and is described in section 8.
After inserting the batteries, leave the unit for about 10 seconds before
allowing a cat into the tunnel - this allows the electronic sensors to settle
properly.
We rec ommend the use of good quality non-rechargeable batteries with
SureFlap
TM
in order to give the longest lifetime. Rechargeable batteries may
also be used, however they generally produce a lower voltage and will not last
as long. You may need to recharge such batteries every few months.

Based on normal usage. Note that heavy usage by many cats may reduce battery lifetime.
