Electrical Interference
SureFlap
®
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
®
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
®
.
5. Batteries
Now your flap is installed, insert the batteries to start operation. The unit requires 4x 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.

Based on normal usage. Note that heavy usage by many cats may reduce battery lifetime.
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 recommend the use of good quality, alkalinebatteries with SureFlap
®
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.
