b) PRECAUTIONS
Prevent Interference:
The EM Card reader is working at the frequency of 125Khz. Installation precautions are necessary.
• Make sure the location for installation has no strong low frequency electro-magnetic wave. Especially in the range
of 100-200Khz
• If there is more than one keypads with the same operation frequency installed closely in the location, make sure
that they are at least 60cm (2ft) apart from each other to prevention interference.
Prevent Accidental Short Circuit:
In the previous experience, most of the damages caused in the installation are accidental touching of the components
on circuit board with the wires carrying power. Please be patient to study the manual to become familiar with the
specications of the system before starting the installations.
• Do not apply power to the system while it is in installation.
• Check carefully all the wirings are correct before applying power to the system for testing.
