4 Module integration instructions
The VTAP50 OEM module has been designed to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may cause
undesired operation
These instructions must be followed to maintain the FCC approval for the VTAP50
OEM module, when it is integrated into a host system.
CAUTION:
Changes or modifications made to the VTAP50 OEM module, that have not been
expressly approved by Dot Origin Ltd could void the user's authority to operate the
equipment.
4.1 Applicable FCC rules
The VTAP50 OEM module operates at 13.56MHz and is therefore subject to FCC rules for
radio frequency devices. When a pass is presented to the reader, a person comes within
10mm of the device, so the rules relating to 'portable' transmitters apply.
4.2 Specific operational use conditions
The VTAP50 OEM module must be stored and operated under the following conditions:
l
Ambient temperature -25 to +70°C (-13 to 158°F)
l
Humidity 0 to 95% RH non-condensing
l
Pressure 86-106kPa
4.3 RF exposure considerations
This module complies with FCC RF radiation exposure limits set for an uncontrolled
environment. It is expected that VTAP50 OEM modules will be mounted in places that make it
possible for people to come within 10mm of the unit and it is therefore defined by the FCC as
a 'portable' device.
Screened cable should be used, wherever possible, to connect VTAP50 OEM modules to
other devices, to avoid interference from other equipment.
The end-user manual for the host equipment, that contains a VTAP50 OEM module, must
clearly indicate the operating conditions to be observed, so that the user remains in
compliance with current FCC RF exposure guidelines.
