4. Electrical Specifications
4.1. Power Supply Specification
Modem power(V_BATT) should be provided DC3.8V ± 0.1V, 1.5A. Modem power is
provided according to inner function and per block using DC regulated circuit.
It is controlled with each power depending on the mechanism to reduce power
consumption to a minimum. PA is used directly V_BATT because of a lot of power input
power source. Thus, It can be resulted in breakage of PA in excess of the rated input
power.
In addition, surge and ESD should be designed to block the influx in order to prevent
damage to the modem.

11. RFx information
The RF field strength of the wireless module or modules that may be
embedded in your TCU is well all international RF exposure limits as known
at this time. Because the wireless modules(which may be embedded into
your TCU) emit less energy than is allowed in radio frequency safety
standards and recommendations, manufacturer believes these modules
are safe for use. Regardless of the power levels, care should be taken to
minimize human contact during normal operation.
This module should be used more than 20cm(8 inches) from the body
when wireless devices are on and transmitting.
This transmitter must not be collocated or operate in conjunction with
any other antenna or transmitter.
Operation is subject to the following two conditions: (1) this module may
not cause interference , (2) this module must accept any interference that
may cause undesired operation.
11.1 Information for integrator
The integrator has to be aware not to provide information to the end
user regarding how to install or remove this RF module in the user
manual of the end product.
The user manual which is provided by integrators for end users must
include the following information in a prominent location.
To comply with FCC RF exposure compliance requirements,
the antenna(W8E-MWC-20 Tri-band Dipole Antenna)
used for this transmitter must be installed to provide a separation
distance of at least 20cm from all persons and must not be co-
located or operating in conjunction with any other antenna or
transmitter.
Label for end product must include Contains FCC ID : YZP-D660V or
A RF transmitter inside, FCC ID : YZP-D660V
