2.3 Typical application
2.3.1 For base：
The cordless base using the MD-1562 contains a base band section & a RF section. The
antenna(s) will be located outside the module PCB area. To compose a base, the module will
need the additionally hardware interface to support line interface、power supply、handset
charger interface...
Page: 6 of 19
2.3.2 For data application：
The MD-1562 for data application can be executed as a MD-1562 base, combined with
one co-processor, which then by the control of the module able to send data back and forth
using the up to 32 Kbits/s air interface.
It is possible to establish a data link from up to five handsets to one base and routing the
data via the UART interface. However, the UART interface has a limited transmission speed up
to 115.2Kb/s baud rate. If more data connections are active at the same time and exceeding the
capacity of the serial bus, the bandwidth of the bus is shared equally between the data
connections.
For the base with MD-1562, it is possible to send data from one handset to another. It is
possible to send Low Speed (6.4Kbits/s) data between two handsets in an intercom through the
base unit.

7. Safety information
The equipment has been tested and found to comply with the limits for a Class B Digital Device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generate, uses and can radiate
radio frequency energy and, if not installed and used in accordance with the instruction, may cause
harmful interference to radio communication. However, there is no grantee that interference will not
occur in a particular installation. If this equipment dose causes harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
The changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
To comply with the FCC RF exposure compliance requirements, this device and its antenna must not
be co-located or operating to conjunction with any other antenna or transmitter.

To OEM installer:
1. FCC ID label on the final system must be labeled with "Contains FCC ID: XFT-TELOMD15" or
"Contains transmitter module FCC ID: XFT-TELOMD15 ".
2. In the user manual, final system integrator must be ensured that there is no instruction provided in
the user manual to install or remove the transmitter module.
3. Transmitter module must be installed and used in strict accordance with the manufacturer is
instructions as described in the user documentation that comes with the product. This device complies
with the following radio frequency and safety standards.
The user manual of the final host system must contain the following statements:
