1 EPM-1000 User Manual
1.1 EPM-1000 usage
The EPM-1000 wireless push button is used to trigger the Text-To-Speech (TTS) in the dynamic
display IBD3750. IBD3750 is a 5-row LCD display for bus stops that shows bus departures and
passenger information.
1.2 EMP-1000 technical functionality
The EMP-1000 wireless push button contains an ISM UHF radio operating in the 915 MHz band. The
ISM UHF radio is powered by a Lithium Thionyl Chloride battery.
When the button in the EPM-1000 is pushed, the EPM-1000 will transmit a radio signal that is
detected by the display IBD3750. On receiving the radio signal from the EMP-1000, the display
IBD3750 will start the TTS functionality, and will make an audio presentation of the information
shown on the display rows.
2 FCC and IC statements

This device complies with FCC Rules Part 15 operation is subject to the following two conditions:
1. This device may not cause harmful interference.
Axentia Technologies 1-B iBus EPM-1000 wireless push button User Manual v2.0.docx
2. This device must accept any interference, including interference that may cause undesired operation
of the device.
Changes or modifications to this device, not expressly approved by Axentia Technologies AB could
void the user’s authority to operate the equipment.
FCC RF Exposure Requirements: This product complies with the FCC RF exposure limit set forth for
an uncontrolled environment and is safe for intended operation as described in this manual. This
device is only authorized for use in a mobile application, at least 20 cm of separation distance between
the radiating antenna and the user's body must be maintained at all times. Further RF exposure
reduction can be achieved if the product can be kept as far as possible from the user’s body or set the
device to a lower output power if such a function is available. Separate approval is required for all
other operating configurations, including portable configurations with respect to 47 CFR Part 2.1093
and different antenna configurations.
