For radio control operation the remote control system is complemented with a radio
transmitter, a battery pack, battery charger and radio receiver box.
( See also sections "Battery pack", "Battery charger" and " Control unit for battery operation" ).
11. RADIO TRANSMITTER.
The radio transmitter card ( which is encapsulated and has a well proven built-in antenna ) is
mounted onto the control unit electronics card ( HTX 402 ). The radio transmitter is connected
via a pin strip, to the electronics card and is screwed down using four fixing spacers. When
the radio transmitter is connected to the electronics card ( HTX 402 ), a unique identity code is
added automatically to the digitally coded control information. The radio transmitter is
approved in accordance with European radio standards I-ETS 300 220 and I-ETS 300 683.
The driver can make an immediate radio channel change by using control unit push button
"ON/SIGNAL/FREQ.SHIFT". The radio channel change can be made at any time during
operation. The radio transmitter operates in the 405 - 490 Mhz band.
For the mobile market 12 ( twelve ) radio channels in the I.S.M band ( 433.100-434.700 á 25kHz )
are available for use. ( United Kingdom : 458.500-458.950 MHz a ´ 25kHz ).
No special licence is required by the user for the frequencies for which the radio transmitter is
approved.
Changing the radio channel : A double press of the (FREQ. SHIFT) push button will make the system
execute an immediate radio channel change. Press the button twice quickly and the red LED should blink and the
control unit should beep once to confirm that a radio channel change has been made. A radio channel change can
be made at any time during operation. The system has twelve (12) radio channels as standard .
