Status of the
receiving unit
URX-2
The receiving unit URX-2 has three working modes:
- free: it can be used by the transmitting unit that first requests its control. The receiving unit
has this status when the lamps or horns (if present) are not switched on
- engaged: it is reserved but not used by one of the transmitting units, which is off. It cannot
be used by the other transmitting unit until it is released and therefore set to the free status
by the transmitting unit that is controlling it. The receiving unit has this status when one of
the two lamps (or horns) ENA-M or ENA-S is ON blinking slowly
- engaged and used: it is reserved and used by one of the two transmitting units and cannot
be used by the other until it is released and therefore set to the free status by the transmitting
unit that is controlling it. The receiving unit has this status when one of the lamps or horns (if
present) is not switched on.
A transmitting unit that has engaged the receiving unit URX-2 keeps control on it even
after the STOP pushbutton has been activated or after the transmitting unit has been
switched off.
The receiving unit URX-2 gets back to its free status:
- if it is disconnected from its power source
- if it is released by the transmitting unit that had engaged it; release takes place
when the “Take/Release 2” or “Release 2” command is activated.
4.2 Power on and start up
Transmitting
unit UTX-M
The following procedure allows the transmitting unit UTX-M to work with the receiving unit URX-
1 only (single mode):
1.To switch on the transmitting unit UTX-M, insert the starting keyswitch and turn it to “I” po-
sition.
2.To start the radio remote control functions, press the START pushbutton for 3-4 seconds. After

In order to engage the receiving unit URX-2 (single or tandem mode), follow the procedure in
paragraph 4.1.
In order to activate commands, follow instructions given in paragraph 6.1.
Transmitting
unit UTX-S
The following procedure allows the transmitting unit UTX-S to engage the receiving unit URX-2
when it is free (single mode):
1.To switch on the transmitting unit UTX-S, insert the starting keyswitch and turn it to “I” po-
sition.
2.In order to start the functions of the radio remote control, keep the START pushbutton pressed
until the lamp (or horn) ENA-S switches ON steadily. After start up, the green signalling
LED in the transmitting unit always lights up.
