TRANSMITTING MODES
OPERATION IN PTT MODE WITH STANDARD MICROPHONE (supplied)
Connect the 4-pin standard microphone to the microphone connector (12). Select the PTT operating mode by turning
the PTT/VOX GAIN control (5) fully counterclockwise until a click is heard (PTT mode position). Press and hold the PTT
button (16) to transmit and speak into microphone. Release the PTT button (16) to return to receive mode.
OPERATION IN PTT MODE WITH EXTERNAL MICROPHONE (supplied)
AND REMOTE PTT CONTROL (supplied)
The supplied external earset-microphone (ESM-555) and remote PTT control (RPT-1) allow operating the radio in total
comfort and safety, without using the standard microphone that may be disconnected from the radio and removed. The
external earset-microphone has two separate jacks, one jack is for the earset signal and the other jack is for the
microphone signal. Each jack can only be connected to its correct position. Connect the microphone jack into the left side
hole (1A). The external earset jack may be connected if you wish to listen through the earset or it may be not connected if
you wish to listen through the speaker. For operation with the earset, please refer to the section "RECEIVING MODE" at
page 9. Connect the remote PTT control jack (19) to the REMOTE PTT socket (8). Install the remote PTT control in a
convenient location, such as on the speed shift lever or on the steering wheel, using the velcro strap (20), for your most
comfortable operation during driving.
WARNING ! Pay the greatest attention to installation of the remote PTT control and its connecting cable, in order
for these not to interfere with your driving operation.
Set radio to PTT mode, by turning the PTT/VOX GAIN control (5) fully counterclockwise until a click is heard (PTT mode
position). Press and hold the PTT button (18) to transmit and speak into microphone with normal voice. Release the PTT
button (18) to return to receive mode.
OPERATION IN VOX MODE (HANDSFREE OPERATION) WITH EXTERNAL MICROPHONE (supplied)
VOX mode allows using the radio totally handsfree, by automatic switching between receive and transmit mode, for
great comfort and safety while driving. Radio is automatically switched to transmit mode when you speak into
microphone and is automatically switched back to receive mode when you are not speaking. Therefore in VOX mode
you do not need to operate any PTT (push-to-talk) switch. Then the standard 4-pin microphone and remote PTT
control can be disconnected from the radio and removed. To operate radio in VOX mode, you must connect the
external earset-microphone (ESM-555) supplied with the radio to the EXT MIC/EAR socket (1). The external earset-
microphone has two separate jacks, one jack is for the earset signal and the other jack is for the microphone signal.
Connect the microphone jack into the left side hole (1A). The external earset jack may be connected if you wish to listen
through the earset or it may be not connected if you wish to listen through the speaker. For operation with the earset,
please refer to the section "RECEIVING MODE" at page 9. However, in VOX mode it is recommended to use the
external earset, in order to prevent strong audio signals coming from the main speaker (or external speaker)
from triggering the VOX function into transmit mode. This may specially happen when the VOX gain control
(5) has been set to a high level. Set radio to VOX mode by turning the PTT/VOX GAIN knob (5) clockwise and the
VOX icon (L) will appear on the LCD. Adjust VOX gain (sensitivity) by turning the knob clockwise. To disable the VOX
function, just turn the PTT/VOX GAIN knob (5) fully counterclockwise, until a click is heard (PTT mode position).
Important !
1. VOX gain must be adjusted in accordance with the noise level in the background. A noisy background and an
excessively high VOX gain might cause VOX to be triggered into transmit mode when you do not want it.
Therefore Volume level and VOX gain level must be adjusted carefully for the best compromise and for your
comfortable operation of the radio.
2. In case of a noisy background and environment, all vehicle windows should be kept closed, to prevent external
noise from triggering VOX into transmit mode.

M. Icona LOW
L' icona LOW (M) è accesa quando il trasmettitore è in modalità Low Power (bassa potenza) del trasmettitore (1W).
7. Manopola CHANNEL (selettore dei canali)
Questa manopola permette la selezione dei canali a scatti di 1 canale per volta, in ordine crescente (manopola ruotata in
senso orario) o decrescente (manopola ruotata in senso antiorario).
8. Presa REMOTE PTT
Presa per il collegamento del comando PTT remoto (RPT-1) in dotazione.
Per il funzionamento fare riferimento al paragrafo "MODALITA' DI TRASMISSIONE" a pag. 21.
9. Manopola RF GAIN (guadagno del ricevitore)
Questo ricetrasmettitore utilizza un circuito ricevente con alta sensibilità e selettività. Il guadagno del ricevitore è
regolabile con la manopola RF GAIN (9). Ruotando la manopola in senso orario, il guadagno del ricevitore viene
incrementato. E' opportuno ridurre il guadagno del ricevitore in presenza di segnali molto forti e aumentarlo in caso di
segnali deboli o comunicazioni a lunga distanza.
10. Manopola AS/SQUELCH
COMANDO SQUELCH (regolazione manuale SQUELCH)
Il comando SQUELCH permette di silenziare il ricevitore, eliminando il rumore (fruscio) di fondo in assenza di segnali.
Ruotare la manopola in senso orario sino a quando scompare il rumore di fondo. Ruotare la manopola in senso
antiorario (apertura dello SQUELCH) per ascoltare i segnali più deboli.
COMANDO AS (regolazione fissa SQUELCH)
E' disponibile la funzione AS per silenziare il ricevitore in modo automatico, senza eseguire la regolazione manuale dello
SQUELCH. Una regolazione fissa dello SQUELCH è pre-impostata in origine. Per impostare la funzione AS, ruotare la
manopola completamente in senso antiorario fino a farla scattare in posizione AS.
11. Manopola OFF/VOL
Manopola di accensione e spegnimento della radio. Permette la regolazione del volume di ascolto. In assenza di segnali
sul canale in uso, si consiglia di aprire lo SQUELCH e quindi di regolare il volume al livello desiderato utilizzando come
riferimento il rumore (fruscio) di fondo.
12. Presa per microfono
Collegare il microfono tradizionale a 4-poli in dotazione a questa presa, bloccandolo tramite l’ apposita ghiera.
