If you press the enter key ( 8 ), the unit switches immediately back to the basic mode with
the new setting. You can also wait for 6 s, until the unit jumps into the basic mode by itself with
the new setting and a ringing signal tone.
In basic mode you can see in addition the writing Baby and the key lock symbol , which
indicate that the monitoring function for the monitored location is active now. In this state the
only possible operation is to activate the transmitter by the surrounding sound ( baby cries ),
which is also broadcasted with the actual CTCSS and scrambler settings to the unit of the
supervising person. All key entries except the enter key 8 ( 8 ) are rejected with a flashing of the
key symbol . There are no confirmation tone when you press a key. The loudspeaker is
always silent, even with a radio signal on the actual channel. See also the chapter “VOX func-
tion” for more information.
To deactivate the monitoring function for the monitored location depress the enter key ( 8 )
for 2 seconds, until the key lock symbol and the writing Baby disappear with a confirma-
tion tone.
The following instructions show how to activate and operate the monitoring function for the loca-
tion of the supervising person ( parents unit ):
Depress the menu key
&
( 5 ) six times. The display will build up the flashing writing OF out of
the numerical digits 88 in the lower right corner of the LCD window. Besides the flashing writ-
ing OF you can see only the writing Monitor, the actual channel number with its CTCSS code
number and the battery symbol. The next entry can only be made as long as the writing OF is
still flashing. With the help of the up/down keys
▲
( 7 ) and
▼
( 6 ) you can change the writing
OF into the writing ON and vice versa. To activate the monitoring function for the location of the
supervising person select ON.
If you press the enter key
( 8 ), the unit switches immediately back to the basic mode with
the new setting. You can also wait for 6 s, until the unit jumps into the basic mode by itself with
the new setting and a ringing signal tone.
In basic mode you can see in addition the writing Monitor, which indicates that the monitoring
function for the location of the supervising person is active now. In this state you can use near-
ly all functions of the unit, except transmission. The TX function can neither be activated by the
VOX function, nor with the PTT key ( 4 ) and nor with the call melody key C ( 9 ). Both keys are
rejected with a ringing signal tone. The monitoring function for the monitored location can also
not be activated. The writing remains always OF.
To switch off the monitoring function for the location of the supervising person depress the menu
key
&
( 5 ) again six times. The display will show again the writing Monitor, the actual chan-
nel number with its CTCSS code number and the battery symbol, together with the flashing writ-
ing ON. For a definitive deactivation of this function change with the help of the up/down keys
▲
( 7 ) and
▼
( 6 ) the writing ON into the writing OF.
If you press the enter key ( 8 ), the unit switches immediately back to the basic mode with
the new setting. You can also wait for 6 s, until the unit jumps into the basic mode by itself with
the new setting and a ringing signal tone.
Now the writing Monitor is no longer visible in the display.
6) Dual watch function
This function allows you to watch activity on two channels at a time, until it has found an occu-
pied one. In this case the squelch opens and the unit stops on that channel. The following
instructions show how to activate the dual watch function:
First select the first survey channel. Then select the dual watch function by pressing the menu
key
&
( 5 ) seven times. In the display appear flashing the number of the actual channel with
its CTCSS code number. Besides the flashing channel number and CTCSS code number you
can see constantly also the dual watch symbol DW and the battery symbol. Select now the
second survey channel with the help of the keys
▲
( 7 ) and
▼
( 6 ). The entry can only be made
as long as the channel number and the CTCSS code number are still flashing. Now the chan-
nel number and CTCSS code number appear also constantly. If on none of both survey chan-
nels is received a signal, the unit will step from one channel to the other two times every second.
Independent from the CTCSS setting of each channel, the CTCSS code number in the display
is always 00 during the surveying procedure. The dual channel survey stops on every occupied
channel and stays there, as long as the signal keeps the squelch open. In this period the dual
colour indicator LED ( 15 ) lights up green and the symbols RX and appear in the display.
In the case that the received signal carries also a CTCSS tone, the corresponding code num-
ber appears right beside the channel number. If the signal drops below the squelch threshold,
the channel number and the CTCSS code number begin to flash. If there is no signal for at least
4 seconds, the dual channel survey procedure continues searching.
You can select at every time another second survey channel with the help of the up/down keys
▲
( 7 ) and
▼
( 6 ).
To stop the dual watch function depress briefly the enter key ( 8 ).
If the dual watch function is terminated in that moment during which the unit is staying on an
occupied channel, the unit will use this channel as actual channel. In addition it will take over
that CTCSS code for this channel, which the station on that channel has been used at the halt
of the dual watch function.
If the dual watch function is terminated in that moment during which the unit is stepping be-
tween both channels, the unit will jump back to that channel, which has been the actual one on
starting the dual watch function. In this case the previous CTCSS settings of all channels remain
unchanged.
7) VOX function
While the VOX function is active, the unit switches automatically to transmit mode when the
sound level at the built-in microphone mic ( 12 ) is above a certain threshold. That sound will
also be broadcasted with the actual CTCSS and scrambler settings. If the voice loudness at the
microphone remains below this threshold for a certain time, which is called the VOX delay time,
the radio switches back to receive mode. Thus you can communicate without having a hand at
the unit. If the squelch is open because of a received signal the VOX function is inhibited. The
following instructions show how to activate the VOX function and how to work with it:
Depress the menu key
&
( 5 ) eight times, so that a flashing numerical digit appears in the
lower right corner of the LCD window. The flashing digit indicates the currently adjusted VOX
sensitivity level. The higher the value of the number is, the higher is the VOX sensitivity. The
unit is ready for adjusting the VOX sensitivity now. Besides the flashing VOX sensitivity level
number you can see only the actual channel number, its CTCSS code number, the writing and
the battery symbol. The VOX adjustment is only possible as long as the digit flashes.
Press the up key
▲
( 7 ) to increase the VOX sensitivity level number for one step.
Press the down key
▼
( 6 ) to decrease the VOX sensitivity level number for one step.
Pressing the keys for one second will make the VOX sensitivity level numbers change quickly.
The VOX sensitivity level numbers step in a ring like system. That means you go from level
number 4 via code OF to code 1 and vice versa. If the selected code is, the VOX function is
switched off.
