Operation of the TEAM ScramTalk-808
I. Directly accessible functions
1) Switching the unit On/Off
Depress the On/Off key ( 3 ) for about 1 or 2 seconds to switch the transceiver on. You can
hear two short receipt tones from the loudspeaker ( 13 ). For the period of the tones the display
( 2 ) shows all symbols. Now the unit is in receive mode and basic mode. The display ( 2 ) shows
the channel number and its corresponding CTCSS code, as well as various symbols indicating
the state of certain functions.
To switch the unit off depress the On/Off key ( 3 ) again for about 1 or 2 seconds. The loud-
speaker gives a long high tone and all symbols disappear from the display. The last settings
remain memorized. The unit is off now.
2) Battery level indicator
The battery symbol on the lower left side in the display shows the battery level. As long as
all three bars are visible inside the symbol, the batteries are still strong enough. If the supply
voltage drops below 3.6 V, the left bar disappears. If the supply voltage drops below 3.5 V, the
middle bar disappears. If the supply voltage drops below 3.4 V, the last bar disappears also. If
the supply voltage drops below 3.3 V, you will hear in the loudspeaker ( 13 ) every 15 seconds
three warning tones. That means that you have to change or charge the batteries. At supply vol-
tages below 2.8 V the display will show for one second the writing ( =BA LO = battery low )
with a flashing empty battery symbol outline, and then the unit switches itself automatically off
immediately afterwards.
The current consumption in TX mode amounts to 250 mA. In RX stand-by mode without recep-
tion of a signal it is 40 mA. For this end the ScramTalk-808 is equipped with a battery save fun-
ction. This function starts to work under the following conditions:
a) The functions channel scan and dual watch must be out of order.
b) For at least 5 seconds no signal is allowed to reach the receiver on the actual channel, no
key is pressed and no transmission occurs.
While this function is active the unit checks the actual channel for incoming signals in regular
intervals. The average current consumption in the power down mode drops down to 10 mA. On
receiving of a signal or pressing any key the power save mode switches itself off again.
But if you don’t use the unit it is better to switch it off. Another possibility is the use of the auto-
matic-power-off-function ( APO function ) which generates a total shut-off after a predefined
time. In switched-off mode the current consumption is reduced to 140 µA.
If you won’t use the unit for a extended period, we recommend to take the batteries or the accu-
mulator pack out of the battery compartment.
3) Volume level adjustment
To enter the volume adjustment mode from the basic mode you must press the up key
▲
( 7 )
or the down key
▼
( 6 ) first. The display will build up the writing ( = VOL ) out of the chan-
nel number display 218 and the CTCSS number display 88 for 0.5 seconds. Then the display
shows for 6 seconds only the channel number, the CTCSS code number, the battery symbol
and a flashing digit on the lower right side. During this time the unit is in volume level adjust-
ment mode. The flashing digit indicates the currently adjusted volume level. The higher the
value of the number is, the higher is the volume level. The amendment is only possible as long
as the digit flashes.

Press the up key
▲
( 7 ) to increase the volume level adjustment for one step.
Press the down key
▼
( 6 ) to decrease the volume level adjustment for one step.
Pressing the keys for one second will make the volume level adjustment change quickly.
The volume level of the confirmation tones depends from the currently adjusted volume level.
At the end of the adjustment range you will hear a ringing signal tone.
If you don’t press any of the up/down keys ( 7 ) and ( 6 ) for at least 6 s, the unit returns auto-
matically to the basic mode with the new setting and a ringing signal tone.
If you press the enter key ( 8 ), the unit switches immediately back to the basic mode with
the new setting and a signal tone.
The up/down keys ( 7 ) and ( 6 ) are without effect if the key lock function is active.
4) Disabling the noise suppression
The unit is always in receive mode as long as it is not in transmit mode. If there is no signal on
the actual channel, the receiver would produce much noise in the loudspeaker ( 13 ). Therefore
the unit is equipped with a circuit ( squelch ) that mutes the receiver if there is no station on the
actual channel. Any incoming signal will open the squelch at once while the busy symbol
appears in the display. Normally you can hear the station in the loudspeaker now. In addi-
tion there is another type of squelch which opens only when the counter station adds to its sig-
nal a correct CTCSS tone. But this CTCSS squelch is only working, if the CTCSS function is
active. In the case where the squelch lets signals pass, the symbol RX appears also in the dis-
play and the dual colour indicator LED ( 15 ) lights up green. The squelch function can be dis-
abled to hear also those stations which are too weak to make the squelch open by themselves
or other stations with a wrong CTCSS tone ( monitor function ). See also the chapter “CTCSS
function” for more information.
Depress shortly the monitor key M ( 10 ). Now the noise suppression is shut off. In the display
appears the symbol RX. If there is no station on the actual channel you hear a noise in the spea-
ker or the message if the channel is occupied. 15 s later the squelch function switches itself
automatically on again. To reactivate the squelch function at once depress the monitor key M
( 10 ) again.
5) Voice transmission
Before transmitting you have to hear whether the actual channel is free. Use also the monitor
key M ( 10 ). Don’t send on occupied channels. To transmit depress and hold the PTT key ( 4 ).
During transmission the dual colour indicator TX ( 15 ) lights up red and the symbol TX appears
in the display. No key entry is possible. Hold the unit upright. The sensitivity of the built-in micro-
phone mic ( 12 ) has been set to give good results speaking normally at a distance of 2 - 3
inches. Speaking too loudly will cause distortions and make the signal difficult to understand.
Your message will be sent out with the actual CTCSS and scrambler settings. On completion of
the transmission release the PTT key ( 4 ) and the set will revert to receiving mode.
Note: Radio contact is only possible with stations which work on the actual channel. In case of
CTCSS operation the CTCSS code number must match also. See also the chapters “Channel
selection” and “CTCSS function” for more information.
6) Call melody transmission
By pressing the call melody key C ( 9 ) you can transmit the actual call melody with the actual
CTCSS and scrambler settings one time. It is also audible in the internal loudspeaker ( 13 ). All
stations in the neighbourhood which are on the same channel will hear it. During transmission
the dual colour indicator TX ( 15 ) lights up red and the symbols TX and appear in the dis-
play. No voice transmission is possible while the call melody is sent out.
Afterwards the unit switches back to receive mode.
