Setup of TEAM McTalk 446
Removing and mounting of the belt clip ( 16 )
Removing: Turn the unit that way that the rear panel lies in front of
you. The latch of the belt clip is located near the headset sockets
SP./MIC/CHG ( 15 ). Pull the latch with the finger nail towards you
and hold it for a moment. Push the belt clip at the same time towards
the top of the antenna ( 1 ). Then you can take it off.
Mounting: Insert the belt clip from above into its
sliding bar on the rear panel of the unit. Then
push the clip towards the unit’s bottom side until
the belt clip latch clicks into place.
Inserting the batteries
Turn the unit that way that the rear panel lies in front of you. The
locking of the battery compartment lid ( 8 ) is located at the bottom
side of the unit. Push the locking aside and turn it down. Then, you
can take off the lid.
Now, insert 4 alkaline or rechargeable AAA ( = Micro ) cells into the
battery compartment according to the polarity signs inside. If you
use rechargeable cells we recommend the NiMH type.
To close the battery compartment ( 8 ) put the lid
onto the compartment in that way that the guide
bolt at the top of the lid grips into the guide hole
at the top of the battery compartment.
Finally secure the lid by pushing the locking on
it until it snaps in the battery compartment.
Operation of TEAM McTalk 446
1) Switching On/Off
Depress the On/Off key ( 13 ) for about 1 or 2 seconds to switch
the transceiver on. You can hear two short receipt tones from the
English
speaker ( 7 ). For the period of the tones the display ( 2 ) shows all
symbols. Now the unit is in receive mode. When the unit is
switched on, the first time after the batteries have been inserted,
the channel number will be channel 1 ( = 446,00625 MHz ). To
switch the unit off, depress the On/Off key ( 13 ) again for about
1 or 2 seconds. The speaker gives a long tone and all symbols dis-
appear from the display. The last settings remain memorised.
2) Battery level indicator
The battery symbol on the upper right side in the display shows the
battery level. As long as both bars are visible inside the symbol,
the batteries are still strong enough. If the supply voltage drops
below 4.4 V, the left bar disappears. If the supply voltage drops
below 4.1 V, the other bar disappears also. Now, the battery sym-
bol is blinking and in the loudspeaker you will hear every 5 sec-
onds a warning melody. That means that you have to change or
charge the batteries. The unit will automatically shut off if the sup-
ply voltage drops below 3.7 V. The McTalk 446 is equipped with a
battery save function. If there is no signal on the actual channel for
at least 6 seconds, and if no key is pressed during this period, the
battery save function starts to work. While this function is active
the unit checks the actual channel for incoming signals in regular
intervals. The current consumption in the power down mode drops
down to 13 mA. But if you don’t use the unit it is better to switch it
off. If you won’t use the unit for a longer period, we recommend to
take the batteries out of the battery compartment.
3) Volume level adjustment
The bars meter in the lower right side of the display shows the
currently adjusted volume level. Press the up key ▲ ( 3 ) to
increase the volume level adjustment for one step. Press the
down key ▼( 4 ) to decrease the volume level adjustment for one
step. Pressing the keys for one second will make the volume level
adjustment change quickly. The height of the confirmation tones
depends from the currently adjusted volume level. At the end of
English
16 17

the adjustment range two high signal tones are audible. The keys
( 3 ) and ( 4 ) are without effect if the key lock function is active.
4) Disabling the noise suppression
The receiver is equipped with a circuit ( squelch ) that mutes the
receiver if there is no station on the actual channel, because there
would be much noise in the loudspeaker ( 7 ). Any incoming sig-
nal will make the squelch switch on the loudspeaker at once. So
you can hear the station in the loudspeaker. In the case where the
squelch lets signals pass, the symbol ( = BUSY ) below the bat-
tery symbol appears and indicates that the channel is occupied.
The squelch function can be disabled to hear also weak stations
( monitor function ).
Depress shortly the Monitor key M ( 10 ). Now the noise suppres-
sion is shut off. In the display appears the symbol ( = BUSY ). If
there is no station on the actual channel you hear a noise in the
speaker.
To reactivate the squelch depress the Monitor key M ( 10 ) again.
Thus the squelch works again. If there is no station on the actual
channel, the symbol ( = BUSY ) disappears from the LCD window.
5) Voice transmission
Radio contact is only possible with stations which work on the
actual channel. Before transmitting you have to hear whether the
actual channel is free. Don’t send on occupied channels. To trans-
mit depress and hold the PTT key ( 12 ). During transmission the
red TX control lamp ( 14 ) lights up red and no key entry is possi-
ble. The sensitivity of the built-in microphone ( 9 ) 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 dif-
ficult to understand. On completion of the transmission release
the PTT key and the set will revert to receiving mode.
6) Call tone transmission
By pressing the call tone key C ( 5 ) you can transmit a call sig-
nal. The call signal will be transmitted for three seconds and is
English
also audible in the internal loudspeaker ( 7 ). All stations in the
neighbourhood which are on the same channel will hear it. Then
the unit will switch back to receive mode.
7) LCD window illumination
By pressing the enter key ( 6 ) the backlight of the LC display
lights up. The illumination will switch off automatically four seconds
later. The LCD backlight will also be switched on, if the menu key
( 11 ) is pressed to select an instruction and switched off if the
enter key ( 6 ) is pressed to confirm the selected instruction.
8) Key lock function
To prevent an unwanted activating of most keys, depress the
enter key ( 6 ) for 2 seconds until the key lock symbol ( key )
appears with a confirmation tone on the lower left side in the dis-
play. Now you can only send, deactivate the squelch and switch
the unit off and on. To deactivate the key lock depress the enter
key ( 6 ) again for 2 seconds, until the key lock symbol
( key ) disappears with another confirmation tone.
9) Channel selection
The McTalk 446 is equipped with 8 channels. The following
instructions show how to select a channel: Depress the menu key
( 11 ) one time, until the number of the actual channel flashes
in the LCD window. The channel selection must be done as long
as the channel number is still flashing, otherwise the unit returns
to the normal mode without changing the channel. Press the up
key ▲( 3 ) to increase the channel number for one channel. Press
the down key ▼( 4 ) to decrease the channel number for one
channel. Pressing the keys for one second will make the channel
number change quickly. The height of the confirmation tones
depends from the current channel number. The channels step in
a ring like system. Depress the enter key ( 6 ) to terminate the
channel selection and to return to the normal receiving mode.
No channel selection is possible in key lock mode.

10) Channel scan function
If the channel scan function is active, the unit runs through all
channels, until it has found an occupied one. In this case the
squelch opens and the unit stops on that channel. The following
instructions show how to activate the channel scan function:
Depress the menu key ( 11 ) two times, until the channel scan
symbol ( = SCAN ) flashes in the LCD window. Depress the keys
( 3 ) or ( 4 ) to start the channel scan into the desired direction.
According to the chosen direction the channel number increases
or decreases and the scan symbol ( = SCAN ) appears constant-
ly. The scanning stops on every occupied channel for 4 seconds
and then continues searching. To deactivate the scan function
and to stay on the actual channel, you have 4 options:
a) Depressing the enter key ( 6 ).
b) Depressing the PTT key ( 12 ).
The unit will transmit immediately.
c) Depressing the call tone key C ( 5 ).
The unit will transmit immediately the call tone.
d) Depressing the menu key ( 11 ) four times.
11) Dual watch function
This function allows you to watch activity on two channels at a
time. The following instructions show how to activate the dual
watch function: First select the first survey channel. Then depress
the menu key ( 11 ) three times, until the dual watch symbol
( = DW ) flashes in the LCD window. Depress the keys ( 3 ) or ( 4 )
to select the second survey channel. Now the dual watch symbol
( = DW ) appears constantly. If on none of both survey cannels is
received a signal, the unit will step from one channel to the other
two times every second. If on one of these channels is received a
signal, the unit will remain on it until the channel is free again. To
deactivate the dual watch function and to stay on the actual chan-
nel, you have 4 possibilities:
English
a) Depressing the enter key ( 6 ).
b) Depressing the PTT key ( 12 ). The unit will transmit immediately.
c) Depressing the call tone key C ( 5 ).
The unit will transmit immediately the call tone.
d) Depressing the menu key ( 11 ) three times.
12) VOX function
While the VOX function is active, the unit switches automatically
to transmit mode when the sound level at the microphone ( 9 ) is
above a certain threshold. If the voice loudness at the microphone
( 9 ) 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 acti-
vate the VOX function and how to work with it:
❍Depress the menu key ( 11 ) four times, until the VOX
function ( = VOX ) flashes in the LCD window.
❍Now you can adjust the VOX sensitivity. Press the up key ▲
( 3 ) to increase the VOX sensitivity for one step.
❍Press the down key ▼( 4 ) to decrease the VOX sensitivity
for one step.
Pressing the keys for one second will make the VOX sensitivity
change quickly. The bar meter in the lower right side of the dis-
play, which indicates normally the volume level adjustment,
shows the currently adjusted VOX sensitivity. The height of the
confirmation tones doesn’t depend from the currently adjusted
VOX sensitivity. At the end of the adjustment range two high sig-
nal tones are audible. If the VOX sensitivity is set at the lowest
possible value, so that no more bar is visible, the VOX function is
deactivated. To return to the normal receiving mode, you have 3
options:
English
20 21

a) Depressing the enter key ( 6 ).
b) Depressing the PTT key ( 12 ).
The unit will transmit immediately.
c) Depressing the menu key ( 11 ) two times.
If you adjusted the VOX sensitivity at a too high level in a noisy
area, it is possible that the transmitter starts to work unwanted. By
depressing two times the enter key ( 6 ) the transmitter can be
inhibited for 4 seconds. During this time you have time to reduce
the VOX sensitivity.
13) Second counter function
Depress the menu key ( 11 ) five times, until two zeros are
flashing at the position of the channel number in the display.
Press the up key ▲( 3 ) to make the numbers appear constantly
and count upwards in the rate of a second. Press the down key
▼( 4 ) to stop the counting and to make the number flash again.
By depressing the enter key ( 6 ) the counter will be reset to
zero. By pressing any key or at the arrival of a reception signal,
the unit will return to the normal receiving mode.
14) Charging of accumulators in the unit
The charger and the accumulators are not included to the set.
Never try to charge alkali cells. If you use rechargeable cells you
can charge them inside the McTalk 446 with the help of the
optional available charger item No. PR2023. Before charging
make sure, that 4 rechargeable cells of NiMH type are inside the
battery compartment, and that the unit is switched off. Then insert
the charger into a wall outlet ( 230 V, 50 Hz ). Then connect the
plug at the end of the cable into the 2.5 mm socket MIC/CHG ( 15 )
on the upper panel of the unit. The loudspeaker ( 7 ) gives a long
tone, and the display shows constantly the actual channel with
the currently adjusted volume level, and flashing the battery sym-
bol with both bars. The charging time amounts to about 14 hours
and in case of partially discharged cells about 6 hours. After the
charging time has terminated, you have to disconnect the charg-
English
er. The loudspeaker gives a long tone and in the display all sym-
bols disappear. The unit is switched off now.
Safety
The unit radiates in transmit mode RF energy. To reduce the
exposure at the lowest possible value, and to benefit as much as
possible of the features of the unit, you should take into account
the following advice:
In transmission mode keep the unit in a vertical position at a dis-
tance of 2 to 3 inches from your face. Keep the antenna at a dis-
tance of at least 1 inch away from your head and your body. If you
carry the unit on your body and if the unit is in transmit mode,
make sure that the antenna is kept at a distance of at least 1 inch
away from your body.
Service
The condition of the batteries must be tested from time to time.
Worn out batteries must be removed from the unit immediately.
They can leak and damage the device. The batteries should
always be replaced as a complete set
Worn out batteries do not belong in the waste bin, but must be
returned to a suitable collecting depot or to a special dealer, for
the sake of the environment.
There are no user adjustable or user serviceable parts inside the
radio. The casing must not be opened. Independent repairs or
adjustments must not be carried out, since each modification or
unauthorised intervention will immediately cancel all and any war-
ranty or repair claims, they are also likely to result in nonconfor-
mity Tto ETS regulations which will render the set to become ille-
gal. In the event a defect becoming apparent, contact a properly
equipped and authorised TEAM dealer or TEAM directly
Conformity
The transceiver TEAM McTalk 446 complies with the rules of the
European Directive R&TTE and meets the European
Telecommuni-cation Standards ETS 300 296 & ETS 300 279.
