To insert the belt clip, push the notch of the clip into the notch on
the rear panel of the unit. Then push the clip towards the unit’s
bottom side until the belt clip latches.
Inserting the batteries
To insert the batteries, turn the rear panel
toward you and remove the belt clip if neces-
sary. The battery compartment lid ( 8 ) is locat-
ed right below the type plate. Push down the
latch of the lid and pull it toward you.
Now insert 4 AAA ( = Micro ) alkaline batteries or
the optional accu-pack of the Twin Power Pack 508 into the bat-
tery compartment according to the indicated polarity signs.
To close the battery compartment ( 8 ), place the guide pins, locat-
ed at the bottom of the battery compartment lid, into their holes.
Next, push the latch against the unit until it snaps in.
Operation of the TEAM TeCom-508
1) To Turn the Unit On/Off
To turn on the unit, depress the On/Off key ( 14 ) for about 1
or 2 seconds. Two short receipt tones can be heard from the
speaker ( 7 ). During the short initial self-test, which takes approx-
imately 1 second, all symbols can be seen on the display. Now
the unit is in receive mode.
To switch off the unit, depress the On/Off key ( 14 ) for about
1 or 2 seconds. A long tone can be heard and all symbols disap-
pear from the display. The last settings remain in memory.
2) Battery level indicator
The battery symbol in the lower left corner of the display indicates
the battery level. As long as both bars are visible inside the icon,
the batteries are sufficiently charged. If the supply voltage drops
below 4.4 V, the left bar disappears. If the supply voltage drops
below 4.2 V, the other bar disappears also, and the battery symbol
English
starts blinking and a melody can be heard every 14 seconds. That
means that you have to change or charge the batteries. The unit
will automatically shut off if the supply voltage drops below 3.8 V.
The TeCom-508 is equipped with a battery-saving-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-saving-function starts
automatically. While this function is active, the unit checks the
actual channel for incoming signals in regular intervals. The cur-
rent consumption in the power down mode drops down to 13 mA.
If you don’t use the unit it is better to switch it off. Should you not
use the unit for a longer period of time, we recommend you to
remove the batteries.
3) Volume level adjustment
The bar meter in the lower right corner of the display shows the
current volume level. Press the up key
▲
( 3 ) to increase the vol-
ume 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 pitch of the confirmation tone depends on the current
volume level. The limits of the volume range are indicated by two
high signal tones.
4) Disabling the noise suppression
The receiver is equipped with a circuit ( squelch ) that mutes the
receiver if there is no station available on the actual channel to
reduce the noise. If a signal is received, the squelch immediately
turns on the speaker, so you can hear the station. In case the
squelch lets signals pass, the LED turns green and the symbol
BUSY, to the right of the battery symbol, appears and indicates
that the channel is occupied. The squelch function can be dis-
abled, with the monitor function, to hear weak stations that are nor-
mally suppressed by the squelch. To turn off the noise suppres-
sion, press the monitor key M ( 10 ). The symbol ( = BUSY ) will
appear in the display. If there is no station on the actual channel,
