6.4 Transmit (Talk) Operation
IMPORTANT!
Please keep radio discipline!
Transmit only on a clear channel.
Since 'Transmit Blocking' is normally activated (refer to SET-UP)
transmitting is not possible on a busy channel.
Care for an all-round obstacle free antenna location; the called
station should be within "line-of-sight" distance.
Never place the radio such as the antenna gets very close to, or
touching, exposed parts of the body, especially the face, shoulder
or the eyes.
The radio is equipped with a transmit time out timer (2 minutes).
This is used to limit the duration of calls and to guard against
accidental PTT locking.
If the display mode shall be changed: Push once or twice the
MD
button.
If the USE frequency shall be changed: refer to
6.2 Turning ON - Selecting
Frequency/Channel Name - Volume
.
Transmitting is normally only possible on a clear channel (no communication
audible).
If you have to transmit (e.g. emergency case) although the channel is busy, the
"Transmit Blocking" circuit may be turned OFF by pushing the
SQ
button.
Press and hold the PTT (Push-To-Talk) key. Talk in a loud, clear voice with the
microphone opening 2 to 4 cm (1" - 2") from your lips. Make each transmission as
brief as possible. As long as the PTT key is pressed the
Transmit Indicator
at the
display appears!
Release the PTT key to end transmission and to clear the channel for reception; the
Transmit Indicator must disappear. Switch Squelch ON again, if necessary.
The radio is equipped with a transmit TOT time out timer. This is used to limit the
duration of transmissions to 2 minutes. When the transmitter is keyed continuously
longer than 2 minutes the display of the
FSG 90(X)
starts flashing and transmission
is disabled.
If you have to make calls longer than 2 minutes shortly release the PTT key and
press again.
Should the TOT disable the transmitter accidentally (e.g. stuck PTT key) and you
have to transmit
turn radio OFF and ON again
. This allows another 2 minutes to
transmit.
