its mount.
Begin speaking only after having pressed the PTT button and do
not release it until you have finished speaking, otherwise all or
part of your message will not be transmitted.
Do not yell! This does not increase the distance of transmission;
rather, your words come across as distorted.
Normally, a transceiver will not allow you to send and receive
simultaneously, so when you are speaking, others will not be able
to do so. Send your message within a reasonable time period so
as not to occupy the channel for very long.
Consult the following paragraphs for information on correct
transmission.
6.7.a Time Out Timer (TOT)
The radio can be programmed with an internal TOT (Time Out Timer),
which automatically forces your radio into reception mode if you have
been speaking for too long (time for this is determined in the program-
ming phase). If this happens, release the transmission button and
wait for a few seconds: the transmission functions of the radio will be
automatically restored. For further information, contact your vendor
or network administrator.
6.7.b Busy Channel Lock Out (BCLO)
Activation of this function impedes the use of the PTT button when
the channel is busy.
Depending on the programming, the BCLO can act when it picks up
any signal, or when a signal is coming from a specific CTCSS/DCS
signal.
This setting is not available by the end user. For further details,
please contact your radio network administrator.
6.7.c Selecting transmission power
Your transceiver can transmit with two different power levels, which
are predefined during programming, channel by channel. The display
will always show the power selected, using the following icons:
•
- high power
• - low power
1) Press the button to access the command menu, then use the
buttons to highlight the
Radio Param
option.
2) Press to view the available sub-menus.
3) Press the buttons until the sub-menu Power is highli-
ghted. The display will show the power level currently selected:
Hi
(high power) or
Lo
(low power).
4) Press to select the desired power level.
5) Exit the sub-menu by pressing the F4/ESC button, then press it
a second time to exit the main menu and return to the standby
screen.
