Busy Channel Lock Out; Transmission Power - ALAN Electronics HP 106 Manuel D'utilisation

5.6.b Busy Channel Lock Out
The radio might be programmed with the Busy Channel Lock Out
(BCLO). In this condition the PTT button is disabled during the reception
of radio signals. For such reason, if you are not able to transmit while you
are pressing the PTT button (the status LED is not glowing red), release
the PTT button and verify if the channel is actually free (the status LED is
turned off).
Depending on the programming, the BCLO can work either when it
finds any signal or in case of a signal with a specific CTCSS/DCS
signaling.
5.6.c Transmission Power
Your ALAN HP106/HP406 can transmit with two power levels according
to the distance of your party station(s). The low/high power channels are
preset during the programming and cannot be modified by the user. We
strongly recommend to use low power when possible: you will extend the
life of the battery and you will reduce the risk of interference with stations
not belonging to your radio network which could share with you the same
channel.
In case of low battery level, the unit will then automatically revert to
low power in order to help to extend the battery's operational life. In
this case, two short beeps (acoustic signals) will be heard before
transmission and one during reception.
