Transmitting time limitation (Time Out Timer)
The transmitting time limiter (TOT) prevents continuous transmission and
therefore prevents channels being occupied. The transmitting time limiter
(TOT) can be adjusted in increments via the software. The expiration of the
specified transmission time is signalled by a reference tone. The user can
interrupt the signal by releasing the PTT button. If the transmitting time limiter
is exceeded, the transmission is interrupted automatically. The maximum
transmission time in the TOT mode is 3 minutes.
Battery status display
Press the pre-programmed battery status display button and the walkie-talkie
will announce the battery status acoustically („1", „2", „3", „4").
Battery saving mode
Turn on the battery saving mode via the optional software in order to reduce
the unit's power consumption during standby operation. The radio unit auto-
matically changes to this mode after approximately 10 seconds if there is no
activity. The mode is deactivated as soon as the unit receives a signal or the
user conducts an activity.
Low battery status warning
The red LED display flashes if the unit's battery status is too low for trans-
mission. After an audio signal is sounded three times (after 30 seconds in
each case), transmission is terminated. The battery must be recharged or
replaced.
Control call
The control call is transmitted by pressing a pre-programmed button. The
recipient receives a warning tone over a preset time period. The control
call can be terminated by pressing any button. Otherwise the radio unit will
automatically change to the emergency call mode that was programmed to
begin with.
CTCSS/DCS pilot signals
The analogue/digital CTCSS/DCS pilot signals serve for the formation of
groups and the avoidance of unwanted activities on the same channel. If a
pilot signal has been programmed and a message is transmitted, only one
channel opens for the recipient if he/she has programmed the same pilot
signal.
