3.2. Navigation / Channel encoder ("NAVI / Ch").
This rotary encoder allows the user to browse through the different menus of
the OLED multifunction screen. Turning it changes the selection among the
options presented, moving the highlighting up and down. When the encoder
is turned clockwise, the option selected is moved down, and turning it anti-
clockwise, the option selected is moved up.
Pressing its button is equivalent to ENTER, validating the highlighted
selection at that moment.
This rotary encoder has a second use. If the the second, optional channel (coordination COOR)
is activated and no menu is being presented on the display, pressing the encoder will make the
user interface change between PGM and COORD.
Tha modification of any of the parameters pertaining to the selected channel does not affect the
selected operation of the other channel; if we are modifying the configuration for program
(PROG), the status for coordination (COORD) will remain the same, with its communication,
operating modes, etc. unaltered.
The active channel is clearly indicated by the "PROG" and "COORD" labels located between
the vumeters. When a call or communication is established in the channel that is not active, the
label will blink while the other remains steadily lit.
3.3. Vumeters.
The unit is equipped with two stereo vumeters. From
above, the first one is indicating the level of the TX
signal. The second indicates the level of reception,
RX. If the unit has the second optional coordination
channel activated the vu meters will follow the "NAVI /
Ch" encoder and will display the levels corresponding
to the active channel and with the labels "PROG" and
"COORD" between the vumeters and as explained
above.
Each of the 4 vumeters consists in 2 bars of 20 LEDs each. From right to left, the three first
LEDs are red followed by four orange coloured ones. The remainders of the LEDs are green.
The scale applied has higher resolution around the transition between green and yellow colors.
Please note that the presence of audio is denoted at -36 dBV when the first green LED is
illuminated. Transition from green to yellow is at 0 dBV, from yellow to red is at +7 dBV and,
when all 3 red LEDs are on, displayed level corresponds to +13 dBV or higher.
