On Menu mode, all display is used for the related Menu application, for
example, to edit a text message or to check the RSSI or RSDI.
4.1. ICONS
Top area of the display is reserved to display icons. These icons
represent radio status and are dynamically located on the icon area of
the display.
RSSI: Receive Signal Strength Indicator. Special care must be taken
when the channel in digital mode because this indicator shows the RDSI
(Receive Digital Signal Indicator) as average digital signal quality related
to the BER (Bit Error Rate) on the channel and not the RSSI level.
In transmit mode this icon shows an antenna and a letter indicating
the real power transmit.
Power: shows the transmit power Set. (L)ow, (M)edium,(H)igh,(A)uto.
Speaker: this Icon represents the presence of audio in the radio
Speaker (External or internal), then the Icon implies the radio is
reproducing receive audio (Analog or digital) on the speaker. This is
only for receiving audio not for generated tones or radio announces.
Analog mode: this Icon shows to the user if the current channel is
an analog channel.
Digital mode: this Icon shows to the user if the current channel is a
digital channel.
: Hybrid mode: This icon appears when the radio is operating on
analog mode over a digital channel.

Page 13
GPS: Shows the GPS status. If the GPS is enabled, then this icon
appears on the screen. After the dish, the GPS status is qualified. A
small cross means there is no attached GPS or the radio is not receiving
information from external device, meanwhile if the GPS information is
accurate, a scaled bars represent the amount of satellites used to fix
the GPS service: 1 bar, less than 4 satellites. 2 bars appears if the
quantity of satellites used to fix are between 4 and 8 satellites. If 3 bars
are shown, more than 8 satellites fixed.
Envelope: New message has arrived and not read yet.
Scan: Shows to the user that the radio is in scan mode.
USB: This icon is shown when the radio has a locked connection to
any USB host or an USB charger.

decreases the squelch level for all the channels in the radio.
By programming, the squelch level of each channel can be adjusted
individually.
RSSI/RDSI: (Receive Signal Strength Indicator/ Receive Data Signal
Indicator): Working on analog, voice report and display of current RSSI
level. Displayed information is momentary. If you wish to read it
continuously, please go through radio menu.
If the radio is working on any Digital Mode the reported information is
