LED INDICATOR
A tri-color led indicator has been added on your radio to visual
communicate the following status.
Lights red: while transmitting.
Lights green: while receiving.
Flashes red: when the battery power is low, once per 2 second when
battery charge is under the 5% and once per second when it’s less than
2%.
Orange led blink: an unattended event is available (alert call, message
received, etc.).
These functionalities can be disabled on your dealer shop. Please ask to
your dealer if you wish no lights on your radio.
SWITCH ON/OFF AND VOLUME SELECTOR
Turn clockwise to switch ON the transceiver. Rotate to adjust the volume.
To switch OFF the transceiver, turn it counterclockwise fully.
Your SDR radio has four additional functionalities, which can modify the
current volume status:
Minimum volume level: by programming, your radio can define the
minimum audio level, even when the volume knob is completely close.
On this way, it never loses a call due to low volume.
