Appendix D eRadio FAQ
Failure Description Cause Analysis Solutions
Failing to power on

Unreliable power cable
connection (external
power supply);

The positive and
negative poles reversed
(external power supply);

Battery exhausted if
used

If external power supply is
used, connect to the power
cable correctly, with the
rated working voltage of
DC12V;

Wiring based on the correct
positive and negative poles;

For battery power, charge in
time; while powering on,
long press the power button
for 1 second or so
The configuration tool
cannot read or set up
parameters

Incorrect serial port
parameter configuration;

The existing serial port
for communication
occupied

Select the serial port
number, serial port baud
rate, 8 data bits, 1 stop bit,
no odd-even check, no data
flow control correctly;

Replace the existing serial
port number
Failing to sending data

Inconsistent
communication
parameter configuration
of the
receiving/transmitting
terminal;

No external antenna for
radio;

The battery voltage in
the threshold value of
forbidden voltage

Make communication
parameter configuration of
the receiving/transmitting
terminal consistent
(receiving/transmitting
frequency point,
communication protocol, RF
baud rate, operating mode);

If the radio has no external
antenna, select appropriate
antenna according to the
frequency band range;


value of low-voltage alarm
Replace the battery
The red power indicator
light flickers once in one
second The current power voltage
less than the forbidden
threshold value
Replace the battery
The red GPRS indicator
light flickers twice in one
second

