OTICES
The transceiver has been designed and engineered to
avoid possible hardware glitches. However, you may
notice the following symptoms when you operate the
transceiver. These symptoms are not malfunctions.
Operating Voltage
As stated in “SPECIFICATIONS” {page 122}, this
transceiver operates on 6.0 V ~ 9.0 V DC (battery
terminal) or 12.0 V ~ 16.0 V DC (DC IN jack). If you
find that the transceiver cannot be switched ON, or
“DC ERR” appears, the supplied power source may be
outside of the specified range.
In such a case, remove the DC power cable from the
transceiver immediately and confirm that the power
source voltage is within the specified range.
If you are using a variable DC power supply to operate
the transceiver, adjust the DC power supply voltage to
13.8 V DC. Considering the output power efficiency and
thermal characteristics of the transceiver, this is the
optimal voltage to operate the transceiver. If the voltage
at DC IN jack exceeds 14.5 V, the transceiver output
power is automatically reduced to “
” power.
Receiving Signals in Cities
When you receive signals in cities, the receiver’s entire
S-meter may light up without receiving any strong
signals. This happens when the RF amplifier in the
receiver is overloaded by strong interference signals
that are nearby.
