3 Connect the barrel plug on the DC cable to the DC IN jack of the transceiver.
• While a DC power supply is connected with the DC IN jack, the transceiver
automatically initiates charging the PB-45L battery pack.
Note:
X If the DC power supply voltage is below 12.0 V DC, you may not be able to charge the PB-45L
battery pack.
X The supply voltage must be between 12.0 V and 16.0 V to prevent damaging the transceiver.
If the input voltage exceeds approximately 17.5 V, the transceiver automatically turns OFF.
