Preparing the Battery Pack/External Power Supply
Tips
• The SBR-14LI battery pack can be charged in approximately 9.0 hours using the external power
supply (approximately 5 hours to charge the optional battery pack FNB-101LI). If the transceiver is
turned on while the battery pack is charging, the charging time will increase slightly.
• If the transceiver is connected to the external power supply with the transceiver turned off,
"CONNECTED TO EXTERNAL POWER" appears on the LCD for about 20 seconds, and then
"BATTERY NOT INSTALLED" appears.
