11Charging the Battery PackCharging the Battery Pack using the Battery Charger (SAD-25B)Using the supplied battery charger (SAD-25B), it takes about 9 hours* to charge theSBR-14LI battery pack fully.*Depending on the battery status, the charging time might be increased1. Turn the transceiver OFF to install the battery pack.2. Referring to the figure at the right, connect thebattery charger plugs.When the battery is being charged, the TX/BUSYIndicator lights red, and “CHGING” is dislapyed.3. When charging is completed, the display willchange to indicate “CHGFUL” and the TX/BUSYIndicator will light green.EXT DC INjackBattery chargerSAD-25B(supplied) When charging is completed, the charging is automatically ended. If “CHGERR” appears on the LCD during the charging and the battery pack is notcharged after a lapse of 10 or more hours, stop charging the battery pack immediately.The battery pack is presumed to be at the end of its service life, or defective. In this case,replace the battery pack with a new one. Charge the battery pack within the temperature range from +41°F to +95°F (+5°C to+35°C).Charging the Battery Pack using the Rapid Charger (CD-41)For details on the Rapid Charger (CD-41), see Optional CD-41 manualApproximate Operating Time and Remaining Charge Level IndicationApproximate operating time for the transceiver with the fully charged battery pack ornew AA alkaline batteries is as follows:Band in UseDigital: OFFBattery packSBR-14LIBattery packFNB-101LIBatteryFBA-39Amateur Band144 MHzBand Approx. 10 hours Approx. 5 hours Approx. 12 hours430 MHzBand Approx. 8.3 hours Approx. 4.1 hours Approx. 11 hoursAM Broadcast Band Approx. 20 hours Approx. 10 hours Approx. 14 hoursFM Broadcast Band Approx. 20 hours Approx. 10 hours Approx. 14 hoursBand in UseDigital: ONBattery packSBR-14LIBattery packFNB-101LIBatteryFBA-39Amateur Band144 MHzBand Approx. 8.8 hours Approx. 4.4 hours Approx. 12 hours430 MHzBand Approx. 7.6 hours Approx. 3.8 hours Approx. 11 hoursThe battery charge level calculations are based on an operating cycle of: Transmitting 6seconds (5 W): Receiving 6 seconds (VOL Level 16): Stand By 48 seconds (RX SAVE1:5)The actual times the transceiver will operate as indicated in the above table, varies de-pending on use, conditions, ambient temperature, etc.
