25PreparationPreparing the Battery Pack/External Power SupplyRemark Approximate hours are estimated assuming that the transceiver is operated under thefollowing conditions. The operation time that this transceiver can be actually used variesdepending on use conditions, ambient temperature, etc.• When the GPS function is deactivated.• LAMP MODE SAVE ON (always LAMP OFF)• When the transceiver is repeatedly operated by high-power transmission for 6 secondsand reception for 6 seconds, and standby for 48 seconds with an amateur ham radioband selected.How to Use the Battery Case (FBA-39)The optional battery case (FBA-39) allows 3 AA Alkaline batteries to be used to powerthe FT2DR/DE transceiver.TipWhen the battery case (FBA-39) is used, the power output level may be selected from:Low Power (L1): 0.1 WLow Power (L2): Approximately 0.8 WNote that Low Power (L3) and High Power are not available.1 Open the cover.Lift up the lower right corner of the cover as indicated by thehand pointer in the illustration.2 Place the alkaline batteries in the battery case.Caution Use 3 alkaline batteries. Pay attention to polarities (+ and −)of the alkaline batteries.3 Close the cover.Push the four corners of the cover firmly to close it tightly.TipWhen the battery charge is low, lights on the LCD. When thebatteries are almost exhausted, blinks on the LCD.Cautionsy Lithium/Manganese batteries cannot be used with the FBA-39 batterycase. Rechargeable AA batteries cannot be used, either.y Do not mix new and old batteries. The service life of new batteries maydecrease.y If you do not use the transceiver for a long period, remove the batteriesfrom the battery case.y If the terminal or electrode of the battery case is dirty, the transceiver canmalfunction due to poor contact, resulting in overheating or explosion.If the terminal or electrode gets dirty, clean it using a dry cloth or cottonswab.
