VX-6R OPERATING MANUAL10INSTALLATION OF FBA-23 ALKALINE BATTERY CASE (OPTION)The optional FBA-23 Battery Case allows receive monitoring using two “AA” size Alka-line batteries. Alkaline batteries can also be used for transmission in an emergency, butpower output will only be selectable 300 mW and 50 mW, and battery life will be short-ened dramatically.To Install Alkaline Batteries into the FBA-23 Slide the batteries into the FBA-23 as shown in the illustration,with the Negative [–] side of the batteries touching the springconnections inside the FBA-23. Open the Battery Pack Latch on the bottom of the radio. Install the FBA-23 as shown in the illustration, with the [+] sidefacing the bottom of the transceiver. Close the Battery Pack Latch on the bottom of the radio.The FBA-23 does not provide connections for charging, since Alkaline cells cannot be re-charged. Therefore, the NC-72B/C, E-DC-5B, or E-DC-6 may safely be connected to theEXT DC jack when the FBA-23 is installed.1) The FBA-23 is designed for use only with AA-type Alkaline cells.2) If you do not use the VX-6R for a long time, remove the Alkaline batteriesfrom the FBA-23, as battery leakage could cause damage to the FBA-23 and/or thetransceiver.LOW BATTERY INDICATION As your battery discharges during use, the voltage will gradually become lower. Whenthe battery voltage is becoming too low for reliable operation,the “ ” icon will blink on the LCD display, indicating that thebattery pack must be recharged before further use. Avoid recharging Lithium-Ion batteries before the “ ” indicator is observed, as thiscan degrade the charge capacity of your Lithium-Ion battery pack.INSTALLATION OF ACCESSORIES
