FT-411 MKII OPERATING MANUAL 9Accessories & OptionsNC-29 5-hour Quick ChargerThe NC-29 is a universal battery charger with quick and trickle charging modes for theFNB-11H, FNB-12, FNB-14 and FNB-17 Ni-Cd packs. The quick mode is automati-cally selected initially, to bring the battery pack up to full charge as fast as safely possibleusing an internal timer. Three LED indicators show elapsed charging time after 1, 3 and 5hours. The charger then automatically reverts to the trickle mode (green LED indicator), toprevent self-discharge. The quick mode recharges a completely discharged battery in about5 hours, depending on temperature.CAUTIONWhen using the NC-29, do not remove and then replace a battery from the chargerwhile it is charging, as this will reset the timer and may then overcharge the battery.PA-6 Mobile DC-DC Adapter/Charger for FNB-14 and -17The PA-6 is a DC-DC adapter for use when operating the transceiver mobile, and forcharging the FNB-14 and FNB-17 Ni-Cd battery packs. The PA-6 recharges a completelydischarged FNB-17 in about 15 hours, or trickle charges an FNB-14 (to full charge inabout 35 hours). Care must be used to avoid overcharging the batteries, as the PA-6 doesnot include a timer. The PA-6 cannot be used for charging the FNB-11H or FNB-12, asthe charging voltage is too low.Use with 12-volt negative ground electrical systems only.SPEAKER/MICROPHONESThe MH-32A2B and MH-34C2B Speaker/Mics and MH-37B2B Earpiece/Mic can be used toincrease operating convenience and extend communications range and signal strength.Each is equipped with a dual plug connector which mates with the EAR and MIC jacks onthe top panel of the transceiver, disabling the internal speaker and microphone. The cableallows the transceiver to be left clipped to your belt, or to be held overhead above obstruc-tions for improved performance, if required. For mobile operation with the MMB-32AMobile Hanger, the transceiver can be left in the Hanger during operation.A Speaker/Mic can be held close to your ear during reception; or anexternal earphone canbe connected via the Speaker/Mic plug, attenuating audio from the speaker in the Speaker/Mic. To transmit just hold the Speaker/Mic close to your mouth and close the PTT switchon the microphone (or on the cord of the MH-37B2B).
