2 ACCESSORIES 3 BATTERY PACKS ‘ Accessory attachment ‘ Battery pack replacement D Antenna Before replacing the battery pack, push [POWER] for 1 sec. to turn the power OFF. Attach the antenna onto the transceiver as illustrated at right. Keep the jack cover attached when jacks are not in use to avoid bad contacts. • Push the battery release forward, then pull the battery pack upward with the transceiver facing you.
3 BATTERY PACKS BATTERY PACKS ‘ Battery caution ‘ Battery charging • CAUTION! NEVER short the terminals of the battery pack (or charging terminals of the transceiver). Also, current may flow into nearby metal objects such as a necklace, so be careful when placing battery packs (or the transceiver) in handbags, etc. Simply carrying with or placing near metal objects such as a necklace, etc. causes shorting. This will damage not only the battery pack, but also the transceiver.
