BATTERY CHARGING (FOR ONLY ON-BOARD USE)
BE SURE to replace the battery pack with a new one approximately
five years after manufacturing, even if it still holds a charge. The in-
side battery material will become weak after a period of time, even
with little use. The estimated number of times you can charge the
battery is between 300 and 500.
Even when the battery appears to be fully charged, the operating
time of the transceiver may become short when:
• Approximately five years have passed since the battery was manufactured.
• The battery has been repeatedly charged.
