Battery life
The approximate battery life (operating time) as
shown below is calculated under the following
assumptions:
•
Power save setting: Auto (Short)
•
Duty cycle: TX : RX : Standby = 1 : 1: 8 (based on
operating style)

battery life�
NOTE: BE SURE
to replace the battery pack with a
new one approximately five years after purchasing,
even if it still holds a charge� The material inside
the battery cells will become weak after a period of
time, even with little use.
The estimated number of times you can charge the
pack is between 300 and 500� Even when the pack
appears to be fully charged, the operating time of
the transceiver may become short when:
• Approximately five years have passed since the pack
was manufactured�
•
The pack has been repeatedly charged�
TIP:
Keep the battery terminals clean� It’s a good
idea to occasionally clean them�
