assumptions:
•Power save setting: Auto (Short)
•Duty cycle: TX : RX : Standby = 1 : 1: 8 (based on
operating style)
The approximate battery life:

battery life�
NOTE: BE SURE to replace the battery pack with a
new one approximately ve 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 ve 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�
