Low Battery Indication

As you battery discharges during use, the voltage will
gradually become lower. When the “

” begins

blinking on the LCD dis-
play, the battery pack
must be recharged before
further use.

Avoid recharging Li-Ion batteries before the “Low Bat-
tery” indicator is observed, as this can degrade the
charge capacity of your Li-Ion battery pack. Yaesu
recommends that you carry an extra, fully-charged
pack with you so you will not lose communications
capability due to a depleted Li-Ion battery.
This “deep cycling” practice will help to maintain
longer overall battery life after many recharging cycles.
