Battery Life Guidelines
• New batteries should be fully charged
and fully discharged several times to
achieve full capacity.
To a large extent, the battery life will depend
on the usage, or Duty Cycle of the radio - i.e.
the battery will be drained much quicker if
the radio is transmitting continually than if it
is just receiving. Additionally, if the radio is
set to High Power (2.5Watts*), the power
drain will be considerably greater than if
transmitting on Low Power (1Watt*)
