3.5 Battery Life Guidelines
• New batteries should be fully (trickle) charged
and fully discharged several times to acheive 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 trans-
mitting continually than if it is just receiving.
Additionally, if the radio is set to High Power (5
watts*), the power drain will be considerably
greater than if transmitting on Low Power (1 watt*)
* Standard power settings.
