3.8 Battery Life Guidelines
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 (5 Watts*), the power drain will be
considerably greater than if transmitting on
Low Power (1 Watt*).
