NOTE:
AC power is recommended when using radios with the station. A 10-watt solar panel can be
used but days without sunlight and winter months with little sunlight should be considered.
The WS-PRO2 station comes with a 7 amp-hour battery that is NOT designed to handle deep
discharge. Discharging the battery below 11 VDC may require battery replacement. Below are
some examples of power calculations. Battery current consumption is based on discharging
the 7 amp-hour battery to 80% capacity (5.6 amp-hours). Discharging the battery past this
value could result in damaging the battery.

See your spread spectrum radio manual for changing radio settings.
Power usage example:
Polling the station once an hour and staying on line with the station for one minute consumes
approximately 0.388 amps over a 24-hour period. If the station were to lose power, it could run
for around 14 days (346 hours) before damaging the battery. A station with a 10-watt panel
would need at least one hour of sunlight every day to keep the battery charged.
