use.of.the.internal..transmitting.antenna.or.with.the.extra.accessories.involved,.for.example,.the.

WARNING! ENERGY SAVING!
All operations with output voltage (current and power) under connected load, lead to
the changes of the energy consumption and consequently, “life-cycle” of the autonomous
power supply. Watch the indicators of the power supply voltage “U” and absorbed
current “I” in the electrical power supply field, so that there is enough time to perform
utility location. In order to save energy, operate the device at the minimum sufficient load
power. Always use “economy” pulse mode “Pu” when applicable. The operation breaks
help to partially restore the capacity, therefore, net operating time with interruptions is
always more than time of continuous operation, given all other conditions remain equal.
The fall of environment temperature at the autonomous battery power supply has an
adverse effect on the “life-cycle” of the power supply set (especially crucial at sub-zero
temperatures). Always have a backup set of batteries.
