generating small signal. Since that, extra attention should be paid. We
recommend using it only for comparison.
4.Test Preparation
KC908 is equipped with two RF input/output channels, and it's capable
of testing spectrum and field strength. Preparations are different as for
different test.
4.1 Battery and Charging
The battery amount left would be displayed on the top-right part of the
screen, and the user should check it before any further operation. If the
battery voltage is higher than 8.2V, it means the battery is fully charged. A
battery voltage lower than 7.0V indicates the available operating time is less
than half an hour, the machine must be charged.
The rate the battery is consumed differs in different functions. After fully
charged, the typical endurance time is shown below.
