3.2. POWERING OF THE INSTRUMENT
The SVAN 948 is powered from four internal replaceable AA batteries. For the external power
operation an adapter should be connected to the Power socket located on the bottom cover of the
instrument.
The fully charged battery ensures more than 8 hours of the continuous work of the instrument (with
the backlight off). The operation time is decreased about 20 % with the backlight switched on. The battery
condition can be checked by means of the BATTERY function. It is also presented continuously (if the
internal AA batteries are used) on the display by means of the „battery” icon. In the case of using the
external power supply the “Battery” icon is not displayed on the screen but the red light “EX.POWER” is
on.

Notice: It is strongly recommended to use in this case as soon as possible the external
power adapter or replace the batteries. In the other case the instrument after a while will be switched off
by itself!
The backlight of the display and the keyboard can be activated by means of the <›

For saving the power of the battery, in the normal "day-light" operation it is recommended to keep the
backlight off. The user can set the TIMEOUT position in the BACKLIGHT sub-list of the DISPLAY list
which will cause the self made backlight switching off in the case when the keyboard is not used during
the last 30 seconds. If it happened the first pressing of any push-button switches the backlight on.
