14.1 POWERING OF THE INSTRUMENT
SVAN 971 can be powered by one of following sources:
• Four AAA standard size batteries fitted internally. In the case of alkaline type, a new fully charged
set can operate more than 12 h (6.0 V/1.6 Ah). Instead of the ordinary alkaline cells, four AAA
rechargeable batteries can be used (a separate external charger is required for charging them).
In this case, using the best NiMH type, the operation time can be increased up to 16 h
(4.8 V/2.6 Ah)
• USB interface – 100 mA HUB.
SVAN 971 is delivered with four AAA alkaline batteries, but the you may also use AAA rechargeable
batteries.
The “battery” icon shows the condition of the internal batteries.
The instrument is not equipped with an internal charger; therefore, the rechargeable batteries can be
charged only after removal them out of the instrument.
To change or charge the batteries, switch
off the instrument, unscrew the bolt, take
off the black bottom cover of the
instrument and slide the battery tubes out.
Note: While changing the batteries, observe the correct polarity.
Powering the instrument from the USB interface is performed by
connecting its USB socket to the PC or other USB power source via the
SC 156 cable.
When the instrument is powered from the external power source the internal batteries are automatically
disconnected. Once disconnected from the external power source, the instrument will automatically
switch powering to the internal batteries.
Note: Use only high-quality USB cables, such as SC 156. Many poor-quality cables do not
ensure low resistance of the cable, thus disabling proper operating of the instrument.
14.2 MEMORY CARD EXTRACTION AND INSERTION
SVAN 971 is delivered with 4GB micro SD-card.
You may exchange it with the high capacity card (up to 32GB), but before insertion the card must be
formatted as FAT32.
Note: If you would like to use the card with higher capacity, consult this with the local
distributer.
