5.1 Pre-starting procedures:
1. Unpack the device. In order to install the battery, first make sure the
switch (1) is in the OFF position. Unscrew the battery house cover (5), and install 2
fresh AA batteries. Observe the correct polarity indicated on the housing. Screw the
battery house cover back on. Check the functioning of the device by switching it on
(rotate switch 1) and looking through eyepieces (4). (Make sure the lens cap is on
while operating during the daytime). If power supply and the batteries are O.K., you
will see greenish-lit screen. If the screen is not lit, check the batteries. Replace the
batteries if necessary. If everything works, now is a great time to fill the warranty card.
