please remove larger particles by blowing on the lens. For
subsequent lens cleaning we recommend the use of the
enclosed cleaning cloth. In the event of hard-to-remove
grease spots, finger prints or dried-on drops of water,
breathe slightly on the lenses or moisten them with a damp
cloth and clean cautiously. Make sure that the cleaning
material is always kept clean. Dirt in the cloth may cause
damages to the lens coating.
8.1 Replacing the battery
(HELIA RF & HELIA RF-M)
Check how much charge is left in the battery. Seeing a
flashing battery symbol when the instrument is switched on
indicates a low battery. From the time the low battery
indicator first starts flashing, there is sufficient power for
around 100 more measurements.
Replacing the battery:
Open the battery com-
partment cap on the
central focusing (HELIA RF)
or on the eyepiece (HELIA
RF-M). Remove the dead
battery. Insert a new CR 2
battery, making sure that
the poles are correctly
aligned (see markings inside com part ment). Use leak-
proof batteries only.
Warning:
Do not use recharge able
batteries ! Finally, screw the battery cover back on.
