NEVER store the rangefinder on the floor near heaters.
The rangefinders are arranged in the storage room so that steel
and iron objects are at least 2 m away.
To prevent demagnetizing of the needle, the latter should be
aligned with the magnetic meridian. To achieve that, store the
packing cases so that the arrow marked on top points to the
North.
Charged batteries may be stored together with the rangefinder
unit for up to three months.
13.3. The rangefinder placed in short-term storage (up to 3
months) is subject to inspection as directed in Section 10.5 and
Long Term Storage as directed in Section 12.
13.4. If the rangefinder is to be stored for over three months,
discharge the batteries as directed in Section 15.
14. SHIPMENT
14.1. The rangefinder unit is to be shipped in wooden package
AEP 42.83.368. The rangefinder can be shipped by any transport
means. During shipping, it must be protected against
precipitation, spray and sun rays.
14.2. Before transit, the rangefinder must be closed down and all
its components are secured in the metallic package AEP
42.86.184 (Fig. 7). All locks and hinges of package and case are

14.3. When carrying the rangefinder in a truck, stow it in the
