5.4. Measurement of range to the last target
If a target to be measured is overlapped by close targets, the signals from which
come to the rangefinder, and there is no object within the transmitter beam
behind the target (i.e. the reflected signal from this object does not come to the
rangefinder), then a range to such a target is the easiest to be measured in the
last target measurement mode (the L mode).
Set the operating mode switch to the L position and make ranging according to
5.2.
5.5. Switching-off
The handle of the power supply switch should not be left in the ON position
for a long time since in this case the battery is quickly discharged. That's why
the rangefinder supply should be switched off on completion of rangings.
6. MAINTENANCE
6.1. General
It is prohibited to disassemble the rangefinder.
6.2. Operator's maintenance duties (preventive maintenance)
The necessary maintenance of the rangefinder includes execution of the
following operations:
1) in case of detection of damages, faults or performance degradation, inform
the manufacturer;
2) in case of contamination, wipe the optical surfaces, the housing, the control
handles of the rangefinder with the cloth from the Accessory set;
3) if the silica gel colour changes from blue to pink (in this case the silica gel
is saturated with moisture), replace the silica gel in the desiccator after prior
heating the replacement silica gel from the Accessory set until it becomes blue;
4) carry out charging the accumulator battery (when the battery discharge
indicator lights (see Fig. 5).
Carry out charging when the ON supply tumbler is switched off in the
following manner:
- set the charged accumulator battery into the rangefinder;
- insert the charger into the socket;
- connect the charger to the rangefinder through the plug to connect the cable
of external supply =12 (see Fig. 2). In this case the (Charge) indicator on the
