4. INSTRUCTIONS FOR OPERATION
4.1. Indicators are recommended to be operated with 91 kOhm±5% load resistors
and cathode scan cycle repeat frequency of 500-1000 Hz with duty ratio of 64
and corresponding anode voltage pulse duration (τia).
Scanning may be ceased for no longer than 5[indecipherable] with τia over
15 us up to 10 pcs of illuminated but not addressed elements may appear with
brightness of at most 25% of the brightness of the adjacent addressed display
element.
-6-
95-110 kOhm load resistors may be used in anode circuits with corresponding
decrease in brightness.
4.2. Display elements may be turned on in any sequence and combination.
4.3. In order to simplify control of a compound screen, at most 4 indicators
may be connected in series via cathodes or anodes.
4.4. Time to readiness may be decreased by increasing the number of
simultaneously enabled elements and (or) increasing brightness to 200 lux.
4.5. Indicator may be operated for a short time at a lowered temperature
of minus 20°C for a continuous duration of no more than 30 min. Total time of
operation at minus 20°C must not be more than 1 hr. Indicator may be operated
with anode power supply voltage of 420 V for 100 hr during minimum time before
failure. Given the above, up to 10 pcs illuminated elements are permitted with
brightness of up to 25% of the brightness of the adjacent addressed display
element.
4.6. In order to increase image contrast in conditions of increased
background illumination, it is recommended to use a dark matte grid.
4.7. Operating orientation of the indicator is horizontal; slanted and
vertical may be used with horizontal orientation of cathodes.
4.8. Cooling is passive.
4.9. In equipment the indicator (with horizontal orientation of cathodes)
is mounted with nuts attached to bolts on the back side of the indicator
using rubber gaskets with thickness of 2-5 mm or rubber washers with thickness
of 2-6 mm and diameter of no less than 10mm, which are used for alignment
of equipment faceplates. Screws may be tightened with at most 0.05-0.1 kgf/m
of torque.
In mounted position indicators may not move or apply pressure to each other.
During installation indicators may not be hit on any surface.
4.10. Indicator is connected by soldering contact pads. Before soldering
it is recommended that contact pads be cleaned with rags.
Soldering to contact pads must be performed with ПОССУ-61-0.5 [61% Sn,
0.5% Sb, Pb balance--transl.] solder with soldering iron tip temperature
of (260±10)°C. Time of continuous heating no higher than 2 s. Interval between
heating no less than 3 s. Any contact pad may be heated no more than 3 times.

5. STORAGE
Minimum shelf life of indicators when stored in a heated storage area or
in all storage areas of indicators integrated into protected equipment or
stored in a protected spare parts kit is 15 years.
If indicators are stored in factory packaging or integrated into
non-protected equipment, or contained in a non-protected spare parts kit,
under a shed or in an open area, minimal shelf life is provided in the table.
Minimum shelf life
Place of storage in factory in non-protected equipment
packaging or spare parts kit
-------------------------------------------------------------------------------
Non-heated storage area 10 10
Under a shed 10 7.5
Open storage area storage not 7.5
permitted
When storing indicators in conditions of a non-heated storage area,
under a shed or in an open area during a part of minimum shelf life,
the remaining minimum shelf life can be determined by the difference between
minimum shelf life in conditions of a heated storage area and a product of
coefficient of reduction of minimum shelf life K_nonheated_stor = 1.5;
K_shed = 1.5 - 2; K_open_area = 2 by actual time of storage in a non-heated
storage area, under a shed or in an open area.
6. WARRANTY
Manufacturer guarantees that the quality of each indicator satisfies
requirements of ОДО.339.519 ТУ given that the consumer follows requirements
and rules of storage, transport, installation and operation given in
ОДО.339.519 ТУ.
Warranty period is equal to minimal shelf life described in section 5.
Warranty operating time equals minimum time before failure described
in section 2.3, up to warranty period. Warranty period starts at date of
manufacture, and for indicators that underwent repeat checks, from the date
of repeat check.
7. RETURNS
In case of failure of the indicator, it must be returned to the manufacturer
with the following details filled in:
