Battery charging is performed as follows:
1. Connect a power unit (PU)3,8/12 to a charging unit (CU-2);
2. Switch a power unit.
3. Switch on a charging unit to the socket 220 V 50 herz, observing the necessary measures of
electrical safety;
4. Leave PU3,8/12 in such a condition for 8 – 10 hours.
The process of charging starts automatically after a connecting a charging unit to the electric
mains:
First phase of battery testing comes. This phase lasts about 10seconds while the red LED on the
case of a charging unit is flashing.
After finishing a test phase a process of charging PU 3,8/12 is switched on, which is indicated
by a constantly gleaming. After the end of a charging process a green LED starts to flash, a red LED is
not indicated, and a power unit turns to a mode of maintaining a charged status of the battery (trickle –
charge). A battery is charged but it may be connected to a charging unit for unlimited time.
To preventively discharge the batteries (in order to decrease “memory effect”, hold the button
PRESS for 2 seconds. After the process of discharging the battery, which may last several hours, a
charging process is switched on automatically.
If a red LED goes on flashing after the end of a test phase which lasts 10 seconds, and does not
turn to a steady shining light, indicating a charging process that signifies that there is a malfunction of
a battery and that the latter should be replaced by another one (from the accessories ZIP-0).
8. Routine
Repair.
Routine repair is performed by a company manufacturing. To perform a routine repair a
defective unit of the device is sent to a company manufacturing with a detailed description of the
detected malfunctions. If the defects of the unit cannot be pin – pointed, the whole device is sent for
repair.
9. Storage
Storage conditions of a device are to meet the requirements of GOST
В
9.003-80 and GOST
