Operation Manual

AVR SLIM LCD

1. The switch is off.

2. There is no power in the 

socket.

3. The bimetallic circuit- 

breaker 

i

 has activated.

The AVR is out of order.

Input voltage is very unstable.

• 

When  the  mains  voltage  exceeds  the  allowable  rate  (lower  threshold  is  140  V,  upper  threshold  is 

260 V) the LED 

c

 illuminates, the AVR disconnects the load automatically and the LED 

d

 displays 

“L” or “H”.

Attention! It is recommended to switch off the AVR and every connected consumer-device 

when the power supply is dropped.

8. PAUSE FUNCTION

• 

The Pause mode feature is designed to protect equipment in case of frequent drops of the mains 

supply. This is particularly important for consumer appliances with electric motors or compressors. 

After  power  supply  has  been  recovered,  the  AVR  switches  on  within  6  or  180  seconds,  depending 

on the "Пауза (Pause)" button (Вкл./Выкл. (ON/ OFF)) 

h

 position. 

9. PROTECTION FUNCTION AGAINST HIGH AND LOW INPUT VOLTAGE, OVERLOAD AND 

OVERHEAT 

• 

The  stabilizer  is  equipped  with  an  unique  circuit  overvoltage  and  undervoltage  protection.  In  the 

case of mains voltage deviation over 260 V or below 140 V it turns off the load automatically. At the 

same  time  red  LED 

c

  illuminates,  and  the  display 

d

  shows  the  "H"  (for  activation  overvoltage 

protection)  or  symbol  "L"  (when  triggered  undervoltage  protection).  When  the  input  voltage  range 

returning to 140-260 V the stabilizer automatically resumes operation.

• 

In  case  of  overload  or  short-circuit  bimetallic  circuit-breaker 

i

  will  triggered.  After  elimination 

overload cause or short circuits, press circuit-breaker button 

i

 (RESET position), and stabilizer will 

resume operation.

10. TROUBLESHOOTING

If  none  of  the  above  methods  can  solve  the  problem,  please  seek  professional  advice  at  your 

nearest service center. Never attempt to repair the product yourself. 

The AVR does not start.

The AVR is in operation mode, 

but there is no output voltage. 

The AVR often produces 

clicking sound.

1. Press the switch once again.

2. Make sure there is electric 

power supply.

3. Disconnect part of the load  

and switch on the AVR again.
Please address to an authorized 

service center.

The AVR is regulating output 

voltage.
