The batteries may be replaced without breaking a seal. The Receiver is powered by a battery
pack. The battery pack can be replaced with 5 disposable or rechargeable AA batteries.
The replacement batteries need to be installed in a dedicated box, which is to be installed in the
original battery compartment and wired to the device. Power supply voltage is from 7.5 V to 5.2 V.
The Receiver has a battery level indicator, and it goes off automatically to avoid excessive dis-
charge when the battery is low. The Receiver is switched to a battery charging mode when the power
supply unit is connected. The Receiver secures the battery against overcharge.
NOTE!

Before charging, make sure that a rechargeable battery is put into the battery compart-
ment. If the battery case contains non-rechargeable batteries when charging, this may
cause damage to the receiver.

The ambient temperature shall be from plus 10ºС to plus 30ºС when charging. Charging
at other temperatures may reduce battery life.
Recharge the battery pack by plugging the charger to the respective charging port of the Receiver
(item 1 in Fig. 7 ). Plug the power charger to a 230 V outlet. The battery pack charging process is indi-
cated on the display by filling out the battery icon in black ( ). When the battery pack is
fully charged, the battery icon is fully black. If completely drained, the battery pack will take 6 to 8
hours to recharge.
During prolonged storage of the Receiver, it is recommended to recharge the battery pack every
three months.
