Replacing the remote control battery (Granta 2190)

The remote control contains a CR2032 lithium battery with an initial supply voltage of 3 volts. If the supply voltage of the remote control is within the normal range, then each time you press any button on the remote control, the remote control indicator lights up with a short flash. If, when you press any button on the remote control, the indicator lights up with two short flashes or does not light up at all, then the battery should be replaced with a new one. To do this, follow these steps:

• remove screw 2 (figure 55) from the side of the body opposite the control buttons:
• using a flat-head screwdriver, separate the housing halves by inserting the screwdriver into slot 1;
• remove the board from the case;
• replace battery 3 with a new one, observing the polarity of the connection;
• insert the board into the case;
• snap the housing halves together and tighten screw 2.

Warning! Do not use any other type of battery in the remote control.
