External Power

See item 3 in Fig.2.2 and Fig.2.3.

2250 Light is powered by an internal rechargeable battery pack. An indication of available

charge is shown by the battery icon at the bottom of the screen. If the charge remaining is

low or empty, the batteries can be recharged by connecting Mains Power Supply ZG-0426 or

ZG-0429 to the ‘Ext. Power’ socket. When the power supply lead is connected, the

icon will be displayed in place of the battery icon.

CAUTION:

• Use specified battery charger only

• Charging below 0

°C (32°F) is not recommended. If you charge the battery pack below 0°C,

the lifetime of the batteries will be reduced

• Do not charge battery pack at temperatures above 60

°C

• Do not disassemble or expose battery pack to fire or water

Battery Charge Indicator

See item 4 in Fig.2.2 and Fig.2.3.

A battery charge light, (LED), indicates when the battery pack is being charged from external

power.

• With hardware versions 1 – 3: The LED is a steady green light when external power is

applied (and the battery is charging), and a flashing green light when charging has finished

• With hardware version 4 (G4): The LED is red when external power is applied (and the

battery is charging); green when the battery is completely charged; and blue to indicate

that the unit is in stand-by and battery powered

Located above the USB connector, it is used to reset 2250 Light if you have problems with the

instrument and cannot get it to operate. To reset, press the button with the point of the stylus.
