Battery Features

The terminal supports peripheral devices designed for use with electronic point-of-

sale system such as biometric scanner and barcode reader.

Before connecting any peripheral device, make sure that the terminal is not

powered on. Reconnect the power cord only after you are finished connecting the

peripheral device(s). For complete information about peripheral installation and

use, refer to the user documentation supplied with those devices.

Connecting Peripheral Devices to the Terminal via the Micro-

USB Port

The terminal uses a single cell, 2450 mAh Li-ion battery (see

Documentation

for ordering information). The internal logic of the battery prevents

both overcharging and undercharging—a fault condition where the battery level

goes well below the minimum acceptable charge and the battery becomes

unusable.

The battery has a safety circuit that prevents cell damage from overcharge, over-

discharge, or overheating; and activates when the battery is left in an unused

terminal for extended periods.

•

The battery is not customer changeable and therefore should not be

disconnected and removed.

•

Li-ion batteries are not affected by shallow charging. When the terminal has

no external power source or battery, the coin cell battery provides power to the

security circuit.

•

Disconnecting and removing the battery, as well as unplugging the terminal

power pack, reduce the life of the coin cell battery, which does not recharge

and must be replaced when drained.

•

Conserve battery power by turning the terminal off when not in use.

•

Keep the Li-ion battery inserted in the terminal and power up the terminal

periodically to check the battery charge. Do not let the battery charge fall
