Printek FieldPro RT43 - Manual (Page 17)

Daily Operation
Battery Charging
The FieldPro RT43 contains battery monitoring and charging circuitry so that the battery may be charged while
in the printer. Charging the battery in the printer requires an optional power supply. Printek offers power
supplies for use with 100-240VAC/50-60Hz and 12/24VDC for vehicle applications.
The printer’s Battery Indicator flashes whenever the battery needs recharging.
To charge the battery, connect the power supply to the appropriate source, and connect the output of the supply
to the printer’s power connector shown in Figure 10.
Caution: Use only Printek power supplies to power your printer and charge batteries. Other power supplies
may damage the electronics and printing mechanism. Damage caused by use of a non-Printek power
supply will not be covered by the printer’s warranty.

When the power supply is connected, the printer’s charging circuitry will determine if the battery currently
requires charging and if so, will turn on the Battery Indicator until the battery has reached sufficient charge.
Depending on the condition of the battery, charging may take up to 2½ hours to complete. When fully charged,
the Battery Indicator will turn off.
Leaving the power supply connected to the printer will cause the printer to continuously monitor the condition
of the battery and keep the battery charged.
