Operation
1. Charge the Battery:
This battery can be charged from any 110V or 220V AC power source with the
provided AC charger. Plug the AC charger into the battery input port to charge the battery.
CAUTION:
DO NOT connect any device to the battery output port when the battery is under
charging. The port III output voltage will be ~ 12.6V when the battery is charging.
The LED on the right will light up red. The remaining three LEDs will light up green and indicate the
charge level of the battery. One green LED indicates 30-60% battery charge, two green LEDs indicate 60-
90% battery charge, and all three green LEDs indicate a full charge.
NOTE:
New batteries may stop charging before they are fully charged. If your battery stops
charging, remove the charger from the battery and reinsert it, reinitiating the charge
cycle. This may happen several times during the first few charges and is normal.
Battery may become warm during charging process. It is recommended to recharge
the battery before it is fully exhausted.
2. Set Output Voltage:
Output port III can output three different voltages: 16V, 19V and 24V. When you
plug an output cord into the port, a LED will light up to indicate the current active output voltage. The
LEDs from right to left are 16V, 19V and 24V.
NOTE:
Bacharach PGM-IR and H25-IR PRO dual-power instruments are designed to run at
16V.
To change the output voltage, first remove the output cable from the port (voltage locks whenever an
output cable is present.) Press and hold the “CHECK” button for three seconds. The LED that represents
the currently selected voltage will begin to flash. Press the check button again to switch to the next
voltage. When the desired voltage is reached, wait five seconds for the LED to stop flashing and the
voltage will be selected.
3. Connect To Monitor:
Once the battery is charged and the correct voltage is selected, connect the
battery to your monitor as described in the user manual.
