Ultraview 1030/1050 Monitors — Service Manual
2-3
Setup
Nickel Metal Hydride (NiMH)
NiMH batteries are shipped in a discharged state and will require some conditioning and charging
prior to use. When the batteries are received new, place them into a monitor not attached to AC
power and turn the monitor ON so that it runs on battery power alone. After the monitor has shut
itself OFF and the battery is discharged, attach the external power supply to the unit. Verify that
the green LED is flashing and let the batteries (or battery) charge for a minimum of two (2) hours.
Be sure that the monitor is turned OFF to expedite the charging process. After the LED on the front
of the monitor has stopped flashing, disconnect the AC brick from the unit again and turn the unit
ON, allowing it to discharge the batteries again and turn itself OFF. Repeat this process for three
(3) charge/discharge cycles. Completing the above procedure will ensure that the batteries
perform up to their maximum capacity during their first use in the field.
A NiMH battery will exhibit a substantial increase in “cycle life” or the number of charge/discharge
cycles, compared to an SLA battery, before the end of its life.
Battery Use
Batteries may be changed during battery or AC operation without losing data, provided that one
charged battery remains connected at all times during the exchange.
During AC operation and with batteries installed, the green LED (front, lower right of monitor as
shown in Figure 2-3) flashes to indicate changes in the status of the batteries:
• Constant green — the battery is fully charged
• Slow flash — the battery is being charged
• Three quick flashes followed by one slow flash — the battery is bad
During battery operation, the green LED will not be lit.
Battery Storage and Maintenance
Sealed Lead Acid (SLA)
If the monitor is not expected to be used for a long time, it is recommended that the batteries be
removed from the unit and stored separately. The batteries should be stored under the following
conditions:
• Low humidity
• 5° to 104° F (-15° to +40° C)
• Away from direct sunlight
