Chapter 2Hardware Setup Power for the Hand-held Monitor
The Hand-held Monitor can be operated using its built-in battery, or connected to either
115 volt or 230 volt AC power. A battery pack must always be installed to operate the HHM,
even when using AC power.
An optional 230VAC P ower A dapter can be used to connect the Han d-held Monitor Charger
to variety of 230 VAC power outlets. See page 2-2 for more information.
Charging the Battery Pack for AC Operation
To operate the HHM using AC power, if the battery pack is new or has become fully
discharged by operating the HHM on batte ry power, it must be charged for at least 20
minutes. If it is necessary to restore tempo rary operation before charging is complete:
Plug the adapter cable into the HHM.
Wait 15 seconds and power up the HHM. It may be necessary to remove the battery pack
for 15 seconds, then reinstall it.
Note that continually using the Hand-he ld Monitor in AC mode for an extended period of
time causes the battery pack to deteriorate. After up to two years of AC operation of the
HHM, the battery pack may not be able to accept enough charge to operate the HHM
independently. However, it can still be used for AC operation.
Selecting 120 VAC or 230 VAC
Before plugging the adapter into AC power to operate or charge the Hand-held Monitor,
be sure the switch at the base of the adapter is correctly set to match the incoming
power (120 volts AC or 230 volts AC).
