Battery Operation
The HHM’s battery pack provides up to 6 hours of operation. To maximize battery life,
allow the battery to discharge fully between charges. The battery should be allowed to
fully discharge once a month.
Low Battery Power
Low battery power may cause this message:
* * L O W B A T T E R Y * *
* * H H M H A L T E D * *
P l e a s e R e c h a r g e
Or the display may blank, or two black lines may appear briefly. Low battery power
suspends the current operation.
Charging the Battery Pack
When you receive a new Hand-held Monitor, its battery pack is not charged. Before
using a new battery pack to power the HHM for the first time, charge it by plugging the
adapter into a power source for 24 hours. After this initial charging, subsequent
rechanges will require only 16 hours.
Maintaining spare battery packs will allow the HHM to operate using one battery pack
while another is being charged.
If the battery pack won’t take a charge, it usually indicates a faulty battery pack, not a
faulty Hand-held Monitor. Try another battery pack. Replacement (uncharged) battery
packs are available.
If a battery pack is left uncharged for a long time, it may be necessary to remove the
battery pack from the HHM and charge it while removed for up to 15 minutes.
Replacing the Battery Pack
To replace the battery pack, use a Phillips screwdriver (size 0 or 1) to release the retaining
screw at the bottom of the HHM. Slide the battery pack out, insert another, and tighten
the screw.
Automatic Shutoff
To conserve power, the Hand-held Monitor automatically shuts off 10 minutes after the
last key is pressed. For applications where continual operation is preferred, the
automatic shutoff feature can be disabled. See page 3-5 for more information.
