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.
