Battery Hotswapping
Important: When the internal battery power is Low or Very Low (Start > Settings > Power) connect the AC adapter to the MX9
before replacing the main battery pack.
When the main battery power level is low, the MX9 will signal the user with the low battery warning indicator (the Status LED
remains a steady red) that continues until the main battery is replaced, the battery completely depletes, or external power is
applied to the MX9 using an AC Adapter.
You can replace the main battery by first placing the MX9 in Suspend Mode then removing the discharged main battery and
installing a charged main battery within a five minute time limit (or before the Super-cap internal battery depletes). When the
main battery is removed the MX9 enters Critical Suspend state; the MX9 remains in Suspend mode, the display is turned off
and the internal battery continues to power the unit for at least five minutes.
Though data is retained, the MX9 cannot be used until a charged main battery is installed. After installing the new battery,
press the Power key. Full operational recovery from Suspend can take several seconds while the client is reestablishing a
network link. If the internal battery depletes before a fully charged main battery can be inserted, the MX9 will turn Off.
Low Battery Warning
It is recommended that the main battery pack be removed and replaced when its energy depletes. When the main battery Low
Battery Warning appears (the Status LED remains a steady red) perform an orderly shut down, minimizing the operation of any
installed devices and insuring any information is saved that should be saved.
Super-cap Internal Battery
The MX9 has an internal battery that is designed to provide limited-duration electrical power in the event of main battery failure.
The energy needed to maintain the internal battery near full charge at all times is drawn from the MX9 main battery. It takes 5
minutes or less to fully charge the internal battery. The duration of internal battery life is dependent upon operation of the MX9,
its features and any operating applications. The internal battery has a minimum service life of two years. The Super-cap
internal battery is replaced by Honeywell.
Handling Batteries Safely
l Never dispose of a battery in a fire. This may cause an explosion.
l Do not replace individual cells in a battery pack.
l Do not attempt to pry open the battery pack shell.
l Be careful when handling any battery. If a battery is broken or shows signs of leakage do not attempt to charge it.
Dispose of it using proper procedures.
Caution
Nickel-based cells contain a chemical solution which burns skin, eyes, etc. Leakage from cells is the only possible way for
such exposure to occur. In this event, rinse the affected area thoroughly with water. If the solution contacts the eyes, get
immediate medical attention.
NiMH and Li-Ion batteries are capable of delivering high currents when accidentally shorted. Accidental shorting can occur
when contact is made with jewelry, metal surfaces, conductive tools, etc., making the objects very hot. Never place a battery
in a pocket or case with keys, coins, or other metal objects.
