Battery best practices for the MC3090
General Information
The MC3090 comes shipped from SSCS with a standard lithium-polymer battery.
This battery is charged with the single slot serial/USB cradle that comes with
the device. An idle MC3090 with a full charge will last about 11 days before the
programming and data in memory is lost. A unit with a completely drained or
removed main battery will last a much shorter time (a few days on the backup
battery according to manufacturer specifications). It is critical that the unit
be left in a powered cradle when not in use. The standard battery usually fully
charges in less than four hours.
The MC3090 will last for at least 4 1/2 hours of continuous scanning using
the standard 2600mAh battery. Since the standard battery fully charges in less
than four hours, it is recommended that a spare battery be kept on the charger
while scanning, so that when the battery being used dies, it can be immediately
replaced. The dead battery can then take its place on the battery charger which
can be found in the rear part of the cradle.
Charging the Battery
Use the device cradles, cables and spare battery chargers to charge the
MC3090. The main battery can be charged before insertion into the mobile
computer or after it is installed. Use a cradle to charge the main battery while
it is installed in the mobile computer. Before using the mobile computer for the
first time, fully charge the main battery until the amber Charge LED Indicator
remains lit.
Batteries must be charged in an environment that falls within the range of 32
to 104 degrees Fahrenheit.
Memory Backup Battery
The device is equipped with a memory backup battery which automatically
charges whether or not the device is operating or in suspend mode. When the
mobile computer is used for the first time or after the memory backup battery
has fully discharged, the memory backup battery requires approximately 15 hours
to fully charge. Do not remove the main battery from the device while it is
charging in the cradle for 15 hours to ensure that the memory backup battery
fully charges.
Extending Your Battery's Life
Because a fully charged battery is critical to preventing data loss, here are
some tips that you can use to help ensure your battery retains its charge for
the maximum amount of time:
- When swapping out a battery with a low charge it is important that
the backup battery has enough of a charge to retain data on the MC3090 while
the batteries are being swapped. Do not remove the main battery when the
backup battery is very low or dead (see "When to Replace or Recharge
Batteries" in Chapter 5 of the HDP6 User's Guide for
how to determine the backup battery is low). ALWAYS send any pending DSD or
Inventory transactions to the HDP Application before swapping batteries to avoid
unexpected and irrevocable data loss.
- Turning off the MC3090’s built-in wireless
application radio when it is not bound to a wireless network can extend the
battery’s life by almost 50%. In HHS version 1.2 and later this application is
automatically disabled when HHS is launched. To re-enable the wireless
application radio, if you have need to use it, see "Enabling and Disabling the
Wireless Application Radio" in Chapter 5 of the of the HDP6 User's Guide.
If you are a user of HHS previous to
version 1.2, see "Disabling the Wireless Application Radio (HHS Previous to Ver
1.2)" in Chapter 5 of the HDP6 User's Guide.
- Pressing FUNC+S on the MC3090’s keypad places the device in
power savings mode and dims the back light. To return to normal power and
backlight settings click FUNC+N.
