Motorola MC9090-G ユーザーズマニュアル

Getting Started

1 - 5

Before using the mobile computer for the first time, charge the main battery until the amber charge indicator light 
remains lit (see 

 for charge status indications). Charge time is less than four hours. The 

mobile computer can be charged using a cradle, the CAM with a charging cable, or the MSR with the appropriate 
power supply.

The mobile computer is equipped with a memory backup battery which automatically charges from the 
fully-charged main battery. When the mobile computer is used for the first time, the backup battery requires 
approximately 15 hours to fully charge. This is also true any time the backup battery is discharged, which occurs 
when the main battery is removed for several hours. The backup battery retains data in memory for at least 30 
minutes when the mobile computer's main battery is removed. When the mobile computer reaches a very low 
battery state, the combination of main battery and backup battery retains data in memory for at least 72 hours.

Do not remove the main battery within the first 15 hours of use. If the main battery is removed before the backup battery 
is fully charged, data may be lost.

Use the following to charge batteries:

Cradles: The mobile computer slips into the cradles for charging the battery in the mobile computer (and 
spare batteries, where applicable).

Single Slot Serial/USB Cradle.

Four Slot Ethernet Cradle and Four Slot Charge Only Cradles.

Accessories: The mobile computer’s snap-on accessories provide charging capability, when used with one of 
the accessory charging cables.

CAM

MSR.

Chargers: The mobile computer’s spare battery charging accessories are used to charge batteries that are 
removed from the mobile computer. 

Single Slot Serial/USB Cradle

Four Slot Spare Battery Charger

Universal Battery Charger (UBC).

To achieve the best battery life in mobile computers with multiple radios, turn off the radios that are not 
being used. This can be accomplished via the SetDevicePower() API (refer to the SMDK Help File for 
Symbol Mobile Computers) or via the Control Panel application (tap Start > 9000 Demo > Ctl Panel 
icon).
