Preparing the EP10 for Operation

2.4.1

The Batteries - 2400 mAh and 3600 mAh Lithium Ion

Two Lithium-Ion battery pack variants are available for the EP10: High Capacity 3600 mAh battery
pack, Model Number RV3010 (BP08-000760) and Standard Capacity 2400 mAh battery pack, Model
Number RV3005 (BP08-000730).
Before charging the battery, it is critical that you review the battery safety guidelines in the "EP10
Hand-Held Warranty & Regulatory Guide", PN 8000235.
Important: Always switch the unit off before changing the battery (see "Switching the EP10
Hand-Held Off" on page 11). If you do not turn the hand-held off before removing
the battery, it may be necessary to reboot the unit. Any active sessions may
be lost.
Battery packs shipped from the factory are charged to approximately 40% and must be fully charged prior
to use. Batteries can be charged using a variety of chargers and docking stations along with an EP10 inter-
nal charger. When using the internal charger, a suitable power source is required. All chargers and docking
stations are described in Chapter 6: "Peripheral Devices & Accessories".
2.4.2

Installing the Battery

• Match the contacts at the bottom of the battery with those in the battery well of the EP10 hand-held,
and gently snap into place.
2.4.3

Removing the Battery

• Slide the battery release button (located just above the battery) to the right to release and remove the
battery from the unit.
2.4.4

Switching the EP10 Hand-Held On

• Press and release the [Power] button.
The centre LED flashes yellow and the desktop Today screen is displayed.
Note: If the EP10 was already in use, pressing the [Power] button 'wakes' it from suspend. The
screen in which you were working prior to the suspend state is displayed.
Important: If your EP10 fails to power up, consider the following troubleshooting options: the
battery capacity may be lower than the suspend threshold, it may be
overheated (>60° C), or the battery may have fallen below the configured
suspend threshold. Refer to Section 5.6.4 on page 102 for additional details about
this setting.
If you provide AC power to the EP10 and either the battery capacity is too low or is
overheated, a yellow LED will flash and the unit will not switch on. To switch on the
hand-held, replace the overheated battery or, in the case of a depleted battery, wait
for the capacity to reach an acceptable level.
However, if you provide AC power to an EP10 with a battery that falls below the
configured suspend threshold, the hand-held will switch on provided the battery
capacity is above 0 mAh.
2.4.5

Switching the EP10 Hand-Held Off
