Safe Charging Temperature Range

The internal temperature of the Thor VM2 is the trigger for UPS battery charging.
• The UPS battery is not charged when the internal Thor VM2 temperature is below 0°C (32°F). This corresponds to
an ambient (room) temperature of approximately -10°C (-14°F).
• The UPS battery is not charged when the internal Thor VM2 temperature is above 45°C (113°F). This corresponds
to an ambient (room) temperature of approximately 35°C (95°F).
• If the UPS battery cannot be charged due to a temperature extreme, the
the Thor VM2 to a different location to charge the UPS battery.
When the Thor VM2 is operated in an environment where the UPS battery is not able to charge due to temperature
extremes, the Thor VM2 should be removed to a location within the safe charging temperature range during off hours.
A discharged UPS battery cannot protect against data loss in the event vehicle power is interrupted.

Charging Timeout

• A fully discharged UPS battery normally recharges in less than 4 hours when the Thor VM2 is in a powered dock and
within the safe charging temperature range.
• If the UPS battery is not charged before an 8 hour (or 4 hours for some earlier software revisions) timeout period
expires, the UPS Status LED
• The charge timeout is reset if charging resumes upon application of external power.
• The charge timeout is reset if charging resumes when the Thor VM2 enters the permissible temperature range for
charging.
• If the charge timeout occurs, remove the Thor VM2 from the dock and
the Thor VM2 in the dock and power on.

Charging and Power Management

• Charging does not occur when the Thor VM2 is in ignition mode and the ignition is inactive.
• Charging of the UPS battery continues when the Thor VM2 is in power management (user idle, system idle or
suspend modes).

Backup Battery

The Thor VM2 has a permanent Lithium battery installed to maintain time, date and CMOS setup information for a minimum
of 90 days. The lithium battery is not user serviceable and should last four years with normal use before it requires replace-
ment.
Note: The backup battery should only be changed by authorized service personnel.

Power Management Modes

The Thor VM2 supports the standard Microsoft Windows CE power management modes: On (D0), Backlight Off (D1), Dis-
play Off (D2) and Suspend (D3).
(page 3-16) is amber.
The Thor VM2 uses an 8A time delay (slow blow) fuse that is externally accessible and user
replaceable. The fuse is located on the back of the dock. The fuse is accessed by unscrewing
the cap as indicated.
Should it need replacement, replace with same size, rating and type of fuse:
• Littelfuse 0215008.MXP
• Cooper Bussmann BK1/S506-8-R
• Bel Fuse 5HT 8-R
or equivalent.
Fuse has voltage on it even when power is off. Always disconnect input power before changing
the fuse.
